New trend of QR code technology

A QR code is a matrix code or two-dimensional bar code. It was invented by Japanese corporation Denso-Wave in 1994 with the aim of allowing its contents to be decoded at high speed. It was first designed for inventory management in a wide variety of industries and most common in Japan. However, today it is developed in almost all areas in many countries around the world.

1. What is QR code ?

A QR code abbreviated from Quick Response code is a specific matrix barcode that is readable by dedicated QR bar code readers or camera smartphones. The code consists of black modules arranged in a square pattern on a white background. The combination of these modules encodes any online data, including: links to web pages, images, product information and advertising.

The difference between QR codes and traditional bar codes is the amount of data they store or share. A traditional bar code with one-dimensional line can only store 20 digits, whereas a two-dimensional QR bar code can store up to thousands of alphanumeric characters. QR codes contain lots of information and are easy-to-use that will be helpful for users in all areas.
