QR Code

QR code is an abbreviation for quick response code. It is a type of 2-D barcode (also known as matrix barcode). Unlike 1-d barcode, QR codes can encode wide variety of data types, including numeric, alphabets, special characters and binary data as well.
QR code consists of a set of square dots arranged in a square grid pattern with white back ground. The square dots are randomly arranged in order to encode information.

History

QR code was invented in 1994 by a Japanese automotive company named, Denso Wave. Denso Wave is a subsidiary of Toyota Motors

Purpose

Purpose of QR code was to develop such an encoding/ decoding system which allows quick and reliable scanning of fast moving automotive equipment. In workshops, automotive parts are moved quickly from one place to another and are adjusted together. It is difficult to read such type of moving information with simpler barcodes; hence QR Code was developed to cater those needs.
