When using a credit card, you need to add a security protection device to the credit card. The "signature + password" consumption verification method is this security protection device, which is a way for the bank to confirm the cardholder's identity when making purchases. At present, there are two main consumption verification methods: "signature" and "signature + password". Cardholders can choose any verification method. The advantages and disadvantages are:

1. Signature + password verification

The advantage of "signature + password" verification is that it is more secure than using a signature alone. Once the credit card is lost, the risk of it being swiped is very small. The disadvantage is that once the credit card is stolen, the consumer will bear full responsibility, and the bank will no longer be liable for compensation.

Note: This method is mainly based on password verification. Once the password of the card swiper is correct, even if the signature does not match, the consumer will be fully responsible for the loss of the stolen card.

2. Signature

The advantage of using only signature verification is that the merchant is responsible for verifying the signature, and the bank is also responsible for compensation if the credit card is stolen. Therefore, once the credit card is stolen, consumption The user can obtain compensation from the bank or merchant. At the same time, because no password is required, consumers also save themselves the trouble of forgetting the password and being unable to consume. The disadvantage is that because my country's signature verification technology is not yet perfect, the risk of credit card being stolen is very high.

Note: After being stolen using this method, if the consumer fails to report the loss within the specified time, he will need to bear the relevant losses. Since the bank also needs to collect evidence and verify the fraudulent use, it will take a certain amount of time for consumers to make claims.

Both security protection devices have certain security risks. "Signature + Password" is a safer security protection device than "signature". When using a credit card, in addition to the security protection device set up by the bank, you must also manage your own card to prevent loss and report the loss promptly.
