As the payments industry evolves, so does the need for enhanced security and fraud prevention. This article will dive deeper into some of the key security terms and concepts used in payments, particularly focusing on authorization, fraud prevention, and various verification methods.
Authorization
Authorization is a critical process in payment transactions, where the card issuer (such as Visa or MasterCard) verifies the payment details and reserves the necessary funds to complete the transaction. This process involves a series of verifications and risk checks conducted by the payment gateway and processor. Once authorization is complete, the payment can proceed. However, merchants have the option to cancel an authorization if necessary, for instance, if fraud risk is detected.
Bank Identification Number (BIN)
The Bank Identification Number (BIN) is a crucial element in the payments industry. This code, which consists of the first 6 to 8 digits of a card number, is used to identify the card-issuing bank and its card network. By leveraging BIN, merchants can identify card types and enhance transaction security by better managing fraud risks.
Cardholder Verification Method (CVM)
Cardholder Verification Method (CVM) is used to verify that the payment method is being used by the rightful cardholder. This process is particularly important in scenarios such as online payments or mobile payments, where the card is not physically present. The most common CVMs include PINs, signatures, and biometric verification.
