CCV, the full name is Card Verification Value, the Chinese name is card verification value, which is the three-digit code on the bank card. The purpose of this code is to verify whether the cardholder is the authorized user of the card. Usually, CCV codes only exist on credit cards, but not necessarily on debit cards.

The CCV code is one of the information that must be provided when shopping online. Only by entering this code correctly can the transaction be successfully completed. This can avoid the risk of credit card theft and improve consumer safety. Moreover, the CCV code is also a means for banks to verify identity when conducting remote transactions.

In order to avoid malicious theft of credit cards, cardholders must pay attention to protecting their CCV codes when using credit cards. When using a credit card, avoid sharing your credit card-related information with others, including credit card number and CCV code. Never tell others your credit card number and CCV code easily, and do not conduct credit card transactions in an unsafe network environment to ensure the safety of your funds.
