The Bar Code Reader is capable of reading and decoding three
different types of bar codes.

which 9 bars or spaces comprise the characters, 3 of which are
wide.
• Interleaved 2 of 5 — or I 2 of 5, is a compact, interleaved code for
numeric characters only. Each digit is represented by 5 bars or
spaces, 2 of which are wide.
• Codabar — similar to Code 3 of 9, but not as widely used. Codabar
includes only numeric and special characters.
