The first barcode was invented in 1949 by Norman Woodland and Bernard Silver, two engineers at Drexel University. They developed a barcode system called the "bullseye barcode," which used concentric circles to represent data. However, it was not until the 1970s that the modern barcode, known as the Universal Product Code (UPC), was developed. The UPC was introduced in 1974 and quickly gained popularity in the retail industry.

Researchers at ResearchGate have noted that the "ease of use" and "perceived usefulness" are key drivers in how quickly industries adopt these systems. Impact Across Major Industries Types of Barcodes: Choosing the Right Barcode - Scandit

The barcode is the modern seal of approval. Before it, an apple was an apple. A shoe was a shoe. Each had its own small, messy identity: the bruise, the scuff, the slight asymmetry of the hand. The barcode arrived to cure that sickness of uniqueness. It says: You are not an object. You are a unit. You are a line item.
