It started with a problem.
Before the familiar supermarket scan, retailers needed a practical way to identify products at checkout. IBM engineer George Laurer led the team behind the rectangular Universal Product Code. The design turned a product identifier into a pattern a scanner could read. The first retail UPC scan took place in 1974: a pack of chewing gum at a supermarket in Troy, Ohio.

The change extended beyond a faster checkout. Linking purchases to product identifiers helped retailers understand sales and manage inventory. A small printed symbol connected a physical item to information a business could use.
What a builder can learn.
Our interpretation: a useful innovation can live in the agreement between businesses. A shared identifier makes separate activities easier to coordinate. For a founder, the interesting question is where people still translate the same information by hand. That repeated work may reveal a missing common language.
A door still open.
A hypothesis to explore: smaller businesses could benefit from a shared vocabulary for repair history, reusable packaging, or product condition. Start with one handoff between two partners. Test whether a common record removes work before building a large platform.
What does your team repeatedly identify, retype, or reconcile—and what would a shared language change?
