Step 1: It prompts you whether it is the face value of the invoice. Just check whether the invoice number is wrong, that is, whether the number on the invoice is consistent with the invoice number issued by the other company. If not, please return it and reopen it.
Step 2: "Please confirm whether the printed contents of the invoice face are consistent with the displayed ciphertext data". If the invoice number is excluded, it may be that the ciphertext area is not very clear and the scanning is wrong. Then you should carefully check every number and symbol in the encrypted area of the invoice scanned into the computer (the box in the upper right corner). There must be a discrepancy between the invoice and the information scanned into the computer. Just change it in the computer. If you don't know where to look at the invoice scanned into the computer, you can call Shunchi (the company that provides invoice authentication system) for consultation, and they will give careful guidance.
