Reasons why credit cards can't be swiped when there is a limit:
1. Card swiping is restricted.
If there is a limit in the credit card but you can't swipe it, then it may be that the credit card is restricted.
For example, if you set a daily limit for your credit card, you can't swipe your card after spending reaches the limit that day, even if there is still a limit in your card.
Or the number of swipes in a day is too frequent, which will also be restricted, resulting in the inability to swipe even if there is a quota inside.
2. The card is frozen
If the card is abnormal, such as being frozen by the bank, you can't swipe it even if there is a limit in your card.
3. The transaction is risky.
If your credit card transaction is suspected to be risky by the bank, the bank will not let you successfully trade in order to avoid the risk.
For example, some people use the card improperly, which leads the bank to suspect that you are cashing in when you trade, so you can't trade, which leads to the limit in the card but you can't swipe it.

Use problem
security issue
Due to the convenience and rapidity of using credit cards, coupled with the rapid development of science and technology, the security problems faced by credit cards are becoming more and more serious, and major international credit card groups and global card-issuing financial institutions are facing severe challenges. The security problems of credit cards are mainly divided into the following five aspects:
1. credit card: criminals or criminal groups use forged or invalid cards (expired/lost/invalid/damaged tapes, etc. ) pretending to be a real card, directly deceiving merchants or card issuers.
2. Cardholder: improper storage/handling of cards (expired/invalid credit cards are not destroyed, or they are not immediately invalidated after being lost, etc. ), and personal identity information is inadvertently stolen or defrauded. In order to avoid such problems, citizens should not easily provide personal identification information, and it is best not to entrust others to handle credit cards.
3. Consumer merchants: the service personnel have overspent in the cardholder's consumption process, or embezzled his credit card information to other merchants for consumption. This situation can happen whether it is a physical business or a network virtual business.
4. Issuer: The computer system is maliciously invaded, stealing the basic/transaction information of customers. There are also some unscrupulous cases in which employees in the organization are in the house, stealing from themselves or working in the house.
5. Trading system and mechanism: As long as it is formulated or handled by human beings, human errors and omissions will inevitably occur; No matter how rigorous the trading mechanism is, with the world-class trading system from confirmation to settlement, it is still possible to be invaded, and the so-called "invasion" is actually divided into levels.
