QR codes are very useful because they allow us to store information in a dot matrix. With an application to read them, you can make your phone understand them, using it to download applications, find locations or grant permissions to access web services, among many other useful functions. And that's the case of QR Code Reader for Android.
The functions included in this app aren't limited to reading or interpreting QR codes which, on the other hand, is its main feature. It also comes along with others, such as its capacity to read barcodes (more usual than the former) and even a built-in flashlight that can help the app to do its job in the event of poor lighting.
The perfect way to read the information contained in a very popular system.
