QR Codes

Until recently I didn’t know what were QR codes, knew that these images were related with something of mobiles and that did something. But as a result of seeing them in adverts lately I have investigate a little more, to create this post to show all information on this topic.


A QR code (quick response barcode) is a system to store information in a matrix barcode or a two-dimensional bar code created by the japanese corporation Denso-Wave in 1994, initially was used to record parts in the area of vehicle construction and the reading of codes were made at high speed.

Today QR codes are used for inventory management in a wide variety of industries. Recently, the inclusion of software that can reading QR codes on mobile phones has allow new consumer-oriented apps, which are manifested in facilities like to stop having to manually enter data on the phones. The addresses and URLs are becoming increasingly common in Japanese magazines and advertisements. The addition of QR codes on business cards is also becoming common, greatly simplifying the task of introducing individual details of a new customer on the agenda of a mobile phone.

QR Code is an open source and the patent rights (owned by Denso Wave) are not exercised.
