## Description

Super CodeReader is a free, powerful QR and barcode scanner extension designed to handle all common formats including QR, Data Matrix, Aztec, UPC, EAN, and more. It offers convenient features like flashlight support for scanning in the dark, zoom functionality to read codes from a distance, and the ability to scan codes from image files or directly using your camera.

Beyond scanning, Super CodeReader enables you to perform relevant actions instantly—open links, connect to WiFi networks, view geolocations, add calendar events, and access contact information easily.
