The signature on the back of the card, like the password of the card, also protects the interests and safety of the owner. Especially when the card is lost, it is very important to check the signature.

Many credit cards don't have passwords, so signature is more important. Because responsible consumers will determine whether the user is a cardholder according to the signature of the certificate, if the credit card is lost and the name and signature are not affixed on the back of the card, it will be easily detected.

Precautions:

Sign in in time. Upon receipt of the bank card, you should immediately sign the signature strip on the back of the card.

When spending by credit card, when handing over the bank card to the cashier, you should try to put the bank card in your sight, pay attention to the number of times the cashier swipes the card, whether there are two overlapping purchase orders, and carefully check whether the amount and currency on the purchase orders are wrong.

Don't always carry all kinds of bank cards with you, leave them at home when not in use, and store them in other safe places when not at home for a long time.
