A barcode is a machine-readable symbol that encodes data, such as product identifiers, batch numbers or dates. The symbol differs from the identifier it carries: a GTIN identifies a trade item, while the barcode makes encoded data readable to suitable scanning equipment.[1]
When scanning fails, check the data, print quality and symbol type. A correct number does not help if the label is unreadable. Conversely, a perfectly scannable label can still refer to the wrong product if its encoded identifier is incorrect.
