GS1 DataBar Limited Security Level
The decoder offers four levels of decode security for GS1 DataBar Limited
bar codes. There is an inverse
relationship between security and decoder aggressiveness. Increasing the
level of security may result in
reduced aggressiveness in scanning, so only choose the level of security
necessary.
•
Level 1
– No clear margin required. This complies with the original GS1
standard, yet might result in erroneous
decoding of the DataBar Limited
bar code when scanning some UPC symbols that start with
the digits “9”
and “7”
.
•
Level 2
– Automatic risk detection. This level of security may result in
erroneous decoding of DataBar Limited bar codes when scanning some
UPC symbols. If a misdecode is detected, the decoder operates in Level
3 or Level 1.
•
Level 3
– Security level reflects newly proposed GS1 standard that
requires a 5X trailing clear margin.
•
Level 4
– Security level extends beyond the standard required by GS1.
This level of security requires a 5X leading and trailing clear margin.
