An RFID based security system is a type of access control system that uses RFID technology to identify and authorize individuals. RFID systems typically consist of RFID readers, RFID tags or cards, and a control panel. RFID technology can be used in a variety of security applications, including access control, asset tracking, and identification. It offers several advantages over traditional security systems, including the ability to quickly and accurately identify individuals, the ability to track the movement of individuals or assets, and the ability to operate remotely without requiring physical contact.

Here is how an RFID based security system might work:

1. An individual approaches a secured area, such as a door or gate, that is equipped with an RFID reader.
2. The RFID reader sends out a radio frequency signal, which activates an RFID tag or card that the individual is carrying.
3. The activated RFID tag or card transmits a unique identification code back to the reader.
4. The reader sends the identification code to the control panel, which checks the code against a database of authorized codes.
5. If the code is on the list of authorized codes, the control panel sends a signal to the reader to unlock the door or gate and allow the individual to pass through. If the code is not on the list, the door or gate remains locked and the individual is denied access.

This technology can be used in a variety of settings, including:

1. Corporate offices: RFID systems can be used to control access to secure areas, such as server rooms or executive offices.
2. Government buildings: RFID systems can be used to control access to sensitive areas in government buildings, such as embassies or military bases.
3. Schools: RFID systems can be used to control access to buildings or specific areas within a school, such as classrooms or laboratories.
4. Hospitals: RFID systems can be used to control access to restricted areas in hospitals, such as drug storage areas or operating rooms.
5. Airports: RFID systems can be used to control access to restricted areas in airports, such as planes or luggage handling areas.
6. Prisons: RFID systems can be used to control access to secure areas in prisons, such as cell blocks or administrative offices.
7. Amusement parks: RFID systems can be used to control access to restricted areas in amusement parks, such as behind-the-scenes areas or VIP sections.
8. Events: RFID systems can be used to control access to events, such as concerts or conferences, by issuing RFID-enabled tickets to attendees.
