This drawback always causes so-called "Bullwhip Effect". In order to improve the supply chain efficiency, Point of Sale (POS) is often applied. However, a POS system merely offers final sales and inventory information, which is usually insufficient for managers to make proper decisions. Therefore, to further investigate the customers' behaviors from goods selling status data besides POS data is strongly needed.
Recently, successful applications of Radio Frequency Identification (RFID) in supply chain have made enhanced POS system possible. Moreover, in a demand chain which is built based on "Pull" fashion, RFID technology can even play more important role. RFID not only record goods selling data in demand chain, but also perform to communicate between goods selling status and the information system in dual ways. Compare to the traditional Bar Code system, RFID has more capability to offer real-time information and more traceability to goods selling status.
This research aims at proposing a RFID reading status display system, which utilizes the characteristics of reading and writing functions in RFID. The proposed system can gather the real-time goods selling information and trace every product status in the demand chain. In the study, a simulation model and its testing experiments were proposed for system proving and evaluation. Via the design of the simulation model, the information can be recorded when the customers pick up products on the shelf, meanwhile, the behaviors of consumers can also be recorded to reduce any possible goods selling loss.
Via the introduction of RFID, this research offers a feasible solution to enhance the applications of any traditional POS. The enhanced POS system combining with RFID devices not only offers the goods selling status information, but also helps decision makers; moreover, due to the supervising of several RFID devices, the loss from stealing can be decreased.
