There are several reasons why credit cards are stopped:

1. Suspected cashing leads to freezing;

2. Overdue repayment for many times;

3. Code set and code jump of the second clearing POS machine: At present, the second clearing machines are flooding in the market, and some of them use the big merchant model, which leads to the chaotic consumption records of credit cards! For example, if Zhang San lives in Beijing, he spends a transaction in 1 yuan in a certain store, and the registration information of the Erqing 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 machine in other merchants' classes on the same day, if he encounters the same situation, there will be a credit card swiping record in several different cities within one day, which is very easy to be monitored and seized by the bank.
