Abstract

While possibly on a larger scale, many of the systems in use today are addressing the same problems that have been around for one-hundred years or more. For example, the precursor of the bar code system for pricing retail merchandise might have been the "secret code" used by merchants around the turn of the century. J. L. Nichols, A.
