Barcode readers


A barcode is a graphical language that allows the representation of a data, number or text, by a series of lines (or small squares, such as for QR codes, for example) in a way that this can easily be read by an automatic system by means of special devices that uniquely recognize the initial data.

This technology is used in many fields for data transmission related to product traceability, such as storage or supply chain information, how to identify the lot and the production phases, tracing the origin of the item, or – as for QR codes – referring to web pages to provide the user, for example, food or tourist information, or product traceability data.
