Insert text and get correct PDF417-code immediately. Share or copy high resolution image in PNG format or PDF file. Paste into any document or message. 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. The new compact PDF417, or Compact Portable Data File 417, has the same features as PDF417 standard. However, Compact PDF417 may be used where space considerations are a primary concern and symbol damage is unlikely. In an environment where label damage is unlikely (e.g. an office), the right row indicators, that PDF417 Symbols feature, may be omitted and the stop pattern may be reduced to one module width bar. This procedure reduces the non-data overhead from 4 codewords per row to 2 codewords per row, with some trade-off in decode performance and robustness, or the ability to withstand noise, damage, degradation, dust etc. This overhead reduction version is called Compact PDF417, which is fully decoder compatible with standard PDF417. 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.
