There must be a signature on the back of the credit card. This signature is equally important as the password.

For consumers, although credit cards have passwords, as the number of credit card uses increases, the risk of password leakage also increases. After the credit card and password are lost, checking the signature on the back of the credit card becomes the last barrier to protect the cardholder's credit card security.

If the cashier finds that the signature does not match the signature on the credit card during the signature verification process, he has the right to cancel the purchase and refuse to sell the goods, which to a certain extent avoids the loss of the owner of the goods.

Bankers remind cardholders that when applying for a credit card, they should sign a more personalized name, preferably a signature that is difficult to imitate. At the same time, consumers should not set passwords to easily testable numbers such as birthdays.

In addition, you should develop the habit of retaining transaction documents to facilitate reconciliation. When problems arise, provide bank investigation. It is best to remember the bank phone number. If you find that the card is lost or stolen, call and report the loss immediately. .
