Bank of Communications credit card verification code refers to the three digits on the back of the card.
On the back of each credit card, two sets of numbers are usually displayed in italics at the top of the signature. The first four digits are the last four digits of the card number. The last three digits are commonly known as "the last three digits". It is a verification code set by commercial banks to ensure the security of credit card passwords, and it is used for indirect credit card consumption transactions for bank cards. For example, online payment and other transactions, so the "last three yards" of the credit card cannot be leaked.
Bian Xiao reminded that in addition to passwords, credit card numbers, credit card expiration dates, credit card use verification codes CVV2 (the last three codes) and ID numbers are also extremely important personal information, which can be used for remote non-face-to-face transactions such as air tickets, business trips and hotel reservations, and should not be easily disclosed.
Be extra careful when asking for a transfer or password from a strange phone. When making online payment, cardholders should ensure that transactions are made on the websites of well-known companies and reputable third-party payment platforms, avoid using online banking in public places and leaving personal information on computers, and do not open any web pages.
