MicroPDF417
MicroPDF417 is two-dimensional (2D) stacked barcode symbology invented in 1996, by Frederick Schuessler, Kevin Hunter, Sundeep Kumar and Cary Chu from Symbol Technologies company. MicroPDF417 consists from specially encoded Row Address Patterns (RAP) columns and aligned to them Data columns encoded in "417" sequence which was invented in 1990. In 2006, the standard was registered as ISO/IEC 24728:2006.
MicroPDF417 barcode can be read with both barcode reader technologies like laser scanners and camera-based readers. As most of 2D barcodes, MicroPDF417 standard contains Reed–Solomon error correction with ability to read corrupted images and high data density. However, data which can be encoded in MicroPDF417 is only 150 bytes or 250 alphanumeric characters in the biggest 4-columns version. Also, because of design, MicroPDF417 barcode can be used only for high-quality documents and images.
MicroPDF417 in common modes can encode text, numeric, binary data and Unicode text with Extended Channel Interpretation. Additionally, MicroPDF417 contains special modes which can encode text and numeric data in special formats, which can be used, as an example, in GS1 Composite bar code symbology.
MicroPDF417 barcode was patented in 1996, by Frederick Schuessler, Kevin Hunter, Sundeep Kumar and Cary Chu from Symbol Technologies company. MicroPDF417 is an extension of PDF417 barcode and uses the same principles of data encoding. Before 2006, the standard can be obtained only from AIM store as ITS MicroPDF417 standard. At that time, it is used as part of ITS - EAN.UCC Composite Symbology. In 2006, MicroPDF417 standard was brought out as ISO/IEC 24728:2006 and can be used independently or as part of GS1 Composite barcode symbology.
MicroPDF417 is mostly used to add extended data to linear barcodes. MicroPDF417 has high encoding density and in this way, it can add more additional data in lower space. At this time, it is used in inventory management and goods labeling as part of EAN.UCC Composite Symbology and GS1 Composite barcode symbology. Most of barcode printers and barcode scanners have MicroPDF417 support.
MicroPDF417 barcode symbol consists from at least two Row Address Patterns (RAP) columns which are used to detect row numbers and aligned to them Data Columns. MicroPDF417 barcode symbol has four versions with 1, 2, 3 and 4 data columns. The barcode can be split to the following elements:
Every MicroPDF417 barcode data column versions can be split into predefined numbers of rows which are different for every version. Row height should be from 2 to 5 times higher than minimal module (bar or space) width.
MicroPDF417 Row Address Patterns (RAP) are stacked into columns. Each RAP is used as indicator of row number, but RAP is not the same as row number. Every MicroPDF417 RAP consists from 10 modules, which are split to 3 black bars and 3 white spaces. Bars and spaces size can vary from 1 to 5. Each RAP row starts from black bar and ends with white space. Right RAP has additional completing black bar.
