If you’re an Android user, you’ve probably encountered QR codes before. These codes are everywhere, and when you encounter one, you can either take a picture of it with your phone’s built-in camera or use a QR code reader to get more information.

What is a QR code?

It’s a kind of barcode that can be used to store information. When you scan a QR code, it will take you to a website or other app where you can view the information it contains. 

The QR Code Reader: Scanner App can be useful if you’re a business that wants to promote its products and wants customers to scan its code and buy its products. It can also be helpful if you’re a customer who wants to shop at a particular store or restaurant and wants to make your payment through this method.
