The code wrtz 120 of China Merchants Bank indicates that your bank card is in an abnormal state, which is generally caused by frequent small transfer transactions. The way to eliminate the abnormal state of savings bank card depends on the situation. 1, the information has not been updated: the solution is that users bring relevant information to the savings bank to update their identity information; 2. Bank card loss reporting: If it is a temporary loss reporting, you can call the customer service staff of the savings bank to cancel the loss reporting, or go directly to the savings bank outlet to cancel the loss reporting; 3.

Bank card risk control actually means that banks control the risk of bank cards. Bank cards generally use a risk control management system to protect user accounts and avoid unexpected financial losses. This is a risk monitoring method. If the bank risk control system automatically captures the abnormal situation of the bank card, the account will be frozen and the bank account will be controlled by the wind. This is also the case. 2. For example, when the amount of bank card funds is too large, the bank will conduct risk monitoring. If the tracking feedback results show that there is no violation of laws and regulations, the risk control will be released. 3. In case the bank card is controlled by the wind, first communicate with the bank and ask the staff why the bank card is controlled by the wind. If it is an account controlled by the bank because of illegal attacks or other illegal operations by non-users, the bank will unlock the bank card user after verifying the relevant situation, and the user can modify the account password. Users can also try to use bank cards and credit cards frequently in large supermarkets to prove that they are normal users. At the same time, they should pay attention to the credit card quota, not too low or too high, and increase the number of credit cards accordingly. Of course, if you only do normal business operations such as transfer and remittance, you don't need to worry too much about the risk control of bank cards.
