If the verification fails, then compare the invoices, mainly in the password area, and errors may occur during verification. You want to make sure it verifies that the information on the scan matches everything on your invoice. If it doesn't work, re-enter the password area, or return to your company to invalidate it and reopen it. This problem also occurred when I was authenticating before. I originally wanted to return it to the supplier, but it was a month later and it was troublesome to consider invalidating it, so I compared it word by word. It can be passed.
