What's wrong with the dynamic password that China Bank's personal online banking has been prompting?

Error in prompting dynamic password of personal online banking of Bank of China:

Your E-TOKEN may exceed the time and frequency because it has not been used for a long time, or it may be damaged internally or displayed incorrectly due to external forces and other reasons. It is recommended that you bring your valid ID, E-TOKEN and any China bank account related to e-banking to any branch of Bank of China. The teller of China Bank Branch will handle the dynamic password synchronization transaction or replace the damaged dynamic password for you according to the judgment result of your E-TOKEN. In addition, I suggest you open the mobile phone shield authentication, which is safer and more convenient. You can enter the personal mobile banking of BOC and open it online in My-Security Tools-Manage Mobile Shield in the "My-Security and Settings" area, which can replace the dynamic password for transaction authentication.

Tip:

1. China bank counter synchronous dynamic password requires customers to bring their valid identity documents and E-TOKEN media.

2. Customers need to bring their valid identity documents, E-TOKEN media and any China bank account associated with e-banking (credit card verification is required) to the counter of China Bank to change the e-banking account.
