How to Scan QR code using webcam and php or javascript

Question

I am trying to implement QR code. i've successfully implement it using phpqrcode. However I don't know about how to decode the QR code using webcam and php or javascript. I've tried to search it on google, but can't find any solution for this. Anyone could help me? Thank you so much

Solution

you could use this jquery webcam plugin and then send the image to php-zbarcode. It uses zbar which can read qrcodes. Note that the plugin requires flash.

There is also jsqrcode which you could use to scan and interpret the QR Code, however this requires HTML5 for displaying the webcam output, and flash for capturing.

Here is a previous question pertaining to javascript-only solutions
