GS1 introduced the barcode in 1974. [8] A barcode encodes a product identification number that can be scanned electronically, making it easier for products to be tracked, processed, and stored. Barcodes improve the efficiency, safety, speed and visibility of supply chains across physical and digital channels.
For the end user, Code 128 barcodes may be generated by either an outside application to create an image of the barcode, or by a font-based barcode solution. Either solution requires the use of an application or an application add in to calculate the check digit and create the barcode.
George Joseph Laurer III (September 23, 1925 – December 5, 2019) was an American engineer for IBM at Research Triangle Park in North Carolina.He published 20 bulletins, held 28 patents and developed the Universal Product Code (UPC) in the early 1970s.
These barcodes only represent the digits 0–9, unlike some other barcode symbologies which can represent additional characters.
