When using a credit card to spend money, the bank will need to verify the identity of the cardholder, and there are two main ways to verify the consumption, one is signature, and the other is this "password plus signature". That is to say, if you set a transaction password when applying for a credit card and sign on the back of the card, you must enter this transaction password and sign the shopping list when swiping the card to complete the consumption.

The advantage of "signature+password" verification is that the security is higher than that of using signature alone, and the risk of credit card being lost and stolen is very small. The disadvantage is that once the credit card is stolen, the consumer will take full responsibility, and the bank that reported the loss will no longer be liable for compensation.

Note: This method is mainly based on password verification. Once the cardholder's password is correct, even if the signature does not match, the loss of stolen brush will be borne by the consumer.

Is password+signature safe?

Bankers said that it should be treated separately according to the card environment and the type of credit card used. For example, the foreign credit card market is relatively mature, and there is no need to set a password. However, in China, not all banks' credit cards are not guaranteed, and cardholders should still set transaction passwords. For credit cards without card protection, the cardholder can choose not to set a password.
