The MicroPDF417 barcode is a variable-length, alphanumeric 2D barcode with Solomon-Reed Error Correction. MicroPDF417 is referred to as a stacked linear barcode as its 2-dimensional structure consists of vertical stacks of horizontal symbols. MicroPDF417 is based on the PDF417 standard and designed for maximum area efficiency, but without the PDF417's maximum data capacity. It is the perfect candidate to use where PDF417 is applicable but there is a limited amount of space.

Example Barcode

The following example barcode encodes the information "abcdefghijklmnoqrstuvwxqwertyuiop[]asdfghjkl;'z" as an MicroPDF417 barcode:

Details

MicroPDF417 and its unabridged version, PDF417, are unique among 2D symbologies - they are stacked linear barcodes that can be read by linear scanners. Each MicroPDF417 barcode can have between 4 and 44 rows, between 1 and 4 data columns, up to 125 data codewords, and a fixed amount (between 7 and 50) of error correction codewords. This allows encoding of up to 150 bytes, 250 alphanumeric characters, or 366 numeric digits. 1

Barcode Breakdown

The MicroPDF417 symbol is comprised of a couple of components:

Each codeword consists of 4 black bars spaced across the 17 modules that make up the codeword, which is where the name PDF417 originates. Since MicroPDF417 uses base 929 encoding, each codeword represent a number between 0 and 928.
