What is a QR code?
A QR code (Quick Response Code) is a two-dimensional barcode invented in 1994 by Japanese company Denso Wave. Unlike traditional barcodes which store only a few dozen characters, a QR code can hold up to 4,296 alphanumeric characters or 7,089 numeric digits.
Types of QR content
QR codes can encode different types of information: URLs (links to websites), WiFi networks (SSID + password), vCard contacts, email addresses, phone numbers, GPS coordinates, calendar events, or simply plain text.
How does our reader work?
Our reader uses OpenCV, the reference computer vision library used by Google, Meta and NASA. It applies multiple detection strategies in cascade: direct decoding, CLAHE contrast enhancement, multi-scale resampling, and adaptive binarisation to guarantee decoding even of partially damaged QR codes or those photographed in poor conditions.
