The Green QR - Safe QR Code Reader app is designed to provide you with a safe and easy way to scan and view QR codes. It is developed for Android devices and can be used with your default camera. The app has been designed in a way that it does not require any special permissions to function properly. It is safe to use and it has a clean and simple user interface.

The way it works is that it first captures the image of the QR code and then uses the default camera of your device to scan the code. After scanning, the app will display the results on the screen.
