Main concept behind Radio Frequency Identification (RFID) based Security system is to allow the access only to autorized persons . RFid card has to be shown in front of the RFid reader, then the access is allowed or denied to the resptive person/RFid card.

Block Diagram:

RFid Based Security System

Description in detail:

It mainly consist of following blocks:

1. RFID Reader: It reads the unique rfid number from the RFID cards or rfid tag and sends it to microcontroller

2. Microcontroller: This is the CPU (central processing unit) of our project. The various functions of microcontroller are like I. Reading the digital input from RFID reader II. Turn on the buzzer for invalid card. III. Turn on the motor or relay if the card is valid.

3. LCD: We have used 16×2 alphanumeric Liquid Crystal Display (LCD) It can display alphabets along with numbers on 2 lines each containing 16 characters.

4. Motor: For valid card a motor is turned on to indicate the door latch opening

Applications and Advantages:

1. This project can be used in home or office.

2. Same project can be implemented in industry or educational institutes.

Future Development:

1. We can send this data to a remote location using mobile or internet

2. We can add the module of voice alarm system to indicate valid or invalid card entry.

Question and answers about this project:

Question: How many RFID cards are provided with this project?

Answer: We will provide 5 RFID cards. Entry will be allowed for 3 valid cards. And alarm/buzzer will be turned on remaining 2 cards.

Question: I want a rfid project which can read more than 200 tags at a time. I mean if I put bunches of rfid tags near to rfid reader it should read all tags successfully and show output on computer terminal (on PC) and i have all passive tags.

Answer: You have to take RFID card 1 by 1 near the RFID reader. Then only RFID reader will read the RFID cards. It can’t read bunches of tags. It can’t read the tags if bunch is kept in front of it. You have to pick one by one and take it near to RFID reader.

    How do i order this?

  • Sarumi Taiye says:

    Good afternoon,
    The RFID security based system, is it possible to have many cards because what i intend using it for f The card is to manage visitors i.e. monitor which floor the visitor is in a building such that if you’re issued the card to floor one at the reception and you now move to floor two, the RFID devices placed at strategic locations on each floor will trigger a buzzer which will attract security. The idea now is to configure the RFID cards that will be issued for each floor.
    My question now is that can i get a RFID security based system not yet programmed, which i will do myself but i want the kit to come with as many cards as possible because i never can tell number of visitors to expect at any moment.
    Would i be able to get the programming the chip kit? or what do you suggest if i cannot?

    • Microtronics Technologies says:

      Hi Sarumi Taiye, we would suggest you to use 2 different project kits on different floors. Each floor will have access only to limited cards. But your requirement of programming on yourself can not be satisfied because all our projects are pre-programmed.

  • thismi says:

    can u programmed two differnt functions by using rfid technique?for example one is automatic security system and attendence if not so tel me some suggestion

    • Microtronics Technologies says:

      Hi thismi, yes we can do that. We can combine the RFID security system and RFID attendance system. It can be called as RFID based attendance cum security system. In this system access will be allowed to that person which has valid RFID card and at the same time attendance will be marked.

  • Anshul says:

    can the same project available in C language instead of assemble language ????

  • Archana says:

    I need project on RFID system for library books to control from theft and circulation. Is it possible with your project equipments?


  • Ramandeep Kaur says:

    i want to ask u that this project is applicable for MTECH level.. if u have any more advise for me, just tell me.. I m 3rd sem student n i hv an urgent project to submit.. Plz reply me as soon as possible.

  • heena chauhan says:

    I want to make a rfid project on my own . So can I get your help. Can I contact you on mobile so that i can explain you what I am thinking .

  • Don says:

    Hi just wondering if a RTC chip could be added to the attendance sytem for checking what times each caard was logged in at I understand you may not be able to add it to these specific projects I would just like to know if this could be done as the 8051 is well know to be terrible at keeping time itself

    • Microtronics Technologies says:

      Hi Don, we don’t have RTC chip. But we can track the time of RIFD card access. We can do this by using internal timer of 8051 microcontroller. This project can be called as, “RFID based attendance cum security system”

  • joymano says:

    i would like to do this RFiD as a project so i need some codings using visuslbasic and back end as ms access .

    • Microtronics Technologies says:

      Hi joymano, We don’t have coding for VB and MS access
      We use Terminal (or Hyper Terminal) software on computer to view message.

  • Lenie says:

    Hi there ? Well i am kinda interested to learn more about rfid .. i was just wondering if how to connect an rfid with a database (mysql)? .. can you give better suggestions? hope you can help me. thank you very much !

  • amit says:

    how is possible to do compact key chain to detect alcohol taken by driver and use RFID for lock unlock the car? is it possible to do these two things with keychain?
