How to create QR code

Although most QR codes are provided by a company. So that you can use its services easily. And can use the security and other features provided by it. You can make your payment etc. But if any normal person also wants to create his own QR code, he can create it using online tools.

But first of all it depends on which accountant you want to make QR code. That is if you have any URL or any such website page. For which you want to create QR code, then you can use Google Chrome. But it is only available to computer users. Mobile users cannot create QR codes from their Google Chrome.

QR code of any web page can be easily created, the biggest example of this is Google Chrome browser. For this, you search anything in your computer’s Google Chrome browser, be it in Google or on any other website and click on Generate QR Code. The QR code of that page will be generated, and if you want to send the direct link to any person, you can also send it.

How to scan QR code

The QR code is scanned with the mobile’s camera, but not with the camera application. Rather it depends on which accountant’s QR code you want to scan.

For example, if you want to pay someone. And it has QR code of Googlepay or Phonepay or Paytm etc., then you can scan it with any payment gateway like Googlepay phonepay paytm etc. And you can make payment for which you have to go inside that application. And you have to go to the option of scan and your mobile camera will open. Now you have to scan that code and complete the further process.

Just go into your WhatsApp and click on 3dot to scan the link device by clicking on it. Apart from this you do not have to do anything. And your WhatsApp will start working on your computer as well.

And if you want to scan any QR code that is based on a simple URL. And there is no verification or payment URL in it, then you have to scan it with a normal QR code scanner app.

Because some specific QR codes can only be scanned with some specific applications. And normal QR code can be scanned with normal QR code scanner only.

That’s why you should only scan the QR code that you can trust, otherwise you can be fraud. Because many qr-codes may have been created by hackers in which a malicious link has been included.

What to do if the QR code is not scanning

If you are scanning someone else’s code and it is not working. So it could mean that you are scanning a verification QR code.

For example, to make a payment or to run WhatsApp web, etc., in such a situation, you will have to scan that specific QR code through a specific application only. And normal QR code scanner applications will not work.

But if still the QR code is not working. So it could mean that your phone’s internet connection is down. Because internet connection is required to access any URL.

It has been damaged, or it may be that the camera of your phone is not clear. ¬†Because if your phone’s camera will not be able to capture its barcode clearly, then the scanning will fail.
