RFID technology and ePedigree are one of the solutions of the coterfait problem. This paper presents a medical information system application of controlled drugs with ePedigree and RFID technologies. This application fellows the Pedigree speciofication version 1.0 announced by EPCglobal in Fabray 2007. In the study we show a pilot system for tracking and tracing the controlled drugs in Taiwan and the performance from management view is also presented. We expect the prototype system would be merged into the production system of a hospital. Then speedup the information exchanges amoung the drug supply chain.
