    Decode Drivers Licence Barcode

    It works for me. Make sure that you covert the hex to a byte array. Also skip the first 6 bytes, then decode a block of exactly 128 bytes.

    Zxing is designed for mobile devices where you have stream of images, so it doesn't work well for decoding a single scan, and apart from that it's bad at pdf417. You'll find many pdf417 libraries on google - just try a few.

    Decode Drivers Licence Barcode

    Decryption details are here: http://pastebin.com/gb049dfx Still tricky to get the implementation right. Once the data is decrypted, the decoding is not that complicated (may post details later if I get the time to write it all up). Decoding the photo is complicated - no idea how zeely does it...
