QR And Bar-code Scanner

QR Code Reader is a lightweight and easy to use app that lets you scan any QR code you find. All you have to do is focus your device's camera on the code, and the app will instantly show its content, whether it's a line of text or a URL.
Once you've scanned the QR code, you'll have a series of options available: you can copy the text or URL to your clipboard, share it on any social network you have installed, or search for it directly in Google.

QR Code Reader is an excellent app for two very simple reasons: it takes hardly any space, and it gets the job done effectively. Plus, it lets you scan bar codes and even connect to WiFi networks via QR.
