Barcode Scanner is a very useful application thanks to which you can use your device's camera as a barcode reader. Its most useful function, without a doubt, is its ability to create QR codes, which allows you to share the information of any application or contact on your list by simply selecting its name. In the same way, all you have to do is place your camera's phone in front of a barcode so it automatically recognizes it and interprets it with no problem. You will need, however, very good lighting for this. Barcode Scanner is a very useful application for any Android user, as it is becoming increasingly more common to find interesting information stored in QR codes.
