How Credit Card Processing Actually Works: A Step-by-Step Guide for Business Owners

A customer taps a card, the terminal says “approved,” and the money appears in your bank account a day or two later.

It feels simple.

Behind that transaction, however, several companies communicate with one another in a matter of seconds. The payment must be authorized, routed through the correct card network, approved by the customer’s bank, submitted for settlement, and deposited into the business’s account.

Each party plays a different role, and each may receive a portion of the processing cost.

Understanding how credit card processing actually works can help you make better decisions about pricing, equipment, fraud prevention, funding, and choosing a payment processor.

This guide explains the entire process in plain English.

What Is Credit Card Processing?

Credit card processing is the system that allows a business to accept a customer’s credit or debit card as payment.

The process includes several stages:

1. The customer presents a card.
2. The transaction is sent for authorization.
3. The issuing bank approves or declines the transaction.
4. The business submits approved transactions for settlement.
5. Funds move through the payment system.
6. The business receives a deposit.

Most authorization decisions happen within a few seconds.

The actual transfer of money usually occurs later during settlement and funding.

The Main Parties Involved in a Credit Card Transaction

Before looking at the transaction step by step, it helps to understand the companies involved.

The Cardholder

The cardholder is the customer using the credit or debit card.

The card may be:

• A physical credit card
• A debit card
• A business card
• A mobile wallet
• A virtual card
• A stored card used for recurring billing

The Merchant

The merchant is the business accepting the payment.

The merchant may accept payments through:

• A countertop terminal
• A point-of-sale system
• A mobile card reader
• An online checkout page
• A virtual terminal
• An invoice payment link
• A recurring billing system
• A kiosk

The Issuing Bank

The issuing bank is the financial institution that issued the customer’s card.

Examples include the bank or credit union whose name appears on the card.

The issuing bank decides whether to approve or decline the transaction based on factors such as:

• Available credit
• Account balance
• Fraud concerns
• Card status
• Transaction limits
• Geographic activity
• Security controls

The Acquiring Bank

The acquiring bank, sometimes called the merchant bank, supports the merchant’s ability to accept card payments.

The acquiring side of the transaction receives payment information from the merchant and helps route it through the payment system.

Depending on the processing arrangement, the merchant may interact more frequently with a payment processor or merchant-services provider than with the acquiring bank directly.

The Payment Processor

The payment processor handles the communication between the merchant, acquiring bank, card network, and issuing bank.

The processor may provide or support:

• Transaction routing
• Authorizations
• Settlement
• Funding
• Merchant statements
• Fraud tools
• Chargeback management
• Customer support
• Payment equipment
• Reporting

The processor is a major part of the infrastructure that allows the transaction to move from the merchant to the cardholder’s bank and back again.

The Card Network

The card network creates the rules and communication pathways used to route transactions.

Major card networks include:

• Visa
• Mastercard
• Discover
• American Express

The card network does not usually issue the card itself. Instead, it helps connect the issuing bank and the acquiring side of the transaction.

The Payment Gateway

A payment gateway securely transmits payment information for online and certain card-not-present transactions.

It acts as a digital bridge between the merchant’s website or software and the payment processor.

A gateway may also provide:

• Tokenization
• Fraud screening
• Recurring billing
• Card-on-file storage
• Address verification
• Security controls
• Payment links
• API integrations

Not every in-person transaction requires a separate gateway, but most e-commerce transactions involve one.

Step 1: The Customer Presents a Card

The process begins when the customer provides payment information.

This may happen through:

• Inserting a chip card
• Tapping a contactless card
• Using a mobile wallet
• Swiping a magnetic stripe
• Entering card information online
• Providing card information over the phone
• Paying an emailed invoice
• Using a stored card

The method used to collect the card affects both security and processing cost.

For example, an in-person chip transaction usually provides stronger proof that the card was physically present than a manually keyed transaction.

Card-not-present transactions generally carry more fraud risk and may cost more to process.

Step 2: The Terminal or Software Encrypts the Payment Data

The terminal, POS system, gateway, or payment application captures the transaction information.

This may include:

• Card number
• Expiration date
• Transaction amount
• Merchant identification
• Terminal identification
• Transaction type
• Security information
• Billing address details
• Card verification data

Modern payment systems use encryption and tokenization to reduce the exposure of sensitive card information.

Encryption

Encryption converts payment data into a protected format while it is being transmitted.

Tokenization

Tokenization replaces the actual card number with a substitute value called a token.

The token may be used for future payments without requiring the business to store the full card number.

These tools help reduce the risk of card data being exposed.

Step 3: The Transaction Is Sent to the Payment Processor

The merchant’s terminal, software, or gateway sends an authorization request to the payment processor.

The authorization request asks a basic question:

Should this transaction be approved?

The processor routes the request through the appropriate card network.

For example, a Visa transaction is routed through the Visa network, while a Mastercard transaction is routed through the Mastercard network.

Step 4: The Card Network Sends the Request to the Issuing Bank

The card network identifies the bank that issued the customer’s card and forwards the authorization request.

The issuing bank evaluates the transaction.

It may review:

• Available funds or credit
• Card status
• Transaction amount
• Recent activity
• Fraud indicators
• Merchant type
• Location
• Security data
• Cardholder restrictions

The bank then sends back an approval or decline response.

Step 5: The Issuing Bank Approves or Declines the Transaction

The issuing bank sends a response through the card network and payment processor to the merchant.

The transaction may be:

• Approved
• Declined
• Referred for additional verification
• Partially approved
• Flagged for another action

When a transaction is approved, the issuing bank places a hold on the customer’s available funds or credit.

This does not always mean the money has already reached the business.

Authorization confirms that the transaction may proceed. Settlement and funding happen later.

What Is an Authorization Code?

An approved transaction typically receives an authorization code.

This code confirms that the issuing bank approved the request at that moment.

An authorization code does not guarantee that a transaction can never be disputed or reversed.

The customer may still:

• Request a refund
• Dispute the transaction
• Report fraud
• File a chargeback

The code is simply evidence that the issuing bank approved the transaction during authorization.

Common Reasons a Card Is Declined

A card may be declined because of:

• Insufficient funds
• Insufficient available credit
• Incorrect card information
• Expired card
• Fraud concerns
• Card reported lost or stolen
• Daily transaction limits
• International restrictions
• Billing-address mismatch
• Incorrect security code
• Network communication issue
• Issuing-bank restrictions

The merchant usually receives only a short response code rather than a detailed explanation.

For security reasons, the customer may need to contact the issuing bank directly.

Step 6: The Merchant Completes the Sale

After approval, the merchant completes the transaction and provides the customer with the product or service.

The approved transaction is stored in the terminal, POS system, gateway, or processor platform until it is submitted for settlement.

At this stage, the transaction has been authorized but may not yet be fully settled.

Step 7: Approved Transactions Are Collected Into a Batch

Most businesses submit approved transactions in a group called a batch.

A batch may be closed:

• Automatically at a scheduled time
• Manually by the merchant
• Once each business day
• Multiple times per day
• Through the POS or payment gateway

Closing the batch tells the processor that the merchant is ready to settle those transactions.

Businesses should confirm that batches close properly.

A transaction that is authorized but not submitted for settlement may not be funded correctly.

Delayed settlement can also affect processing costs in some situations.

Step 8: The Batch Is Submitted for Settlement

The processor submits the batch through the card networks.

The card networks calculate the amounts owed by the issuing banks and coordinate the movement of funds.

During settlement:

• The issuing bank releases the transaction funds.
• Interchange and card-brand fees are assessed.
• Funds move to the acquiring side of the transaction.
• The processor prepares the merchant deposit.
• Processing fees may be deducted, depending on the account structure.

This part of the process usually happens after the customer has already left the business.

Step 9: Funds Are Deposited Into the Merchant’s Bank Account

After settlement, the processor or acquiring bank sends the merchant’s funds to the designated business bank account.

This is called funding.

Funding times vary based on:

• Processor
• Bank
• Business type
• Risk level
• Batch-close time
• Weekends
• Holidays
• Transaction type
• Account history
• Funding program

Many businesses receive funds within one or two business days, although some may qualify for faster funding.

Other businesses may experience longer funding periods because of risk, account setup, or industry requirements.

Gross Funding vs Net Funding

Merchant deposits may be handled in different ways.

Gross Funding

With gross funding, the business receives the full amount of its settled sales.

Processing fees are deducted separately, often once per month.

For example:

• Settled sales: $10,000
• Deposit: $10,000
• Processing fees deducted later: $290

Net Funding

With net funding, processing fees are deducted before the deposit reaches the business.

For example:

• Settled sales: $10,000
• Processing fees: $290
• Net deposit: $9,710

Neither approach is automatically better.

The important thing is knowing how your processor handles deposits so you can reconcile your bank account accurately.

What Happens to the Processing Fee?

The amount your business pays is generally divided among several participants.

Interchange

Interchange is generally paid to the bank that issued the customer’s card.

It compensates the issuing bank for participating in the transaction and accepting certain risks.

Interchange may vary based on:

• Credit or debit
• Consumer or business card
• Basic or premium rewards card
• Transaction amount
• Merchant category
• In-person or online payment
• Data submitted
• Settlement timing

Card-Brand Fees

The card networks may charge assessments and other network-related fees.

These fees support the payment infrastructure and network services.

Processor Markup

The processor or merchant-services provider charges a markup for its services.

This may include:

• Percentage markup
• Per-transaction fee
• Monthly account fee
• Gateway fee
• Software fee
• Equipment fee
• Support fee
• Other administrative charges

Understanding the difference between interchange, card-brand fees, and processor markup is essential when comparing processing proposals.

A Simple Example of a $100 Credit Card Transaction

Assume a customer makes a $100 purchase.

The customer sees a $100 charge.

The merchant does not necessarily receive the full $100 after fees.

A simplified example might look like this:

• Customer payment: $100
• Interchange and card costs: $1.90
• Processor markup and transaction fees: $0.40
• Net amount before other monthly fees: $97.70

The exact amounts will vary based on:

• Card type
• Pricing model
• Merchant category
• Transaction method
• Processor markup
• Monthly account charges

This example is only meant to show how the transaction amount is divided.

Why Some Transactions Cost More Than Others

Not every credit card transaction has the same processing cost.

Several factors influence pricing.

Credit vs Debit

Debit transactions may follow different pricing structures than credit transactions.

Regulated debit cards may also be subject to different rules than non-regulated debit cards.

Basic Cards vs Rewards Cards

Premium rewards cards may carry higher interchange costs because the card issuer provides points, miles, cash back, or other benefits to the cardholder.

Consumer Cards vs Commercial Cards

Corporate, purchasing, fleet, and business cards may have different interchange categories.

Some commercial transactions may qualify for better rates when additional data is submitted.

In-Person vs Online Transactions

In-person chip and contactless transactions usually provide stronger card-present verification.

Online, phone, invoice, and manually keyed transactions generally involve greater fraud risk.

Higher risk often means higher processing costs.

Chip vs Swipe

EMV chip transactions provide stronger security than traditional magnetic-stripe transactions.

Swiped transactions may carry more risk, particularly when a chip card is swiped instead of inserted.

Keyed Transactions

Manually entering a card number may result in higher costs because the physical card may not be present.

Using address verification and other security tools may help reduce risk.

Transaction Size

A transaction may include both:

• A percentage fee
• A fixed per-transaction fee

The fixed fee has a larger impact on low-ticket transactions.

For example, a $0.10 transaction fee represents:

• 1% of a $10 sale
• 0.1% of a $100 sale

That is why coffee shops, convenience stores, and other low-ticket businesses must pay close attention to per-transaction pricing.

Merchant Category

The card networks assign businesses a merchant category code based on their primary activity.

Different business categories may have different interchange programs, risk profiles, and underwriting requirements.

How Online Credit Card Processing Works

Online transactions follow the same general authorization and settlement process, but they involve additional technology.

The customer enters payment information into a website or online checkout page.

The payment gateway encrypts and transmits the information to the processor.

The transaction is routed to the card network and issuing bank.

The approval or decline message returns to the website.

The approved transaction is later settled and funded.

Online merchants may also use:

• Address Verification Service
• Card verification codes
• Fraud scoring
• Device recognition
• IP address monitoring
• 3-D Secure
• Tokenization
• Velocity controls
• Recurring billing tools

Because the card is not physically present, online transactions may carry greater chargeback and fraud risk.

How Mobile Wallet Payments Work

Mobile wallets include services that allow customers to pay using a smartphone, smartwatch, or other compatible device.

The customer may tap the device near a contactless terminal.

The mobile wallet typically uses tokenization so the merchant does not receive the customer’s actual card number.

The transaction still travels through the processor, card network, and issuing bank.

Mobile wallet payments can provide:

• Fast checkout
• Contactless acceptance
• Tokenized payment data
• Device-based authentication
• Reduced exposure of the actual card number

How Debit Card Processing Works

Debit cards may be processed in different ways.

Signature Debit

A signature debit transaction is generally routed through a major card network and processed similarly to a credit transaction.

The customer may not actually provide a signature, despite the name.

PIN Debit

A PIN debit transaction requires the customer to enter a personal identification number.

It may be routed through a debit network.

The cost structure may differ from signature debit, depending on transaction size, network, and processor pricing.

The most affordable routing option can vary based on the business and average ticket.

What Is a Pending Transaction?

A pending transaction has been authorized but has not yet fully settled.

The customer’s available balance or credit may be reduced while the transaction is pending.

Pending transactions may change before settlement because of:

• Tips
• Final invoice amounts
• Fuel purchases
• Hotel deposits
• Car-rental holds
• Restaurant adjustments
• Voids

The pending amount may disappear or be replaced with the final settled transaction.

What Is a Preauthorization?

A preauthorization places a temporary hold on a customer’s available funds or credit.

Preauthorizations are common in industries where the final amount is not known immediately.

Examples include:

• Hotels
• Car rentals
• Gas stations
• Restaurants
• Equipment rentals

The merchant later completes the transaction using the final amount.

Preauthorization policies should be clearly communicated because customers may temporarily have less available credit or money.

What Is a Void?

A void cancels a transaction before it is settled.

Voiding a transaction may prevent it from appearing as a completed charge, although the customer may still see a temporary pending authorization.

A void is different from a refund.

What Is a Refund?

A refund occurs after a transaction has been completed or settled.

The merchant sends money back to the customer through the payment system.

Refunds may take several business days to appear in the customer’s account.

Depending on the processor and pricing structure, the merchant may not receive all original processing costs back.

What Is a Chargeback?

A chargeback occurs when the cardholder disputes a transaction through the issuing bank.

The issuing bank may temporarily or permanently remove the transaction amount from the merchant.

The merchant may also be charged a chargeback fee.

Common reasons for chargebacks include:

• Fraud
• Product not received
• Service not provided
• Duplicate billing
• Incorrect amount
• Unrecognized business name
• Recurring billing dispute
• Refund not processed
• Product not as described

The merchant may respond with evidence such as:

• Signed receipts
• Contracts
• Invoices
• Delivery confirmation
• Customer communications
• Refund policies
• Transaction records

Winning a chargeback is not guaranteed, even when the merchant believes the sale was valid.

Why Your Business Name Matters on a Customer’s Statement

The billing descriptor is the business name that appears on the customer’s card statement.

A confusing descriptor can lead to disputes when customers do not recognize the transaction.

Your descriptor should be:

• Recognizable
• Consistent with your brand
• Easy to understand
• Connected to the product or service sold

A recognizable billing descriptor is one of the simplest ways to reduce avoidable chargebacks.

What Is a Merchant Account?

A merchant account is an account arrangement that allows a business to accept card payments and receive settled funds.

It is not always the same as the business’s regular checking account.

Funds pass through the merchant-processing system before being deposited into the business bank account.

Some modern payment providers use an aggregated model where multiple businesses operate under a larger master merchant arrangement.

Traditional merchant accounts are often underwritten individually.

Each model has advantages and limitations.

Traditional Merchant Account vs Payment Facilitator

Payment providers may use different account structures.

Traditional Merchant Account

A traditional merchant account is generally underwritten specifically for the business.

This may provide:

• Customized pricing
• More individualized risk review
• Greater account stability for established businesses
• Industry-specific configurations
• Dedicated merchant identification

Payment Facilitator Model

A payment facilitator allows businesses to begin processing under a larger shared platform.

This model is commonly associated with fast online signup.

It may provide:

• Quick onboarding
• Simple pricing
• Easy setup
• Integrated software

However, automated risk monitoring may result in sudden holds, reviews, or account restrictions when activity falls outside expected patterns.

The right structure depends on the business.

Why Payment Processors Ask for Business Information

When a business applies for payment processing, the provider may request:

• Legal business name
• Tax identification number
• Ownership information
• Bank statements
• Processing history
• Average ticket
• Monthly volume
• Highest transaction amount
• Products or services sold
• Website
• Refund policy
• Delivery timeline
• Personal identification
• Banking information

This process is called underwriting.

The processor is evaluating factors such as:

• Fraud risk
• Chargeback exposure
• Financial stability
• Delivery obligations
• Industry risk
• Expected transaction activity

Accurate information helps prevent future account problems.

What Is a Reserve?

A reserve is money held by the processor or acquiring bank to cover potential losses.

A reserve may be required when a business has:

• High chargeback risk
• Long delivery times
• Future-service obligations
• Large transactions
• Limited processing history
• Financial instability
• Seasonal spikes
• A high-risk industry

Reserves may be structured as:

• Rolling reserve
• Upfront reserve
• Capped reserve
• Temporary hold
• Transaction percentage holdback

Businesses should understand when reserve funds will be released and under what conditions.

Why Deposits May Be Delayed

Funding may be delayed because of:

• Weekend or holiday timing
• Late batch closing
• Bank processing schedules
• Unusual transaction volume
• Large transactions
• Chargeback concerns
• Fraud review
• Missing account information
• Reserve requirements
• Processor risk monitoring
• Banking errors

A delayed deposit does not always mean something is wrong, but unexplained delays should be addressed promptly.

How Pricing Models Affect What You Pay

The underlying transaction process is similar across processors, but the way costs are presented can differ.

Flat-Rate Pricing

The business pays one basic percentage and transaction fee for broad transaction categories.

This is easy to understand but may be more expensive for higher-volume businesses.

Interchange-Plus Pricing

The business pays the actual interchange cost plus a stated processor markup.

This model can provide greater transparency.

Tiered Pricing

Transactions are grouped into qualified, mid-qualified, and non-qualified categories.

The lowest advertised rate may apply to only a limited portion of transactions.

Subscription Pricing

The business pays a monthly membership fee, interchange, and often a fixed transaction charge.

This can work for some higher-volume businesses, depending on total cost.

Dual Pricing

The business displays both a cash price and a card price.

Customers paying with cash receive the cash price, while card-paying customers pay the displayed card price.

The program must be properly designed, disclosed, and configured.

How to Calculate Your Effective Processing Rate

Your effective rate shows the total percentage of your card sales spent on processing.

Use this formula:

Total processing fees ÷ Total card sales × 100

For example:

• Total card sales: $80,000
• Total processing fees: $2,320

Calculation:

$2,320 ÷ $80,000 × 100 = 2.90%

Your effective rate is 2.90%.

This number helps you compare your actual processing cost over time.

It should be reviewed together with:

• Transaction count
• Average ticket
• Card mix
• Monthly fees
• Software charges
• Equipment costs
• Refunds
• Chargebacks

Common Credit Card Processing Fees

A merchant statement may include:

• Interchange
• Card-brand assessments
• Processor percentage markup
• Per-transaction fees
• Authorization fees
• Batch fees
• Monthly account fees
• Statement fees
• PCI compliance fees
• PCI noncompliance fees
• Gateway fees
• Virtual terminal fees
• Software fees
• Equipment fees
• Chargeback fees
• Annual fees
• Monthly minimums
• Early termination fees

Not every fee is necessarily unreasonable.

The key is knowing what each fee covers and whether it was properly disclosed.

Security Responsibilities for Businesses

Every business accepting cards has a responsibility to protect payment information.

Basic practices include:

• Use EMV-capable equipment
• Avoid writing down card numbers
• Limit employee access
• Use strong passwords
• Enable multifactor authentication
• Keep software updated
• Complete PCI compliance requirements
• Use secure internet connections
• Monitor refunds and voids
• Review user permissions
• Train employees on fraud
• Never send card data through unsecured email or text

Payment security is a shared responsibility among merchants, processors, banks, networks, software providers, and customers.

How to Choose a Payment Processor

Do not choose a processor based only on the lowest advertised rate.

Review:

• Total monthly cost
• Pricing model
• Processor markup
• Contract length
• Cancellation terms
• Equipment ownership
• Software compatibility
• Funding speed
• Customer support
• Chargeback assistance
• Reporting
• Security tools
• Industry experience
• Account stability

A reliable processor should be able to explain both the transaction process and the pricing in plain English.

Questions to Ask Your Payment Processor

Ask your provider:

1. What pricing model am I using?
2. What is your markup above interchange?
3. How quickly will my business receive deposits?
4. What time does my batch close?
5. Are fees deducted daily or monthly?
6. Do I have a traditional merchant account?
7. Are there funding holds or reserve requirements?
8. What equipment and software fees apply?
9. Do I own or lease the equipment?
10. What fraud-prevention tools are included?
11. What happens when I receive a chargeback?
12. Are there annual or cancellation fees?
13. Does the agreement automatically renew?
14. Who do I contact when I need support?

Frequently Asked Questions

How long does a credit card transaction take?

The authorization usually happens within seconds. Settlement and funding often take one or two business days, depending on the processor, bank, batch time, and account.

Does an approval mean the business already has the money?

No. Approval means the issuing bank authorized the transaction. The money is transferred later through settlement and funding.

Who pays the credit card processing fee?

The business generally pays the processor, card-network, and interchange-related costs. Under certain pricing programs, the business may structure prices to offset some of those costs.

Why do rewards cards cost more to process?

Premium cards may have higher interchange costs because the issuing bank provides rewards such as cash back, points, or travel benefits.

What is the difference between a processor and a card network?

The processor routes transactions and supports the merchant account. The card network provides the rules and infrastructure connecting the issuing and acquiring sides of the transaction.

What is the difference between authorization and settlement?

Authorization is the approval or decline decision. Settlement is the later process in which the approved transaction is submitted and funds are transferred.

What is a batch?

A batch is a group of approved transactions submitted together for settlement.

Why are online transactions more expensive?

Online transactions generally involve greater fraud and chargeback risk because the card is not physically presented.

What is tokenization?

Tokenization replaces sensitive card data with a substitute token that can be used without storing the full card number.

What is a merchant identification number?

A merchant identification number, often called a MID, helps identify a merchant account within the processing system.

Can a credit card transaction be reversed after approval?

Yes. It may be voided, refunded, disputed, reversed, or charged back depending on the circumstances.

Why did my deposit not match my sales total?

The difference may be caused by processing fees, refunds, chargebacks, reserves, adjustments, net funding, or transactions settling in a different batch.

Final Thoughts

Credit card processing may appear instant, but every transaction involves multiple steps and several participants.

The basic process is:

1. The customer presents a card.
2. The payment information is encrypted.
3. The processor routes the authorization request.
4. The card network sends it to the issuing bank.
5. The bank approves or declines the transaction.
6. The merchant completes the sale.
7. Approved transactions are placed into a batch.
8. The batch is submitted for settlement.
9. Funds are transferred.
10. The merchant receives a deposit.

You do not need to become an expert in payment infrastructure.

However, every business owner should understand enough to know:

• Who handles the transaction
• Why fees are charged
• When deposits should arrive
• Why certain transactions cost more
• How refunds and chargebacks work
• What questions to ask a processor

The more you understand about payment processing, the easier it becomes to protect your margins, improve cash flow, and choose a provider that supports your business.

JadaPay helps business owners accept payments with transparent pricing, dependable technology, and real support from people who understand small business.
