W1z / W1Z: MicroPDF417

Valid Characters: All ASCII characters, depending on the selected options.

Variable Length: This is a 2 dimensional barcode capable of holding large amounts of data in a small area. It provides a high level of redundancy and error checking.

Specified Length: With a string four-digit length specifier, values 0x00 through 0xFF to be included within the data strings without conflicting with the DPL format record terminators.
