ZATCA QR Reader

This is a Go based ZATCA E-Invoicing Phase 2 QR Code extraction and decoding tool that can extract the base64 encoded TLV (Tag Length Value) QR code and decode it to display information contained in it.

ZATCA (Zakat, Tax and Customs Authority) is a government organization of Saudi Arabia and has mandated the issuance of electronic invoices with UBL2.1 XML and base64 encoded TLV QR Codes.

This tool can be used by developers to quickly verify their own implementation of Phase 2 QR Code generation or simply extract and view QR Code from any ZATCA E-Invoice.

This tool (with the desktop app) can also be used by non technical people to extract and view contents of QR code from a variety of inputs.
