1. Suspected cashing leads to freezing.

Frequent use of pos machines to withdraw large amounts of cash leads UnionPay to doubt your credit. The bank will reduce your credit card limit and directly seal the card if the circumstances are serious.

2. Repeated overdue repayment

The solution is to repay in full, call customer service and ask for thawing. In this way, the limit may be lowered, but if the overdue times are not many, the general customer service will unfreeze.

At present, the market is full of second clearing machines. Because some of them adopt the big merchant model, the consumption records of credit cards are in a state of chaos! For example, Zhang San lives in Beijing, and he spent 100 yuan in a store. The registration information of the Qing Er POS machine used by the other party in the bank may be in another city. Once Zhang San spends money on the second-clearing POS machines of other merchants' classes on the same day, if he encounters the same situation, he will have credit card records in several different cities within one day, which is very easy for the bank to monitor and seize.

If the property is frozen or confiscated for various reasons, the credit card will also be frozen. This situation is relatively rare. Solve the lawsuit first and then consider unfreezing the credit card;

6. Once activated, it will be brushed off on the pos machine and easily blocked by the bank.
