Radio Frequency Data Communication Applications in the Construction Industry
Abstract
Bar codes have gained increased importance in many industries due to their proven cost savings. By 1987 the bar code market in the U.S. had grown to $740 million. They have been used to track overnight mail packages, mark computer circuit boards, track tools and apparels, trace blue print status, and numerous other applications. Bar codes have traditionally been used as a passive identification symbol on items. The symbol is read by a scanner which stores the information encoded by the symbol until it can be downloaded into a computer. However, bar codes have recently been combined with radio frequency equipment to add an interactive, real-time dimension. Users can now read from and write to a computer database from remote locations without any physical link between the operator and computer. And when integrated circuits are substituted for the bar code symbol, hundreds and even thousands of bits of information can be stored in and read from the chip. This new technology is known as radio frequency data communication.
