This year marks 50 years since the first ever scan of the modern UBC barcode, on a 10-pack of chewing gum in a grocery store in Troy, Ohio.
Fast forward to 2024 and more than 10 billion barcodes are now scanned every day around the world.
Jordan Frith is a self-confessed barcode lover. He's written a book on the subject, Barcode - and has the barcode of that book tattooed on his left arm!
He speaks to Emile Donovan about how the barcode changed the world.
