Field notes
The homepage describes a fixed QR2HD design whose ordinary QR payload remains recognizable while HD Barcode dots carry additional product data. Its demonstration separates a public message from a protected message: the reader scans an authorization symbol before revealing the latter. The proposed consumer flow relies on a normal phone camera and browser, with no dedicated app or scanner. The page also identifies a 0.6-inch printed area shared by the QR, HD data, and physical authentication features.
