· What is a QR code and how does it work? Before we jump into the basic works of a QR code, we must first learn the basic concepts of a QR code. A ‘Quick Response Code’ also known as QR code is a two-dimensional type of barcode that Denso Wave develops, a Japanese barcode developer, in 1994. QR codes are scan-able using smartphones devices, which are natively developed to scan/detect QR codes.
