History of the Barcode

June 9, 2011

Gizmodo is usually the site where I read about updates to game systems or crazy slingshots that can shoot watermelons, but their article – Where Do Barcodes Come From – offered an interesting history on quickly capturing data of which I was definitely unaware. It’s a great read and helps provide insight into a very major part of most people’s lives.

Much of the article covers the precursor to grocery and retail checkout, and how it was originally intended to follow parts in manufacturing or track trains. For instance, I did not know that the first method used a Xenon white light to measure the length of red, white, and blue bands on passing trains to identify the owner. Could be why Honeywell’s new 2D Imager is called the Xenon.
