1. Signature+password verification
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 must be borne by the consumer.

The advantage of only using signature verification is that the merchant has the responsibility to verify the signature, and the bank also has to bear the compensation responsibility for the theft of the credit card, so once the credit card is stolen, the consumer can get compensation from the bank or the merchant, and at the same time, because the password is not needed, the consumer also saves the trouble of forgetting the password and not spending. The disadvantage is that due to the imperfect signature verification technology in China, once the credit card is lost, there is a great risk of being stolen.
Signature and password are two kinds of security means, and both can be used. There are many signatures abroad, and the password is the first choice in China. Both methods have advantages and disadvantages.
