How to interpret or reproduce the barcode
Every character has nine alternating elements, starting and ending with a bar. Exactly three of the elements are wide. A narrow gap separates characters; an asterisk (*) marks start and stop. The symbols here are the 43 data characters plus the start/stop character.
