If it is a non-Quick Pass POS machine, you can only insert and swipe the card in the traditional way, which requires a password to make transactions. Transaction amount: In order to prevent transaction risks, only small transactions of less than 1,000 yuan can be paid without a password. For transactions exceeding 1,000 yuan, even if Quick Pass is available, a password must be entered before the card can be swiped.

Credit card swiping generally requires entering a password, but there are some that do not require entering a password but require a signature. Small-amount password-free and visa-free: It is a small-amount fast payment service provided by China UnionPay for UnionPay IC cards with the "Quick Pass" function. Customers do not need to activate it separately.

Specifically, the credit card must be a card that the cardholder has accepted for use, the unauthorized use occurs before the cardholder notifies the card issuer, the card must be lost, stolen or other similar acts , has been or may have been used without authorization.

As can be seen from the above introduction, credit cards can be used without passwords, and transactions are mainly based on signatures. It should be noted that there are certain risks in transactions based on signatures, especially if the credit card is lost and easily stolen by others. After all, most shopping malls will not seriously verify consumer signatures.
