According to a recent article on MSN , sourced from Google News , the barcode—a ubiquitous technology in modern retail—was first conceived decades before it became commercially viable. The idea originated in the early 20th century, but the necessary scanning and data processing technology did not exist to make it practical.
The article traces the invention to a 1932 student thesis at Harvard Business School, where a system of drawing lines in the sand to encode product information was proposed. However, the lack of affordable laser scanners and computers delayed any real-world implementation for nearly 40 years. It was not until the 1970s that the Universal Product Code (UPC) was standardized and adopted by supermarkets.
Today, barcodes are an essential part of global supply chains, enabling fast checkout, inventory management, and data tracking. The story serves as a reminder that groundbreaking ideas often need time for the surrounding technology to catch up before they can transform industries.
