PROJECT DESCRIPTION

The main objective of this project is to provide security in an organization by allowing only the authorized personnel to access the secure area. The security of any organization is a priority for the authorities.

The concern is for the physical property and also for the intellectual property. For this reason only the authorized person with a valid RFID tag is allowed into the secured premises. This tag contains an integrated circuit that is used for storing and processing information, modulating and demodulating the radio frequency signal that is being transmitted.

Thus, once the person shows the RFID tag to the card reader it scans the data present in the tag and compares it with the data present in the microcontroller. When the data matches with that in the microcontroller, the load will be turned ON which is operated by a relay being driven from the output of the microcontroller. If a valid tag is swiped then the system displays a message “AUTHORIZED” else it states “UNAUTHORIZED” and doesn’t allow access.

A lamp is used as an indication besides the LCD display. This project can be further enhanced by interfacing it with GSM technology. Any attempt for unauthorized access can be intimated to the security personnel through an SMS. It can also be interfaced with a finger print module to reduce the drawback of RFID system i.e. exchanging RFID tags.

Q & A
Q:  What is RFID?
A:  RFID stands for Radio Frequency Identification Device. It is a technology based identification system using tags to identify objects.
Q:  What is RFID card?
A:  RFID card is an accessory which has got a coil and a chip for the reader for data communication. While it is placed on the RFID reader device, it gets induced power from the reader and then the data present in the card is serially transmitted to the receiver.
Q:  Which type of relay is being used here?
A:  A 12V single contact relay is being used here in this project.
Q:  Is it possible to replace the existing load by a lamp?
A:  Yes, it is possible to replace the load by lamp, but limited to 200 W.
