barcode
BAR-kohd
/ˈbɑːrkoʊd/

Specifically refers to the visual pattern of lines and spaces that can be scanned electronically to retrieve product information and price.
The story behind the word. The word 'barcode' is a compound of 'bar' (referring to the parallel lines) and 'code' (a system of symbols used to represent information). The concept emerged in the 1940s, but the first commercial barcode was scanned in 1974 on a pack of Wrigley's chewing gum, revolutionizing retail inventory and checkout processes.
