Bar codes

Bar codes are used for a lot of purposes from product coding and inventory control to providing electronically-readable tags giving supplemental information such as web links related to a place or thing.

The 1979 comedy book The 80's: A Look Back, giving a fake "future history" of the 1980s, had fake bar codes (in a square format) on every page, parodying a belief that this sort of thing (then being done in some computer magazines to provide scannable program code) would go mainstream. The book also had an article "Adieu, Print" about the demise of print publishing, which was a few decades ahead of its time.
