Several common reasons for entering a dark room:
1. Withdrawing a temporary line, withdrawing cash with a credit card, making the lowest repayment, exceeding the limit, and having overdue records in other banks.
2. The mobile phone number is used by others.
3. The information filled in when handling a savings card and a credit card is different.
4. Modify materials and apply for cards frequently. Changes to the retained credit card information will be marked as "anti-fraud black words" by ABC.
5. Return your credit card to the risk control system of ABC with a savings card in someone else's name. Using someone else's savings card for a long time still has repayment risk.
6. Use the reserve fund.
7. One or two channels such as WeChat, Alipay, China Unionpay Quick Pass, JD.COM and Taobao often use credit cards. Payment using only one or two of these platforms will be judged as single consumption.
