1-D Linear Barcodes

A 1-D (one-dimensional) barcode symbology is the typical style with which we are most familiar. All the information in the code is organized horizontally in bar and space widths and read left to right by a scanner. Several versions of 1-D codes store only numerical data while others can encode additional characters. The height of the code varies based on the space available on a product and the ability of a barcode reader to read a small or large sized barcode. The most recognizable 1-D barcodes are UPC codes, which are found on many everyday consumer products, like groceries and household items.
