below.
3.13.3 GS1 DataBar Limited Security Level
The engine offers four levels of decode security for GS1 DataBar Limited bar
codes. There is an inverse relationship between security and engine
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 engine
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.
