A credit card is a credit service provided by the card-issuing bank to cardholders. Credit card holders can obtain a certain credit limit, which can be used for daily consumption. For cardholders who use their credit cards well, the bank will increase their credit limit. For cardholders who use their credit cards improperly, banks will often block their cards. So what behaviors will cause card holders to have their cards blocked when using their credit cards?

1. If you frequently make late payments, the bank will conduct risk control and block your card.

2. If you swipe your card at a POS machine with code hopping or code hopping, it is easy to be blocked by bank monitoring.

3. When applying for a credit card, if the information is submitted through an intermediary, the bank will directly block the card if it is discovered.

4. If the same credit card has transactions on two or more terminals within half an hour, the card will be blocked if detected.

5. The card will be blocked when there are abnormal transactions, such as transactions still occurring after normal business hours.

It is worth noting that if the situation is serious, you will be included in the bank's blacklist and you will not be able to handle any loan business with this bank in the future.
