1. When citizens swipe their cards in shopping malls, cashiers in many shopping malls have to check the signatures of consumption documents with the handwriting on the back of bank cards or credit cards to see if they are consistent.

2. At the same time, when citizens withdraw money from the ATM of the bank, if there is something wrong with the machine and the card is swallowed, the bank staff can also check the signature on the back of the bank card with the signature on the register if they can't verify the identity of the owner, so as to handle the card refund business.

In addition, once the bank card is stolen, the signature and handwriting will also help to prove that it is not the person who swiped the card.

Pay attention to the use of bank cards

1. When spending by credit card, when handing over the bank card to the cashier, try to keep the bank card within your sight, and 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.

Try not to lend your bank card to others, especially credit cards, and pay more attention.

3. After using telephone banking, please remember to take off the receiver again and dial a bunch of money casually, and then hang up to avoid the bank card information and password being redialed by others.

When you forget your password, remember not to enter it more than three times, and it will be locked, so you can only take your ID card to the bank to unlock it.

Phoenix. Com- the name of the cardholder should be filled in the signature column of the bank card.
