RFID is an acronym for radio frequency identification, which is a wireless communication technology that is used to uniquely identify tagged objects or people. RFID is a very valuable business and technology tool. It holds the promise of replacing existing identification technologies like the bar code. RFID offers strategic advantages for businesses because it can track inventory in the supply chain more efficiently, provide real-time tracking, and monitor general enterprise assets. The use of RFID technology is expected to grow significantly in the next five years, and it is predicted that someday RFID tags will be as pervasive as bar codes.

TYPES OF RFID : |
- PASSIVE : No power to transmit signal , relies on readers |
- ACTIVE : Includes a power source to help transmit a signal

( Tamper - Memory LED - Buzzer - Temperature ) |
THE THREE CORE COMPONENTS OF AN RFID SYSTEM : |
An RFID system uses wireless radio communication technology to uniquely identify tagged objects or people. There are three basic components to an RFID system: |
1. A tag (sometimes called a transponder), which is composed of a semiconductor chip, an antenna,
and sometimes a battery
2. An interrogator (sometimes called a reader or a read/write device), which is composed of an
antenna, an RF electronics module, and a control electronics module
3. A controller (sometimes called a host), which most often takes the form of a PC or a workstation
running database and control (often called middleware) software
