Stacked Linear Barcodes

The stacked linear barcode symbology features one or two types of 2-D barcodes. These consist of multiple linear barcodes that are layered on top of one another, allowing a greater amount of information to be encoded. However, to fully decode the data, a barcode reader must be able to simultaneously read the code both horizontally and vertically. The stacking of the codes makes barcodes more versatile and allows them to encode a larger amount of information within a smaller space than most other bar codes.
