Bank card CVC refers to the credit card security code, which is usually displayed in italics at the top of the signature on the back of the card. The first four digits are the card number, and the last three digits are the verification code, that is, the last three digits. When using it, bind the credit card in your name to the online trading platform. While verifying the mobile phone number, enter the CVC code of the credit card, which is the last three digits on the back. Every time you change your credit card, the credit card security code will also change.

A credit card is a credit card issued by major commercial banks to qualified consumers. Consumers holding credit cards can go to specialized commercial service departments for shopping and overdraft within the prescribed limit. Finally, the bank will settle the accounts with merchants and cardholders.

If the credit card is lost, please report the loss as soon as possible, because if the person who picked up the bank card knows the mobile phone number and the CVC code, it is very dangerous. If the verification code is leaked, then Credit cards are at risk of being stolen. If you use a credit card for online shopping, remember to protect the last three digits, because on some online shopping websites, credit card payment can be completed without entering a password.

Do not make late repayments on credit cards for daily use, because late repayments will generate penalty interest, and the longer the time, the more penalty interest will be generated. Moreover, after the penalty interest is generated, the bank will collect the money. A common method of collection is to call the cardholder. It should be noted that overdue credit card repayment will affect the personal credit report.
