MinQRReader is a free QR code reader developed by Dr.T for Android devices. As the name suggests, this is a tiny app that can read QR codes and one-dimensional barcodes. The app has only the minimum required permissions, which makes it lightweight and easy to use.

One of the best features of MinQRReader is that it can call associated applications when a code is read. This means that if the code contains a link to a website, the app will automatically launch the default browser and open the link. Additionally, the app can also be called from other applications, making it a versatile tool for anyone who needs to scan QR codes on a regular basis.
