What is SQRC?
The SQRC (Secret-function-equipped QR Code) looks visually identical to a normal QR code but contains an encrypted private data layer alongside the public data. Only authorized SQRC readers from Denso Wave can decrypt the private data.
Why not available?
SQRC is proprietary technology by Denso Wave and not available as an open standard. There are no freely available libraries or specifications for creating this code type.
