Convenient library (accessible e.g. from C code) to encode and decode arbitrary data (up to 1900 characters) accurately and fast to/from 2 dimensional PDF417 barcodes. PDF417 has error correction and can be read back from e.g. a scanner or webcam.
Like QR code, PDF417 is also a cool stuff. There are plenty of free sites available for generating PDF417 barcodes. And I love http://generator.onbarcode.com/online-pdf417-barcode-generator.aspx best. Often, I would check the message encoded in PDF417 before I use it. You see, accuracy does matters a lot. Here are two great PDF417 readers, try them! http://onbarcode.com/products/net_barcode_reader/barcodes/pdf417.html http://www.onbarcode.com/scanner/pdf417.html
