GS1 DataBar is the collective name for a family of 7 compact linear barcodes.
On the Belgian/Luxembourgish market, use is mainly made of the GS1 DataBar Expanded (Stacked), in which additional information can be encoded in addition to the GTIN or GCN.
This information is encoded using Application Identifiers.
This type of barcode is mainly used for two applications:
- for coupons: in this case, a GCN, along with the value of the coupon, is encoded in the barcode
- for weighed items that are scanned at the POS: the GTIN, together with the net weight, is encoded in the barcode
The minimum dimensions for a GS1 DataBar Expanded (Stacked) on a coupon are:
|DataBar Expanded||0,9 cm||6 cm||0,264 mm|
|DataBar Expanded Stacked||1,9 cm||4 cm||0,264 mm|
