Usage:
It is widely used in the semi-conductor manufacturing and is particularly
useful where speed, accuracy, and ease of printing are required.
Definition:
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 and it is the
presence or absence of bars in each of the 12 module positions that
make’s it a binary code (hence the prefix “BC”).
The symbology is bi-directional and self-clocking with a start and stop character.
