Signature failure may be caused by the following reasons:

First, the certificate is expired or damaged, and I bring my ID card and bank card to the bank outlet to renew the certificate.

Secondly, the wrong password input leads to failure. There are two kinds of data signatures, one is static and the other is dynamic. When transferring payment, the system will prompt you to enter the corresponding number or letter on the password card, which needs careful proofreading to avoid mistakes and failures.

thirdly, the bank card can only pay by opening the online payment function at the bank counter, otherwise it will also lead to failure.

fourthly, the certificate was not installed correctly due to the problem of rural network, so it is suggested to delete the original certificate and install it again.

fifth, the business of changing registration and canceling registration: the information originally registered in the industrial and commercial sub-bureau is wrong, which leads to the failure to verify the information of relevant personnel.
