Hello: the solution to prompt "signature verification failed" when paying. If it is payment, the page prompts "202 100 1, signature verification failed" or "signature parameter is missing". The digital certificate you installed may have expired. Please delete Tenpay digital certificate and reinstall it on this machine. Please click here to view /info/37882. Tips: If the problem still exists after reinstalling the certificate, I suggest you empty IE cache and try the payment operation again. Please click here to see how to clear IE cache/info/43282.html.
