Who invented the barcode?

Did you know that the barcode, a universally recognized product labeling system, was invented by Bernard Silver and Norman Josef Woodland on April 3, 1973? The barcode is a key tool today, providing information about products to both professionals and consumers alike.

Interestingly, the earliest attempt at product labeling dates back to 1948 when Bernard Silver, then a student in Philadelphia, developed a system for labeling products using glowing ink. However, this initial attempt was unreliable, expensive, and not practical. Silver continued to refine his idea and eventually teamed up with Norman Josef Woodland, resulting in the invention of the linear barcode. The two friends patented their invention and the rest is history. It’s worth noting that unlike the modern-day barcodes which are rectangular in shape, the earliest barcodes were circular.
