Provides increased encoding capacity and supports metainformation In turn, the Micro PDF417 type can encode up to 266 alphanumeric characters or 366 numerical digits or 150 bytes with the maximal configuration of 44 rows and 4 columns.Ĭan be used to work with documents of any quality and supports laser scanningĪllows minimizing the barcode area and can be used as an add-on for GS1 composite symbologies or applied to high-quality documents Basic PDF417 can be used to encode at most 1,850 alphanumeric characters or 2,710 numerical digits or 1,108 bytes with the maximal configuration including 90 rows and 30 columns. The PDF417 layout configuration is composed of multiple rows and columns. 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).
