Who Invented the Barcoding System?
George Laurer invented the 12 digit UPC-A Barcode system when he was working for IBM. He is supportive of reseller barcode numbers like ours and does not like the way GS1 has decided to restrict entry to the market by charging high fees.
Look here for CD barcodes, DVD barcodes, ISBN book barcodes and ISSN magazine barcodes.
