George Joseph Laurer III (September 23, 1925 – December 5, 2019) was an American engineer for IBM at Research Triangle Park in North Carolina. He published 20 bulletins, held 28 patents and developed the Universal Product Code (UPC) in the early 1970s. He devised the coding and pattern used for the UPC, based on Joe Woodland's more general idea for .
At IBM, Laurer was assigned the task of developing barcode for use in grocery stores. Initially, IBM envisioned a circular bullseye pattern as proposed by Joe Woodland in 1940s. Laurer realized that the pattern was ineffective because of smearing during printing. Instead, he designed a vertical pattern of stripes which he proposed to his superior in 1971 or 1972. This change was accepted by IBM management and Laurer then worked with Woodland and mathematician David Savir to develop and refine the details. These included the addition of a check digit to provide error correction. In 1973, the IBM proposal was accepted by the Symbol Selection committee of the Uniform Grocery Product Code Council, a consortium of grocery store companies.
The Universal Product Code has bit patterns at the beginning, middle and end of the barcode called "guard bars" and these have been interpreted as the digits 666. When he first developed the code, Laurer noticed that the digit 6 appeared several times and that this might be interpreted as the number of the Beast, as his daughter was studying the Book of Revelation. When the codes started to appear in stores, there were protests and an urban legend developed. Laurer addressed this on his website:
As of 2019, UPC barcodes were being scanned more than 6 billion times each day, according to GS1.
