According to The Economic Times, the barcode originated from a simple problem faced by a supermarket in 1948. A grocer wanted a faster way to tally inventory and check out customers, leading to a sketched concept of lines and spaces. That idea, eventually developed by graduate students Norman Woodland and Bernard Silver, laid the groundwork for the Universal Product Code (UPC) that would later transform retail worldwide. The story was highlighted by Google News in a recent feature on retail barcodes.
The barcode system was first patented in 1952, but it took decades for the technology to become commercially viable. The first product scanned with a UPC barcode was a pack of Wrigley’s gum in 1974 at a Marsh supermarket in Ohio. From there, barcodes spread rapidly, enabling efficient supply chain management, accurate inventory tracking, and faster point-of-sale transactions. Today, billions of barcodes are scanned daily, and the technology continues to evolve with 2D codes like QR codes and the GS1 Digital Link standard.
The barcode’s invention is a classic example of how a simple observation can lead to a global industry standard. Its impact extends beyond retail to healthcare, logistics, and manufacturing, where it improves accuracy and efficiency. As the retail sector moves toward more advanced identification methods, the barcode remains a foundational technology that quietly powers commerce.
