2. For consumers, although all credit cards have passwords, the risk of password leakage increases with the increase of credit card usage. After the credit card and password are lost, checking the signature behind the credit card becomes the last barrier to protect the security of the main credit card.
3. If the cashier finds that the signature does not match the signature on the credit card in the process of checking the signature, he has the right to cancel the consumption and refuse to sell the goods, which can avoid the loss of the owner to a certain extent.
Bankers remind that for cardholders, when handling credit cards, they should sign a more personalized name, preferably a signature that is difficult to imitate. At the same time, consumers should never set their passwords to easy-to-try numbers, such as birthdays.
5. In addition, it is necessary to develop the habit of saving transaction documents to facilitate reconciliation and provide them to the bank for investigation when problems arise. It's best to memorize the telephone number of the bank. Once the card is found to be lost or stolen, report the loss by phone immediately.
