Bank staff said that the signature on the back of the credit card is the guarantee of consumer safety and is as important as the password. Unlike in China, you don't need to verify the password when you spend your credit card abroad, but you rely entirely on your signature. Therefore, if the cardholder does not sign back, it will affect his normal consumption abroad.
With the signature on the back of the credit card, you can get back the card swallowed by ATM.
When the cardholder withdraws money from the ATM of the bank, if the machine breaks down 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 under the condition that the identity of the victim cannot be verified, so as to handle the card return business.
If the signature on the back of the credit card doesn't match, the mall can refuse to sell the goods.
When spending by credit card, the cashier has the right to cancel the consumption and refuse to sell the goods if he finds that the signature does not match the signature on the credit card during the process of checking the signature. Don't think this is a fantasy, because the risk of credit card theft caused by unsigned settlement will be borne by the merchant, and the responsibility for the theft of unsigned credit cards lies with the cardholder.
So the signature on the back of a credit card is very important, but many people tend to ignore its importance. Regarding the back signature, you need to pay attention to the following two points:
The font of the signature on the back of the credit card should be consistent with the usual signature. Try to avoid too neat fonts, otherwise it is easy to be imitated.
The credit card signature cannot be altered, otherwise the signature is invalid. If you accidentally sign the wrong card, you can apply to the bank for a new card. In addition, it is best to use a ballpoint pen when signing. When the pen and ink are dry, put the card back in your wallet to prevent the signature from being blurred.
