    QR-coded Tax Invoice

    A tax invoice that carries a machine-readable QR code encoding key invoice fields (seller VAT, totals, timestamp, hash) so any buyer can verify the invoice with the tax authority.

    More Details

    QR formats are jurisdiction-specific: ZATCA uses TLV (tag-length-value) Base64 encoding; India's NIC returns a signed JWT; Nigeria's FIRS embeds the verification URL; Kenya's eTIMS prints the Control Unit Invoice Number plus a QR. In every case the QR is the buyer-side verification surface.
