What is card processing?

Card processing refers to the set of procedures and technologies that enable businesses to accept payments made with credit or debit cards. It involves securely capturing card information, verifying funds, authorizing transactions, and transferring money from the cardholder's account to the merchant's account. Card processing typically includes both in-person transactions with physical card readers and online payments via payment gateways. This process is essential for modern commerce, ensuring fast, secure, and convenient payments for both customers and businesses.
