Scan any PDF417-code, get decoded result as a text, and reworked PDF417-code. No internet connection needed. Save generated and scanned codes in a local database and restore them at any moment. PDF417 is used in many applications such as transport, identification cards, and inventory management by both commercial and government organizations. The app provides a PDF417 barcode image for those electronic and paper documents. Available on iPhone and iPad.  Barcode PDF417 is public domain format. Anyone can implement systems using this format without any license. PDF417 is a stacked barcode that can be read with a simple linear scan being swept over the symbol. Other 2D codes, such as DataMatrix and QR, are decoded with image sensors instead of uncoordinated linear scans. Those codes still need recognition and alignment patterns, but they do not need to be as prominent.
