looking for best barcode scanner library, besides zxing [closed]
As nithin mention Barcode scanner libraries, one more I would like to add ZBar Barcode Library.
This also contains support for various platform. And it is Open Source.
Scandit has a Barcode Scanner SDK that is available for Android, iOS and Phonegap. There is a free community edition that scans UPC/EAN and QR codes. The SDK also works with fixed-focus cameras (such as on the iPad 2).
(Disclaimer: I'm a developer at Scandit.)
