Barcodes
Woodland and Silver were not able to put the concept into operation generally, but George Laurer, an electrical engineer with IBM, developed a scanner that could read the codes digitally and Woodland (also now with IBM) concentrated on stripes rather than his alternative but hard to print bull's-eye, after which the procedure started to become commercially usable. A similar barcode was introduced into a retail context by a large chain (Sainsbury's) in the UK in 1971, and the UPC barcode developed following Woodland, Silver and Laurer's system was tested commercially (in a supermarket in the USA) in 1974.
