1. Just place the card or mobile device close to the "Quick Pass" sensing area of ??the POS machine and other acceptance terminals and "swipe the card" to complete the payment. During the payment process, the cardholder will not be asked to enter a password or sign.

2. Pay with "password signature": If a password is set on the credit card, you need to enter the password when swiping the card. If the password is incorrect, the transaction will not be successful. Pay with "signature": If the credit card does not have a password set, you do not need to enter the password when swiping the card, but the cashier needs to check the cardholder's signature handwriting.

3. The reason why credit card swiping does not require a password is as follows: Anyone who knows about credit cards knows that credit card payments in the United States can usually be completed with a signature. After the introduction of credit cards in China, credit cards also require a signature. Consumption is brought into the country. Many people consider avoiding password transactions and signing with a single stroke of a pen as "fashionable".

4. When swiping a bank card with Quick Pass enabled, the single amount does not exceed 1,000 yuan, and there is no need to enter a password or signature. Only on contactless payment terminals that support UnionPay "Quick Pass", Pay quickly with just one swipe.

5. There is no need to enter a password when swiping a card. This black technology from UnionPay is called password-free and visa-free for small amounts. Small-amount password-free and visa-free is a small-amount fast payment service provided by China UnionPay to cardholders.

6. Why can I suddenly swipe my credit card without entering the password? There are two situations, one is a signature-based transaction, and the other is a small-amount double-free transaction.
