A Quick History of Credit Card Processing
The concept of credit cards began in the 1920s with “courtesy cards” used by large U.S. businesses (like hotel chains and oil companies) to allow customers to charge purchases at their stores.
In 1950, Diners Club introduced the first credit card that could be used at multiple locations. Frank McNamara, who forgot his wallet at a restaurant, came up with the idea that launched this multi-store card. By 1951, 20,000 people held Diners Club cards.
American Express introduced a charge card in 1958. Later that year, Bank of America launched the Bank America —the first revolving credit card that allowed consumers to carry a balance.
In 1976, Bank America became Visa, and Master Charge became MasterCard. The credit card industry grew rapidly, and consumer protections followed, like the Truth in Lending Act (1968) and the Fair Credit Reporting Act (1970).
The 1980s brought cash-back rewards with Discover. In 2009, the CARD Act limited penalties and fees on credit cards.
Today, Visa and MasterCard operate some of the largest card networks in the world.`

How Credit Card Processing Works
Each card transaction involves several key players:
- Cardholder – The customer using a credit card
- Merchant – The business accepting the payment
- Acquiring Bank – The merchant’s bank that processes credit card transactions
- Issuing Bank – The customer’s bank that issued the credit card
- Credit Card Networks – Visa, Mastercard, Discover, American Express
- ISOs and MSPs – Third-party processors and merchant service providers
Transaction Flow:
- Authorization:
The cardholder initiates a payment, and the merchant transmits the data via a payment gateway to the processor/acquiring bank. It goes through the card network to the issuing bank. - Approval:
The issuing bank verifies the transaction, checks for fraud, and sends approval/denial back through the network to the merchant. - Batching:
At the end of the business day, the merchant submits all approved authorizations as a batch. - Settlement:
The issuing bank sends funds (minus fees) through the network to the acquiring bank, which deposits them into the merchant’s account.
Payment Terms to Know
- Card Not Present (CNP): Online or phone transactions without a physical card
- Chargeback: Disputed transaction reversed by the issuing bank
- Interchange Fee: Charged by the card network and paid by the merchant
- Merchant Discount Rate: Total percentage taken from each transaction
- Payment Gateway: Software that transmits transaction info securely
Credit Card Compliance
Merchants must follow security rules known as PCI DSS (Payment Card Industry Data Security Standards), developed by the PCI Security Standards Council.
Your compliance obligations depend on:
- Transaction volume
- Whether you store cardholder data
- Tools and software you use
Choosing a PCI Level 1 Compliant Provider like The Cable Team simplifies compliance and reduces risk.
Additional Legal Requirements
If you accept debit cards and ACH payments, you must comply with:
- The Electronic Funds Transfer Act (EFTA)
- Regulation E, which requires written and signed authorization for each debit
These apply even for one-time transactions.
Understanding Credit Card Processing Fees
Fees vary depending on your provider, card network, transaction method, and your contract terms.
Common Fees Include:
- Interchange & Network Fees
- Monthly Statement Fees
- PCI Compliance or Non-Compliance Fees
- Address Verification (AVS) Fees
- Chargeback & Retrieval Fees
- NSF (Insufficient Funds) Fees
- Early Termination Fees
Pricing Models:
- Interchange-Plus: You pay actual interchange cost + a fixed markup. Transparent and itemized.
- Tiered Pricing: Bundles transactions into Qualified, Mid-Qualified, and Non-Qualified groups. Less transparent.
- Zero-Cost Processing: You pass transaction fees to the customer (legal review recommended).
