1. Risks of the financing enterprise itself: for example, poor management and irregular management lead to poor financial status. When the financial situation of enterprises is poor, banks will reduce the loan amount or increase the loan interest rate, which will increase the repayment pressure of financing enterprises.

2. The bank card is locked: for example, the bank card is demagnetized, lost, expired or locked by the banking system. In this case, the cardholder needs to carry a valid identity document and bank card consistent with the account opening, and go through the relevant formalities at the bank to unlock it.

3. Frequently enter the wrong password: If the user enters the wrong bank card password for three consecutive times, the bank system will automatically lock the card. Cardholders need to bring the same valid ID card and bank card as when opening an account, queue up at the bank counter for unlocking business, and enter the correct bank card password once to unlock it.

4. Banking system failure: If the banking system fails and the transaction is abnormal, a red warning will be triggered.

5. Money laundering: If a bank suspects that a certain enterprise or individual has money laundering, it will also issue a red warning.
