I need a barcode scanner to include in my phone call project

I am looking for an existing project / API for a barcode scanner. I want to include a barcode scanner in my phone call project so I have to work using JavaScript .... Any suggestions ??? It should be able to scan BarCode, not QR code !!!

Just found: http://code.google.com/p/zxing/ (But it only scans QR codes ?!)

Thank!
