Because there are two ways to verify credit cards, some bank cards have no passwords.

1. signature.

under this setting, no password is required for consumption. In case of stolen credit card, you can ask the merchant to sign the bill and identify the person who swiped the card by signature, and ask for refusal or refund. The premise is that you have relevant copies or photos, record your credit card and then sign the pattern for comparative evidence.

2. Password.

The bank says that the consumer password is optional, but at the same time it says that password transactions are regarded as personal transactions. That is to say, as long as the password is used, in case someone reads it, it is regarded as your own brush to make a fake card or steal your card with the password. Banks and businesses are irresponsible.

At present, credit cards with passwords in China include CCB, ICBC and Minsheng.

Credit cards without passwords include Guangfa and China Merchants.

Bank card refers to a credit payment tool issued by commercial banks (including postal financial institutions) with all or part of the functions of consumer credit, transfer settlement, cash deposit and withdrawal. Bank card reduces the circulation of cash and checks, which makes the banking business break through the limitation of time and space and undergo fundamental changes. The application of bank card automatic settlement system will make a "no check, no cash society" become a reality.
