When you go for payment to the merchant at his store, you see a square image consists of some uneven pattern. It is a QR code. You scan this code and payment is completed from your desired payment option.
But, did you ever think what is this and how the payment can be done only by scanning this square? In this post, I will tell you all about QR Code including its function. So let us start
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.
How to use QR Code
Using the QR Code is very easy. You can get all the details which you require in a few steps. Look at the procedure-
Step 1, Open the QR Code scanner of your device. Alternatively, if you want to pay someone through his QR code, then also you can go through your UPI app.
Step 2, Tap on the QR scanner and align the code in the viewfinder of the scanner.
Step 3, Instantly the scanner will read the QR code and take you at the page where you get the required information.
Moreover, you get a notification on your screen with a link. Tap on the notification to access the link. In this way, you can also make a payment via that link.
Step 4, Alternatively, if you are paying through the QR code it will give you the payee details. Thus now you have to proceed by entering the amount and selecting the payment option into your mobile. Just click on Pay and the payment directly goes to the payee’s account.
About QR Code
Now we talk about QR codes in the context of its’ history and future. Have a look-
1. The History of QR Code
QR code was firstly designed in 1994 for the automotive industry in Japan. Its purpose was to track the vehicles during manufacturing. But now you can see its’ use in much broader areas, especially among mobile users.

Does QR Code Expire
Basically, there are two types of QR Codes, First Dynamic QR Code and the second is Static QR Code. Dynamic code is one which is flexible and editable QR codes. And Static codes are not editable.
Thus, on account of flexible, retrievable and multi purpose use the Dynamic QR code does not expire. Even in the case of multiple times of scanning.
Whereas, the static QR codes expire after some time. So if you go to scan this code, it will not response you or will not take you the required page.
