Understanding Card Verification
Card verification is a crucial process for ensuring the authenticity and security of credit card transactions. It involves several steps that merchants and financial institutions follow to confirm the validity of a card before authorizing a transaction.
Initial Verification
The first step in card verification is to check the card's expiration date and ensure that it is still valid. This helps prevent the use of expired cards.

Card Security Code Check
Next, the card security code (CSV or CVV) is verified. This three or four-digit number is located on the back of the card and is used to prevent unauthorized use.
Address Verification System (AVS)
The AVS checks the billing address provided by the cardholder against the address on file with the card issuer. This helps to ensure that the person making the purchase is the legitimate cardholder.
Cardholder Authentication Protocol (3D Secure)
The 3D Secure protocol adds an additional layer of security by requiring cardholders to enter a password or PIN during the transaction process.
