What is QR Code || How to Create and Scan
Although many schemes of the Internet have come and gone, but one thing that has been going on for years is the QR Code or Quick Response Code. So today in this article we will know what is this QR code and how does it work. Today we will know about it in full detail. So what’s the delay, let’s get started.
The full form of QR Code is “Quick Response Code”. They are similar in appearance to the square barcode that was first developed in Japan. It looks exactly like the traditional UPC barcode which are like horizontal lines.
But they are more attractive and more information can be stored in it. Also it can be captured very easily. If another definition is given, these are machine readable labels. Which the computer can understand much easier than understanding any text.
QR codes are used everywhere such as to track or identify a product. As such, it is an improved version of the unique barcode. Which technology hasn’t imprisoned itself that it can only be used to track a product in a warehouse?
Rather its use has increased a lot like nowadays we can see it in advertisements, billboards and business windows also. Even some websites are using it.
Why is QR Code so important
You must have got a little idea what a QR Code is. If you’ve never heard of QR codes before, you might be pushing your head too hard.
Those who are already connected to the internet would already know about what this square shaped barcode is. This may sound a bit strange in appearance, but the small business owner and entrepreneur should be aware of it.

Talking about a consumer like us, with the help of QR code, we can easily do some work using our smartphone. Unlike NFC (Near Field Communication), it does not have any fancy electronics or any special technology is being used in it.
It is just a grid of white and black which is printed on some paper and can be easily captured with the phone’s camera. The QR code is first captured with the help of a scanner app, then that app converts that code into some valuable information. which we can understand.
For example, if you saw a QR code in which ad board and scanned it, it took you to a website, that means the URL of which website was embedded in that QR code. QR code works similarly.
What is the difference between QR Code and 1D UPC Barcode
By the way, there is a lot of difference in their look as well. One looks like blank vertical lines and the other looks like a square box. If we talk about scanning, then we can scan QR code from any direction (vertical and horizontal) but we can scan barcode from only one direction.
Up to 30 numbers can be stored in 1D barcode (UPC) but in QR code we can store up to 7089 numbers.
Due to this huge storage capacity, videos and large files can be stored in it very easily. Which is later used in social networking sites like Facebook and Twitter.
