There exist several technologies serving the same purpose of quickly and accurately capturing data. The key automatic data collection technologies include bar coding, magnetic stripe, radio frequency data communication, radio frequency identification, voice data collection, machine vision, optical character recognition, and smart cards.
Bar coding is an industry standardized symbol consisting of bars and spaces of various widths that are read by optical scanning devices. The width and position of the bars are actually coded combinations of numbers, letters or punctuation, used to "identify the item, its producer and any other piece of information necessary to control its movement".1 (Anonymous, "Industrial Engineering's 1992 Automatic Identification Buyer's Guide". Industrial Engineering, p.BG1) The item is scanned, all its data is transmitted directly into a computer via electrical impulses, generated from light reflections from the bars and spaces. The impulses are measured by a decoder, translated into binary code then transmitted to the computer. This technology is optimal for rapidly moving items commonly found on conveying systems within the retail and manufacturing arenas.
Magnetic stripe technology however, was initially instituted by the financial services industry to identify accounts and as a means of security. The magnetic stripe records greater volumes of information than many of the other aforementioned technologies, including bar coding. It provides a flexible format, with higher durability, and is highly secure. Data is encoded using electromagnetic charges that are read by a decoder, translated into numbers and letters, immediately identified by the computer. This technology is currently being applied to employee ID badges, debit cards, boarding passes for commercial flights, filling stations and some manufacturing applications. Future technical refinements include increased data storage on the magnetic stripe, resistance to...
