BarcodeLimitedMarginCheck
Description
Limited margin check.
Values of this enumeration:
- Level_1 - No clear margin required. This complies with the original GS1 standard, yet can result in erroneous decoding of a DataBar Limited barcode when scanning some UPC symbols that start with digits 9 and 7.
- Level_2 - Automatic risk detection. This level of margin check can result in erroneous decoding of DataBar Limited barcodes when scanning some UPC symbols. If a mis-decode is detected, the scanner operates in Level 3 or Level 1.
- Level_3 - Margin check level reflects the newly proposed GS1 standard that requires a five times trailing clear margin.
- Level_4 - Margin check level extends beyond the standard required by GS1. This level of security requires a five times leading and trailing clear margin.
