is a 2D barcode symbology. It has a unique structure and large data capacity.
PDF417 empowers you to encode over 1000 alpha-numeric characters within one symbol, both ASCII and extended ASCII characters.
Therefore, PDF417 barcode is a good solution for encoding large quantities of data in one symbol.
PDF417 uses Reed-Solomon-algorithm for error correction. The higher security level is, the larger size of pdf417, the less decipher error chance. If not specified, software will use default level 0. Level 0 means automatic security selection.
