The card number validation process is crucial for securing online transactions and preventing fraud. It ensures that the card being used is legitimate and has not been reported lost or stolen.
The Luhn algorithm, also known as the 'modulus 10' or 'mod 10' algorithm, is the first step in card number validation. It checks the card number for mathematical accuracy.
The Issuer Identification Number (IIN), also known as the Bank Identification Number (BIN), is the first six digits of the card number. It identifies the issuing financial institution.
The Cardholder Verification Value (CVV) is a three- or four-digit number on the back of the card. It is used to verify that the card is in the possession of the legitimate cardholder.
The expiry date on the card is used to ensure that the card is still valid. Transactions will not be processed if the card has expired.
Understanding the card number validation process is essential for both businesses and consumers to ensure secure and legitimate transactions.
