"Data Signature Error" of ICBC U Shield. And certificates have expired or are not yet valid.
Is your U shield the kind with a display screen? If yes, please reinstall it. If not, please take it to the bank outlet to try it, so as to determine whether there is a problem with your U shield itself or your installation. If it is a U-shield problem, it means that the U-shield is not sealed and invalid. Conditional outlets can try to fill in again, if not, you can only change a U shield.
