Nowadays, more and more people begin to join the credit card team, and basically do not use cash when spending, but pay by swiping the card or through platforms such as WeChat and Alipay. Generally speaking, the credit card has the widest coverage, so there are more people who use it to pay, as long as the credit card is in normal condition. However, some card friends said that their credit card status was normal but could not be used. What happened?

1. The trading environment is abnormal. Credit cards can only be swiped in an environment that supports credit card payment, such as POS machines. If the merchant's receipt code enables the credit card collection function, you can also scan the merchant's receipt code and use a credit card sub-card. On the other hand, if the trading environment does not support credit card spending, then it is naturally impossible to pay by credit card. Moreover, credit card transactions are monitored by the banking system. If the banking system monitors the risks in the trading environment, it will not support credit card swiping.

2. Card swiping skills. If the cardholder spends his credit card through the POS machine, then there is a limit to the transaction of the POS machine. If the transaction of the POS machine reaches the limit on the same day, it will be impossible to continue spending by swiping the card. Therefore, if the POS machine reaches the limit, the credit card will be normal but cannot be traded. In addition, if the flow card of the POS machine has no flow, it can't be swiped normally.

3. Transaction amount. A credit card has a credit line. When a cardholder uses a credit card to spend money, the available credit line cannot be lower than that of a single transaction. If the credit limit of the credit card is insufficient, then even if the credit card is in a normal state, it can't be used normally. In addition, if the cardholder sets himself a credit card limit, he can't overdraw after reaching the limit.

4. transaction password. You need to enter a transaction password when you use a credit card. If the cardholder accidentally enters the wrong password, it will lead to the failure of swiping the card. If the credit card password is entered incorrectly for three consecutive times, the credit card will be locked. At this time, everyone needs to unlock it before they can continue to use the credit card to spend money.

These are the reasons why you can't swipe your credit card when it is normal. If you don't know why your credit card can't be swiped, you can call the bank's customer service hotline for consultation.
