QR Code Technology

INTRODUCTION

Quick Response (QR) code is a 2D code which works as a barcode with some additional features and information. Unlike barcode which contains the combination of black and white straight and parallel lines and 12 digits number at the bottom, QR code is a maze like visual pattern. The pattern looks like a collection of black and white small strings and paper pieces enclosed in a square area. It does not show any number with it.

Knowingly unknowingly, we use QR code very frequently. Specially while making payments at the retail store or food joint through application like paytm in our smartphones. These types of apps have the QR code reader or scanner inbuilt in it and convert the QR pattern to a comprehensive form.

QR Code

However, the usage of this code is not limited only to making payments, but its usage extends to open any app or website. It helps is verification and storing personal information, promoting content etc.

It was developed in Japan by a subsidiary unit of Toyota Motors in 1994. This unit named Denso Wave was responsible for the assembly of motor parts and used QR code to monitor and record the manufacturing and assembling of these parts. The credit of inventing the QR Code goes to an engineer in Denso Wave, Hara Masahiro.
