Packaging South Asia gets QR’ed

• Decrease Increase

We all come across or have seen a 2-D barcode of small black and white squares looking like a crossword puzzle without the numbers. It’s placed in a corner of a printed ad, or on the object itself. This barcode is called a ‘QR’ code – it’s a matrix code developed by a Japanese company named Denso-wave in 1994 and is widely used in Japan, Europe and America. QR stands for Quick-Response machine readable code that was designed to have its content electronically decoded at high speed.

It works on the principle of dark and light square data modules. It has position detection patterns on three of its four corners and features direct encoding of the Japanese Kana-Kanji character set. The use of the QR code is free of any license.
