When applying for a credit card, users can choose "signature+password" or "signature" when swiping the card. If "Signature" is selected, the consumer can complete the transaction without entering a password after swiping the card.
You can complete the transaction by swiping a credit card without entering a password. Once the credit card is lost, the money in the card is easily stolen, which is a security risk for the cardholder.

"Signature" and "password+signature" are two main means of credit card transaction verification at present. Whether a credit card should have a transaction password and the responsibility determination after being stolen are controversial topics for many years.
Because the cardholder is responsible for keeping the password after setting the transaction password, if the cardholder reveals the password to a third party, including entering the password on the phishing website, the cardholder will bear the debt, which leads many consumers to hesitate whether to set the password on the credit card.
Bank of Communications credit card experts pointed out that in the domestic payment environment, setting transaction password plus signature verification is obviously safer than simple signature verification. Because the task of checking whether the signature on the purchase order is consistent with the signature on the back of the card is completed by the merchants on the spot, but now many domestic merchants are sloppy in checking the signature, and the signature is easy to forge, but it is difficult to tell the difference with the naked eye.
Password is a verification tool that only I know, and it is not easy for others to get it. One more verification link, one more guarantee. This means that "password+signature" verification is much safer than simple "signature" verification. As long as the cardholder pays attention to protecting personal information such as passwords, the probability of "stealing brushes" will be greatly reduced.
