1. Advantages of Credit Card Quick Pass Function Credit Card Quick Pass is a contactless payment application, which has the advantages of fast payment and no password for small amounts. However, Quick Pass can only be carried out under two conditions. One is a credit card with Quick Pass function, that is, a Quick Pass credit card; the other is a UnionPay POS machine with a Quick Pass logo. Both conditions must be met at the same time, otherwise Quick Pass cannot be processed.
2. How to tell whether a credit card has a quick pass function can mainly be judged from the card surface. Observe three points: 1. Credit card type: Credit cards are divided into magnetic stripe cards and IC cards. Only IC cards have quick pass functions. There is no payment function in magnetic stripe cards. These two types of credit cards can be judged from the card swiping method. IC cards are inserted into the card slot on POS machines for transactions, and magnetic stripe cards are swiped in the card slot. 2. Credit card logo: Quick Pass credit cards are marked on the card, usually with "Quick" on the back of the card, indicating quick transactions. 3. Credit card organization: Quick Pass is a function of UnionPay. Only UnionPay cards have Quick Pass function. Visa and MasterCard do not have it. UnionPay cards all start with 62 and have the word UnionPay on the card. In fact, Quick Pass is not only possible with Quick Pass credit cards. Non-Quick Pass cards can also be realized with the help of NFC-enabled mobile devices. However, it should be noted that credit card Quick Pass is enabled by default for small amounts without password and signature. Even if Transactions are based on passwords. As long as the amount of a single card swipe is less than 1,000 yuan, transactions can be made without a password. Friends who mind can choose to turn off the double-free function.
