Key Components of Card Processing

Credit card processing involves several components that work together. Here is an overview of the main players involved:

Cardholder

The cardholder is the customer who owns a credit card issued by a bank or financial institution.

Merchant

The merchant is the business or individual that sells goods or services and accepts credit card payments.

Acquiring bank

The acquiring bank, or acquirer, is the financial institution that partners with the business to process credit card transactions. The acquiring bank receives transaction information from the business and communicates with the issuing bank to obtain authorization.

Issuing bank

The issuing bank, or issuer, is the bank or financial institution that issues the credit card to the cardholder. The issuing bank approves or declines transactions based on factors such as the cardholder’s available credit and account status.

Card networks

Card networks are organizations—such as Visa, Mastercard, American Express, and Discover—that provide the infrastructure and rules for processing credit card transactions. Card networks act as intermediaries between acquiring banks and issuing banks to facilitate transaction communication, authorization, and settlement.

Payment gateway

A payment gateway is a tool that transmits payment information from the business’s point-of-sale (POS) system or ecommerce platform to the acquiring bank for processing. It encrypts the cardholder’s data and ensures the transaction complies with security standards.

Payment processor

A payment processor, or payment processing provider, is a company that manages the transaction process on behalf of the acquiring bank, handling tasks such as communicating with payment networks, obtaining authorization, and managing the settlement process.

POS system

A POS system is the hardware and software businesses use to accept credit card payments. For in-person payments, this might include a card reader or a retail terminal. For online transactions, this would include the e-commerce platform and payment gateway.

These parties ensure that credit card transactions are secure and efficient and comply with regulations and industry standards, providing an easy and fast payment experience for customers and businesses.
