What is QR code??

QR code means a quick response code. This code is sized in rectangle shape. In this, we can store any data and send it to another person in the form of code. The QR code is exactly the same as the barcode. But it sees something attractive. 

The best part of this code is that we can store unlimited data and we can't store unlimited data in a barcode.



Who developed the QR code ??

The QR code was invented in Japan in 1994. A company named subsidiary developed the QR code. The code was developed to track the subsidiary company's products. But now along with tracking, data is also being used to store it. This mine invention has been developed in Japan and the whole world is using it for their business. Now, this code has become a part of the business.



How to use 

We can use this code in many ways. for example
  • You can store your business contact details.
  • Can store the URL of any of your websites in the form of code.
  • You Can show it to another person by storing a message.
  • Paytm and Phonepe can also use QR code to pay the hotel bill 
  • You can easily access wifi by storing the wifi username and password.
  • You can see your details by scanning the code on the Aadhar card.
  • We can increase followers by storing the URL of Facebook as a code on our website.
And there is a lot of use, you can do many other things using your brain.



Why QR code is better than Barcode?

1. We can call the QR code an upgrade version of the barcode. Because we can store only characters (123456789) in the barcode. That too to a limited extent. But in this, we can store unlimited data. In this, we can store alphabets, website URLs, messages, Facebook URLs, and so on. 

2. The bar code contains a vertical line. If a scratch occurs, it is impossible to read the data. But the same scratch comes in the QR code, so the data can be read comfortably.

3. To read the data in barcode the scanner needs to keep straight. But in QR code we can scan easily from any direction.

These are the 3 three points that QR code is better than Barcade.



Types of code.

QR code is 2 Type. A static code and another Dynamic code.

1. Static Code

We can see all these given below by generating the static code
  •  Which device is scanned, which OS is it, we can see it all with the help of static code

2. Dynamic Code

We can see all these given below by generating the Dynamic code
  • We can see the code scanner name, Gmail id.
  • How many times is the code scanner?
  • Conversation Rate etc. This is all we can see.



How can we generate??

There are many websites on the Internet, using which you can generate this code.

steps to generate -

1. First of all, you have to open the website by typing Qrcodemonkey on Google. You can also use another website if you want. But on this website, you have multiple options.

2. Once the website is open, you'll get a lot of options. Select you to want to create and provide information.

3. After giving the information click on Create Code and generate the code.

This is the way you can easily generate this code on any website.



What kind of data can we store ??

In this, we can store a lot of data. Such as website URLs, message, email, phone number, Vcard, Location, Facebook URL, Twitter, Instagram, WhatsApp login, bitcoin, Events, wifi passwords, so much data we can store in this code. This is the best part of this code that we don't get to see in the barcode.



Application -

You can download all of the applications listed below from the play store to your phone and read this code data. All applications will allow you to download and use anyone's application.




How to Scan.

In 1994, the QR code scanner mission was required to read the code. But now the technology is so advanced that no mission is needed to read this code. We can also scan this code with the help of our phone's camera.

steps to scan -

1. The first thing to do is to download the QR reader application from the play store.

2. After downloading, the one who wants to scan the QR code is to scan the code.

3. All the data in that code will show on your phone as soon as it is scanned. If there is any URL, it will open directly on Google.



The disadvantage of QR codes.

There are disadvantages to any product with an advantage. It is the same in this. There is a disadvantage even after having so much advantage. If a hacker creates a malicious link in a QR code and gives it to us to scan. And if we scan the link without thinking anything, our data can be leaked or hacked. Well, this condition is rare.

But it is good for us to be careful. Whenever any person asks you to scan the QR code, then know the complete information on how that person is. If that person is trusted then only scan the code.

Many people visit the unknown website and scan the code lying on it. This can also hack your phone. If it is a trusted website then only scan. Don't scan the code on an unknown website.
