Fastest qr code scanner plugin?

Does anyone know any plugin that scans qr code really fast? I have tried all the 3 native scanners,
I have seen great apps that cans qr code really fast. even with 3.2MP camera,
Barcode Scanner is the worst.
QR scanner and zbar are better but sill it is slow compared to to apps found in the app store,

at the end of the day the speed is mostly governed by the cameras auto-focus speed. The faster it focuses and takes the picture the better.

If you want faster, use an external laser scanner.
