A student Bernie overheard a conversation and told his teacher Woodland about it and he experimented and he invented the bar code using morse code.
The bar code was invented in the United States. The first successful commercial use of the bar code system occurred in 1974 when a pack of Wrigley's chewing gum was scanned at a grocery store in Troy, Ohio. The technology was developed by Norman Joseph Woodland and Bernard Silver, who patented their design in the early 1950s. Their innovation laid the groundwork for modern bar code systems used worldwide today.
