What is a Barcode?
A barcode is a machine-readable representation of data, encoded as a series of parallel bars and spaces of varying widths. Barcodes are scanned optically at checkout counters, in warehouses, and in logistics to instantly identify products and track inventory.
Different symbologies serve different purposes: CODE128 is a versatile high-density format for general alphanumeric data, while EAN-13, EAN-8, and UPC-A are fixed-length numeric standards used worldwide for retail product identification. ITF-14 is used for carton and case labels, and CODE39 is a classic alphanumeric format popular in industrial and government applications.
