Radio Frequency Identification (RFID) is a general term that is used to describe a system that transmits the identity (in the form of a unique serial number) of an object wirelessly, using radio waves. RFID Technology is evolving as a major enabler for tracking goods, managing assets, and monitoring movement of vehicles around the world.

RFID (Radio Frequency Identification) is a technology where information can be read from and/or written to a microchip without contact using Low Frequency (LF), High Frequency (HF) magnetic induction or Ultra High Frequency (UHF) transmission and reflection. A typical RFID System consists of the following four components.

• RFID tags or transponders
• RFID readers or transceivers
• RFID middleware
• RFID software applications

Radio Frequency Identification (RFID) has been used in many applications e.g. Attendance System, Access Control System, File Tracking System, Asset Tracking, Inventory Management System etc.
