Widely used in semiconductor manufacturing. Particularly useful where
speed, accuracy, and ease of printing are required.
BC412 (Binary Code 412), a proprietary IBM symbology since 1988, is an
alphanumeric symbol with a set of 35 characters, each encoded by a set of
4 bars in 12 module positions. All bars have a single width; it is the presence
(1) or absence (0) of bars in each of the twelve module positions that make
BC412 binary.
This symbology is also bi-directional and self-clocking, with a start character
and a stop character.
