What is a QR code? A to Z details of QR code. Almost everyone knows what a QR code is. The complete form is the Quick Response Code. QR codes are called QR codes because any encrypted information can be easily stored and accessed quickly. QR Code is a type of two-dimensional bar code. QR codes are mainly used to store product prices, various promotional offers, or much more information in a small space.

There are two types of QR codes, one of which is dynamic: the QR code that can be changed even after it is created is called dynamic QR code and the one that cannot be changed after the QR code is created is called static QR code.

Why use QR code?

Suppose you have a company whose job is to make vessels. Suppose your company makes vessels of different prices and after a few days the price of those vessels goes up. Suppose you have printed its price on each vessel. When the price of the vessel will increase, but the previous price will be written on the vessel. Suppose your company has changed the price of a vessel from Rs 40 to Rs 50 and the price of Rs 40 on all the previous vessels has automatically changed to Rs 50. Wondering if this is possible? Yes ... you can do this very easily with QR code.

Now suppose you have a local business. So you have given customers a very tempting offer. If anyone wants to accept the offer, he/she has to write BCoffer and send an SMS to 61***77. Now if any of your customers want to take this offer, they have to go to the message option and type SMS. Suppose your customer sends you an SMS but you don't have to type anything in the message option. Wondering if this is possible? Yes ... you can do this very easily with QR code.

Suppose one day you have an accident on the road and you fall unconscious. To identify you, a pedestrian took the phone out of your pants pocket and saw that everything, including its SIM, had been smashed. Then he took out a wallet from the back pocket of his pants and saw that there was a picture of you and a small QR code next to it. Someone scanned it with his mobile phone and saw all the information including your parents' phone number and address. Then he took you to the destination.

Also, your customer will call you but you don't have to type number, someone will save your phone number in contact list but the name address phone number will be typed automatically, link to the different web site to visit without typing in browser QR codes are used to get out.

How to create QR code for free?

There are many software, apps, or websites for creating QR codes. But the best QR code creation website for me is The_QR_Code_Generator. From this web site, you can create free QR codes. In addition to static QR codes, dynamic QR codes are also available on this website. You can also track who has seen the information by scanning your dynamic QR code from this website. Oh, I didn't tell you the details about dynamic and static QR codes. So let's talk a little bit about these.

What is the dynamic QR code? | How QR code works

As I said before, the QR code that can be changed even after it is created is called a dynamic QR code. Suppose the price of your company's vessel is 40 rupees, write this word and make a QR code and seal it on the vessel. Suppose the vessel has been sent to the market for sale, then you increased the price of the vessel. And someone scanned the previous QR code of that vessel and saw that the price of the vessel has gone up to Rs. Notice here but the QR code is the same, but the scan shows the current price without showing the previous price. This is an example of a dynamic QR code. To view dynamic QR code information, the mobile must have an internet connection.


How does dynamic QR code work?

When you scan a dynamic QR code with your mobile, it shows you a link to a website, which when clicked shows the details in the QR code. Therefore, all the information stored inside the dynamic QR code is stored on a webserver. When someone changes the information on that web server, someone scans the QR code and sees the changed information on that same web server. Since all the information in the dynamic QR code is stored via a link to the webserver, the dynamic QR code looks much less dense to look at.

What is a static QR code? | How QR code works

As I said earlier, a static QR code is a piece of information that cannot be changed once it has been generated. Static QR code information is stored within the pattern of the QR code so no internet connection is required to view the static QR code information. However, the higher the amount of data, the denser the static QR code will be and the more difficult it will be to scan

QR Code Scanner Download

There are many apps in the Google play store that allow you to scan QR codes. Personally, I use the QR & Barcode Scanner app. You can also download it if you want. It allows you to scan both QR code and Bar code.

I hope I have been able to give you a clear idea about the QR code through this article. If you have any problem while creating QR code or if you don't understand any part of this article, you must comment.
