1. The relationship between the signature on the back and the password

In order to ensure the safety of the cardholder's consumption, the signature and password on the back of the credit card are equally important as the "three codes" on the back of the card. As we all know, when using a credit card in China, you usually choose a credit card password, but when using a credit card abroad, you do not need a password and rely entirely on the user's signature. So if the user wants to use the card to make purchases abroad, he must sign on the card.

2. Guaranteed card swallowing accident

I believe that many credit card users have seen or experienced the phenomenon of card swallowing by ATM machines. At this time, the signature on the back is of great use. ! If the identity of the household head cannot be verified, bank staff will confirm the identity through the signature on the back of the bank card and the signature on the registration book, and use this as a basis to handle card refund and other services. However, if the credit card is not signed, the cardholder must bear the loss. It can be seen that there is still a risk without a signature.

3. Backing the signature can prevent fraud

When you swipe your card to make a purchase, the teller will check the signature. If the signature is found to be inconsistent with the signature on the credit card, he has the right to cancel the purchase. If you make a settlement payment without verifying your signature, the risk will be borne by the merchant; however, if your credit card is stolen without a signature, the risk can only be borne by you.
