PDF 417 is a multi-row, continuous, variable length symbol which has high data capacity. Each
symbol has between 3 and 90 rows, with each row containing a start pattern, a left row indicator, 1 to
30 data characters, a right row indicator and a stop pattern. The number and length of the rows are
selectable, which allows the aspect ratio to be adjusted to particular labeling applications. There are
no separator bars between rows.
Each character has four bars and four spaces within 17 modules, and is assigned a value between 0
and 928. For this symbol, it is common to refer to these character values as “code words.”
