General RFID Overview
Radio frequency identification (RFID) is a generic term that is used to describe a system that wirelessly transmits by radio waves the identity (in the form of a unique serial number) of an object or person. RFID enables this wireless data to be collected by readers from electronic tags attached to or embedded in objects, for identification and other purposes. RFID systems involve hardware, software, network and database components that enable information to flow from electronic tags to the organization’s information infrastructure, where it is processed and stored. Systems are application-specific. Some use passive, low-cost tags with short read ranges, mostly data on the network, and only small amounts of information on tags. Others use active battery-powered, high-performance tags with high data capacity or read ranges that can carry considerable data on tags without network connection. Technological developments are focusing on increasing real-time information of business processes, improved business performance and improved security and privacy.
