1. The channel for handling the card is abnormal: if the cardholder handles the credit card through a black intermediary or a private agent, it is very likely that the card will be blocked by the bank because of the suspicion of cheating the card.

2. The card swiping method is abnormal: for example, a credit card often swipes the card on the same POS machine; There are transactions beyond normal business hours, such as after-hours transactions of merchants in the wholesale market; The transaction amounts are all integers or straight, such as 1,5, 666,8888, etc., which will easily trigger the bank's risk control system.

3. Long-term empty: Empty the credit card for a long time, return it on the repayment date, and then get it out, which is often maxed out. The bank's risk control system will definitely focus on you, because this is a very obvious cash-out behavior.

If you don't know exactly what caused the card to stop, you can get a credit card risk report from Kayouchali. This WeChat will conduct risk detection on the cardholder's consumption behavior and transaction behavior, and help you find the real reason for the card blocking.

if the card is blocked because of the risk of the account, you can bring all the relevant proof materials to the issuing bank and submit your personal identity certificate. After being authenticated by the bank, you can apply for a password change, re-opening or cancellation and re-applying for a new card, and it will take about 1-3 working days to resume use.
