The first item ever scanned with a barcode was a pack of gum

On June 26, 1974, a small pack of Wrigley’s Juicy Fruit gum made retail history. At a Marsh supermarket in Troy, Ohio, cashier Sharon Buchanan passed the gum across a scanner, and the machine read its black-and-white Universal Product Code. The price appeared automatically, marking the first time a barcode was used in a real commercial checkout.

The moment was ordinary on the surface: a shopper buying gum. But it represented years of work by inventors, engineers, grocery executives, and manufacturers who wanted a faster, more accurate way to manage sales. Before barcodes, cashiers typed prices by hand, stores relied on stickers, and inventory tracking was slower and more error-prone. The UPC turned every product into data that could be read instantly.

Gum was a fitting first item because it was small, inexpensive, and common, the kind of product supermarkets sold constantly. Yet that humble purchase helped launch a system that now shapes nearly every part of modern commerce. Barcodes speed up checkout lines, reduce pricing mistakes, help stores reorder stock, and make supply chains easier to follow. From groceries and books to hospital supplies and shipping labels, the simple pattern of lines has become a global language.

The original pack of Juicy Fruit was not chewed or tossed away. It became a museum piece and is now part of the Smithsonian’s collection, preserved as a symbol of a quiet technological revolution. It reminds us that major changes do not always arrive with dramatic fanfare. Sometimes they begin with a beep, a cashier, and a pack of gum.

Today, scanning a barcode feels almost invisible because it is so routine. That is what makes the story memorable: one of the most important retail innovations began with one of the most ordinary purchases imaginable. And it changed shopping for everyone, almost overnight forever.
