Whether the credit cards of fans of China Everbright Bank will suddenly be blocked depends on the usage of the cardholders. In general, the following reasons will cause sudden jamming.

Reason 1: If the credit card is overdue for more than three periods, the bank will charge interest and late fees to the cardholders who have overdue repayment. When overdue occurs for many times or the overdue amount reaches a certain amount, the bank will think that the cardholder has malicious overdraft consumption behavior, and it is risky to continue to provide revolving credit, and will unilaterally stop using the credit card.

The second reason: the risk of illegally cashing out or raising cards. Many cardholders will use credit cards to cash out when the cash flow is insufficient. In fact, this is also of great concern to banks. The issuing bank will either reduce the credit limit of the cardholder's credit card or suspend the cardholder's credit card use according to the cardholder's specific situation.

Reason 3: There are risks. When the bank thinks that the credit card has been swiped on a risky POS machine, or the system prompts that the credit card has been hacked, for security reasons, it will stop paying the credit card.
