Legal analysis: 1. If it is a savings card, it may be that the cardholder has been monitored by the bank and has traces of anti-money laundering, or the card is in danger of being stolen. In this case, the cardholder needs to bring his card and ID card to the bank counter for cancellation.

2. If it is a credit card, it is generally because the user maliciously overdraws or is overdue for a long time. Users can call the customer service phone of the credit card center of the issuing bank to inquire about the specific reasons for being marked with high risk and how to solve it.
