DENSO WAVE introduced the QR code in 1994. The team wanted a code that could carry more information than a conventional one-dimensional barcode and still be read quickly. QR stands for “quick response.”
The distinctive square markers let a reader find the code and work out its orientation. That makes it possible to scan a code from different angles.
