In order to protect against credit card fraud, a CVV number, or Card Verification Value is printed on the back of the card. It is a three or four digit security code printed on credit cards, intended to guard against identity theft in transactions where the actual card is not present.
CVV1 Code
There is another, less known code also present on the card called the “CVV1” code. This is encoded on the magnetic strip of the credit card hidden from view. CVV1 is used for security on transactions when the cardholder is present in person.
