When handling the payment certificate of Hangzhou Bank, it shows that the signature is wrong.
If you have two U shields, you may have inserted the wrong U shield. If there is only one U-shield, the owner of the bank card can take his valid ID +U-shield+bank card to the nearby ICBC outlet to find the account manager of the electronic bank to restore the U-shield, and then download the digital certificate to the U-shield again.
