I would like to ask what role the QR code will play after the blue invoice is issued by the electronic invoice service platform of the State Water Affairs Bureau. The function is anti-counterfeiting.

The QR code on electronic invoice is a digital anti-counterfeiting technology to ensure the safe application of electronic invoice. By scanning the code, the authenticity can be identified.

Electronic invoice is the product of the information age. Like ordinary invoices, they are distributed to merchants in the form of unified issuance by the tax bureau. The invoice number is distributed to merchants with national unified coding and unified anti-counterfeiting technology. The signature mechanism of the electronic tax bureau is attached to the electronic invoice.
