Because there are two credit card verification methods, some bank cards do not have passwords.

1. Signature.

Under this setting, no password is required for consumption. If fraud occurs, you can ask the merchant to adjust the bill and use the signature to identify someone else who swiped the card, and request a refusal or refund. The premise is that you keep relevant copies or photos, and record your credit card signature style as evidence for comparison.

2. Password.

The bank’s statement is that the consumption password is optional, but at the same time it also says that password transactions are regarded as personal transactions. In other words, as long as you use the password, if someone else sees it, forges the card or steals your card and uses the password, it will be regarded as you swiping the card yourself. Banks and merchants are not responsible.

Currently, credit cards with passwords in China include China Construction Bank, ICBC, Minsheng Bank, etc.;

Credit cards without passwords include Guangfa, China Merchants, etc.

Bank cards refer to credit payment instruments issued to the public by approved commercial banks (including postal financial institutions) with all or part of the functions of consumer credit, transfer settlement, cash deposits and withdrawals, etc. Bank cards reduce the circulation of cash and checks, allowing banking business to break through the limitations of time and space and undergo fundamental changes. The application of the bank card automatic settlement system will make a "checkless, cashless society" a reality.
