Such stacked or multi-row barcodes store information in two dimensions. Several stacked linear
barcodes are used to encode the information.
3.2.1.3 2D Barcodes (Matrix Codes)
Figure 3: 2D Barcode Sample
Two-dimensional barcodes like MaxiCode, Data Matrix or QR-Code encode information in two
dimensions. Compared to stacked symbologies the information is not stored by using different bar
(space) widths. Instead the position of black (or white) dots is relevant.
3.2.1.4 Composite Codes

Figure 4: Composite Barcode Sample
Composite codes like GS1 DataBar Composite Symbology are combining linear with 2D (stacked)
symbologies. The advantage of such codes is that the linear code component encodes the most
important information. The 2D component is used for additional data. This separation ensures better
migration (e.g. with respect to scanning hardware) between linear and 2D technology.
