On a Sunday afternoon in 1971, an I.B.M. engineer stepped out of his house in Raleigh, N.C., to consult his boss, who lived across the street. “I didn’t do what you asked,” George Laurer confessed.
Laurer had been instructed to design a code that could be printed on food labels and that would be compatible with the scanners then in development for supermarket checkout counters. He was told to model it on the bull’s-eye-shaped optical scanning code designed in the 1940s by N. Joseph Woodland, who died last month. But Laurer saw a problem with the shape: “When you run a circle through a high-speed press, there are parts that are going to get smeared,” he says, “so I came up with my own code.” His system, a pattern of stripes, would be readable even if it was poorly printed.
That pattern became the basis for the Universal Product Code, which was adopted by a consortium of grocery companies in 1973, when cashiers were still punching in all prices by hand. Within a decade, the U.P.C. — and optical scanners — brought supermarkets into the digital age. Now an employee could ring up a cereal box with a flick of the wrist. “When people find out that I invented the U.P.C., they think I’m rich,” Laurer says. But he received no royalties for this invention, and I.B.M. did not patent it.
As the U.P.C. symbol proliferated, so, too, did paranoia about it. For decades, Laurer has been hounded by people convinced that he has hidden the number 666 inside the lines of his code. “I didn’t get the meat,” Laurer said ruefully, “but I did get the nuts.”

You worked at I.B.M. in the 1970s and then helped promote the U.P.C.?
Yes, I started the seminars where we invited people from the grocery and labeling industry into I.B.M. We were there to reduce their fear.
What were they afraid of?
They were afraid that anything that didn’t work right would reflect badly on them — particularly if it was only their own package that wouldn’t scan. The guy from Birds Eye said, “My stuff always has ice on it when it goes through the checkout.” So we put his package in the freezer and took it out and showed him how it scanned perfectly.
Why are you still so interested in the history of the U.P.C.?
Let me put it this way: What bigger impact can you have on the world than to change the way everyone shops?
