Scandit SDK barcode scanner from Mirasense supports fully iPad 2..
But as you already mentioned its not free..
you can also check for PDF417 barcode reader,it is free..
Sorry,this much only i can help you..Let me know if your problem still didn't get solved..
The general problem with scanning barcodes on devices with fixed-focus cameras is that for smaller barcodes, it's very hard to get a decent input image for the library from the camera: The image is either not sharp enough, or too small.
For bigger barcodes, I have had good experiences with ZXing on iPad 2, even though it officially does not support fixed-focus cameras. You should give it a try.
