Security Access Control Using RFID Projects System

Security Access Gate Control Using RFID Project

A present world for the purpose of security there is need to authorised person and to restrict their access to sensitive areas in the organisation. In such a way, suspicious persons can be caught which will surely improve the security level in the organisation. So here we introduced the RFID get control system which is mainly based on Radio Frequency Identification (RFID) technology.

RFID based gate control system we can control gate if valid car is pass then its open the gate if invalid car is there these is doesn’t allow him to enter in gate and get remain the close so there is no need of person to check each entry.

Block diagram:-

The system starts from the RFID card is a microchip combined with an antenna which is detected by the EM-18 RFID reader & sends the data i.e. type & no. of vehicle stored in 12 digit code form in the card to the AT89S51 micro controller to match with data base provided at get.

The AT89S51 micro controller then compares the signal with the stored value & displays on LCD. So the customer has to just swap his RFID card then micro-controller sends the signal to the dc motor which is used as get barrier which will open and close accordingly to car.

if the RFID card is invalid then the card will not have accepted and output will display on LCD and get will not open.
