How Card Processing Works: The Main Players

How Card Processing Works: The Main Players

The key players involved in settlement and authorization are the cardholder, the merchant bank, the processing bank, the acquiring bank, the issuing bank and the card associations, aka Visa and Mastercard cardholder.

Technically speaking, any business that sells its good or services is a merchant. However, in this instance, only merchants that accept card payments are our focus. Therefore, a merchant is any business that accepts card payments from cardholders in exchange for its goods and services. As a business owner, you are also a merchant.

Merchant’s Bank

A bank that is registered and an official partner of the card associations such as MasterCard and Visa is an acquiring bank that is often called a merchant bank as they manage the business accounts of the merchants or businesses, and allow them to accept debit and credit payments.

Merchant banks also provide businesses with software and devices to accept card payments and manage customer service along with other essential aspects involved in accepting card payments. These merchant banks even deposit funds from the card sales into the business owner’s account.

Surprisingly enough, many businesses don’t recognize their merchant bank as the leading provider of their merchant account. Merchant banks are playing an increasingly crucial role as the bankcard systems are evolving. Merchant banks sometimes enlist the assistance of a third party independent sales organization to conduct and evaluate the daily activities of their business accounts.

Payment processors enable merchants or business owners to receiver their credit and debit card processing payments online by connecting to an acquiring bank

Payment Processors

Payment processors enable merchants or business owners to receiver their credit and debit card processing payments online by connecting to an acquiring bank. The processors perform many other essential functions, such as ensuring the authenticity of the transactions, implementing anti-fraud measures to provide all the purchases initiated by sources that are valid.

Processes follow standard rules and regulations set by their registered credit card association.
These rules are regarding identity theft, fraud, and chargebacks. If any buyer has used a debit or a credit card to place their order with the merchant, the payment will transfer transaction details from gateway to the relevant card association.

Issuing Bank

As you’ve probably guessed, an issuing bank issues credit cards to consumers. The issuing bank is also a member of the card associations (Visa and MasterCard). Issuing banks pay to acquire banks for purchases that their cardholders make. It is then the cardholder’s responsibility to repay their issuing bank under the terms of their credit card agreement.

Card Association Companies (Visa and MasterCard)

MasterCard and Visa are not banks, and neither do they issue merchant accounts or credit cards. They are just custodians for their card brand. They also operate as the official governing body of financial institutions. They work together with MSPs and ISOs to support and facilitate electronic and credit card processing. Hence their title, “card associations.”

The primary responsibilities of the card associations are to monitor and govern the members of their associations, including qualification guidelines, interchange fees, and to act as an arbiter between acquiring banks to improve the card network, to maintain it, and to make a profit.
