What is QR Code

QR Code is an image which you can scan through the code scanner of your device, especially mobile. So, it is a machine scannable image which consists of all the information about the text.

QR Code is similar to the bar code printed on the products. Even it is better than bar code on many counts.

The full form of QR Code is ‘Quick Response Code’. As the full form suggests, it gives you the information instantly.

You can see many small squares and some design on it. This is a pattern which has some data. The data in the QR Code may be in the form of alphanumeric, numeric, binary and kanji.

It look that every QR code has the same design. But it is not so. Every code is different from others, as it contains separate information. So, it stores the details in a small square relevant to you.

Note:- Kanji is a form of Chinese characters. These characters are in use in the modern Japanese writing system.

How it Works

QR Code looks complicated. But the working of this code is quite simple. You can get information by just scanning the QR code through your smart phone code scanner. All the payment apps have also incorporated these scanners.

It takes you to the respective image, text or URL. Thus on this image or link, you can verify its authenticity.

A QR may have the information related to a web address, a product code, an image in a binary form, a letter or a list, instructions, maps, a short story, name, address, email, mobile number and account details etc.

Hence the purpose of this a little code is to provide you with the complete information. It also helps to make the cashless payment instantly. Thus it works on the basis of encoding the data stored in the image.
