![]() Adding metadata to barcodes occupies extra barcode capacity. Thereafter, these parts can be transmitted one by one and reassembled together according to barcode markers. This allows dividing a single document into several parts marked with barcode labels indicating file name, creation date, checksum control, and some other additional information. One of the main specificities of PDF417 types is that they support the special format of encoding metadata. PDF417 barcodes can be used to encode streams of bytes or Unicode characters and contain recovery data required for Reed-Solomon error correction. However, it is several times larger than the data density of conventional 1D stacked barcode standards. The PDF417 type provides smaller data density compared with matrix barcode types. PDF417 is a family of 2D variable-length stacked barcode standards that enables laser scanning for documents of high quality (with the exception of Compact PDF417, which supports only photo scanning).
