A particular kind of two-dimensional barcode is known by the trademark Quick Response Code (QR code). The Japanese auto sector was the first to use the QR code. A barcode is an optical label with machine-readable data about the object to which it is attached. To save data effectively, there are four defined encoding modes: numeric, alphanumeric, byte/binary, and kanji.

QR Code

A sort of matrix barcode, or two-dimensional barcode, known as a QR code was developed in 1994 by the Japanese company Denso Wave. QR stands for "rapid response code." A barcode is an optical label that can be read by a computer and contains data about the object to which it is attached. In reality, QR codes frequently contain information for a tracker, location, or identifier that directs users to a website or application. To store information efficiently, QR codes use four specified encoding modes: numeric, alphanumeric, byte/binary, and kanji; extensions may optionally be used.

Due to the quick reading and larger storage capacity of the quick response system compared to normal UPC barcodes, it gained popularity outside of the automobile industry. Applications include document management, general marketing, product tracking, item identification, and time monitoring.
