What does it mean that ICBC account authentication is abnormal?

Abnormal ICBC account authentication means abnormal bank card consumption. According to relevant public information, if a bank card is stolen or swiped in a large amount in an area where the cardholder has never swiped the card, it will be monitored by the banking system, and the bank will judge that the card is at risk of being swiped, and then display abnormal transactions. The basic information reserved by the bank mainly includes name, address and identity information. If the information is incomplete, does not match the real identity or the certificate is expired, then the transaction will be restricted by the bank.
