I am looking for some best barcode libraries on all platforms. I know zxing but wondering more libraries besides it. Any help is appreciated~
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.)
For iPhone and Android both you can look into the below link:
This same works for both iPhone and Android.

Hope this helps you.
Best PDF417 decoding library we've worked with by far was Manatee Works's library, already ported to most available mobile development platforms and cross-platform frameworks.
