The CVV (Card Verification Value) is a three or four-digit number printed on the back of a credit or debit card. It is used as an additional security feature for online transactions. The CVV is not the same as the PIN (Personal Identification Number) and is used specifically for online or over-the-phone payments. It is designed to prove that the cardholder has the physical card in their possession, thus reducing the risk of fraud. The CVV is unique to each card and is not stored in the magnetic strip, making it essential for completing online transactions securely.
In summary, the CVV is a crucial security feature that helps protect cardholders from unauthorized transactions when making purchases online or over the phone.
