Visa credit card verification helps to protect consumers and merchants against fraud, notes Visa. It adds an extra layer of security to prevent the use of the card in the event the account number or card is stolen.
Visa card verification works by requesting additional password or data to confirm a person's identity, states Visa. A Visa card user must enroll in the program by creating an account and a Verified by Visa password. This can be done on the card issuer's website or by creating a password when prompted during the checkout process. Online transactions can only be completed after a successful authentication.
