Credit cards are suspended for several reasons:

1, suspected of cashing out and causing freezing;

2. Repeated overdue repayment;

3, second-clearing POS machine code set, code jump: At present, the market is full of second-clearing machines, and some of them adopt the big merchant model, resulting in a chaotic state of credit card consumption records! 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.
