Credit card freezing means that your credit card is frozen by the bank due to risk control and other reasons, so you can't conduct activities such as consumption and trading. Generally speaking, credit cards are blocked because banks consider credit cards as "high-risk credit cards", so what card use behavior may lead banks to make such a determination?

Credit card seal red line:

1. Anyone who submits information through an intermediary will be directly blocked as long as there is suspicion.

2. Repeat the operation on the same POS machine for several months.

3. The credit limit of a card is 10000. Once activated, it will be swiped off the pos machine.

4. swipe the same card on the same capping machine on a fixed date every month, occupying bank funds.

5. There are transactions outside normal business hours, such as after-hours transactions of merchants in wholesale markets.

6. Too many people pay with Alipay in a short period of time, such as CITIC's single highest 1000, multiple transactions 99899589999 and other similar figures.

7. The credit card has been empty for a long time. For example, it takes a short time to enter the whole number on the repayment date, and the whole number comes out. At other times, there is no credit card record, and the number of times is less than 2 times. It can be found out by operating the background system for several months.

8. It's best to sign in person, not on your behalf. If you change the bill, people will find that your receipt was signed by the same person. Even if you are doing business normally, he will think you are helping others. At the same time, it is best to keep the receipt for more than half a year.

The most important point is that credit cards will be invalid for various reasons. It is often found that car owners can't brush like this, 10000 can't brush, and 9950 can't brush. 9800 can't be brushed, and 9500 can't be brushed. This operation will continue until the credit card is successfully swiped. This is the biggest risk and will be immediately recognized as TX by the system. Remember, most transactions will fail.

How to release a blocked card:

If there is evidence that the cash is not cashed out by itself, but there is something wrong with the POS machine of the merchant, the credit card center may also unseal it. At this time, the bank may ask the cardholder to provide a small ticket or recall the credit card. Therefore, it is best for cardholders to keep a record of each "consumption". If you have a receipt, keep the receipt (or invoice) for the bank to check. The bank will unfreeze you after verification. If the card is stolen, you must contact the bank for freezing as soon as possible. After that, the issuing bank will help cancel the customer's card and issue a new card to the customer. At the same time, check whether the funds have been cleared from the issuing bank. If not, it will be intercepted. So don't worry this time. If you are accidentally injured by the bank, it is recommended to contact the customer service of the bank as soon as possible, submit the relevant proof and explanation of normal consumption, and unfreeze the credit card as soon as possible.
