ScanQR

Scans QR codes using your webcam.

What is ScanQR?

"ScanQR" is a handy Chrome extension that allows users to scan QR codes using their webcam. Compatible with various devices, it captures and deciphers QR codes, converting them to easily readable texts. It currently works best with Chromebook Pixel, Samsung ARM Chromebook, Acer C7 Chromebook, and certain versions of MacBook Pro. The functionality with other devices may depend on the size of the QR code and focusing capabilities of the webcam. The developer intents to improve compatibility as Chrome allows manipulation of camera focus settings.

Extension summary

Analyze keywords

Scans QR codes and displays their contents on a Chromebook or other computer with a suitable webcam. What's a "suitable" webcam? It's one that can focus the QR code within the red square in the app sharply enough that the app can decode it. My test results:

Chromebook Pixel: yes
Samsung ARM Chromebook: yes
Acer C7 Chromebook: yes
CR48: yes
2009 MacBook Pro: yes, except for very small, dense QR codes
2011 iMac: no, unless the QR code is ridiculously large (over one foot across)

If Chrome implements an API to let developers adjust camera-focus settings, I'll be able to improve the app to work with more cameras.
