must be successfully scanned in both directions (forward and reverse) before reporting a good decode.

Intercharacter Gap

The Code 39 and Codabar symbologies have an intercharacter gap that is customarily quite small. Due to various
bar code printing technologies, this gap may grow larger than the maximum size allowed, causing the scanner to
be unable to decode the symbol. If this problem is encountered, scan Large Intercharacter Gaps to tolerate
out-of-specification bar codes.
