Radio frequency identification (RFID) is an emerging and evolving technology designed to automate and improve the efficiency and accuracy of the asset management process wherein the assets are identified and tracked. Radio frequency identification systems are used in a wide variety of applications, and provide convenient mechanisms for the tracking, identification, and authentication of persons or objects. RFID technology provides an alternative to bar code reader technology for distinguishing and recording items for purchase. Radio frequency identification tags and labels are widely used to associate an object with an identification code. Tags are devices that can come in many sizes and form factors, but are usually small and lightweight. A typical RFID tag includes RFID circuitry and an antenna by which signals are received from or transmitted to an RFID reader located within the operating range of the RFID tag. The tags respond to the interrogating RF signal from the RFID reader to retrieve the information stored in their memory. Tags are commonly used as portable data devices that wirelessly communicate with RFID readers at distances ranging from a few millimeters to several meters. Radio frequency identification systems generally use a fixed position base station capable of reading portable tags attached to personnel, assets, or other objects. RFID devices generally have a combination of antennas and analog and/or digital electronics, which may include for example communications electronics, data memory, and control logic. An RFID system typically includes one or more readers deployed at selected locations in an installation. During operation, the RFID circuitry receives a signal communicated from the RFID reader and generates a signal which is communicated back to the RFID reader.
