There is a three-digit credit card verification code on the back of the credit card, which is also a security code. CVC (abbreviated as CVC in English, full name CardVerificationCode) is an additional code printed on the back of a credit card. It is also called CVV (CVV), which is the credit card verification value. It is also called CID, which is the credit card security code or personal security code. All names refer to the same A verification code.

Please note that this verification code does not represent your credit card password. (Generally speaking, credit cards issued domestically have passwords, while credit cards issued abroad do not have passwords). The placement is on the back of the credit card, above the signature in italics. The first 4 characters are the card number, and the last 3 characters are the verification code.

Tips:

When using a credit card, there is a method called "payment without card" or "payment without card". You only need to provide the card number and the stamp on the back of the credit card. The three-digit verification code (CVV, also known as the "last three digits") completes the payment. In addition, people's awareness of the confidentiality of CVV ??codes is quite weak, giving criminals the opportunity to be exploited. Therefore, no matter how tightly protected credit cards and passwords are, they are likely to be stolen.

Therefore, everyone must carefully protect the credit card verification code to avoid being used by criminals.
