RFID Projects Ideas for Engineers

Radio-frequency identification (RFID) is a technology that uses radio-frequency electromagnetic fields to transfer information from a tag to an RFID reader for identification purposes. Passive tags do not require battery power. They derive power from the electromagnetic field generated by the reader. Some tags are also available which have their own power source.

When it comes to RFID projects, students always find them simple and interesting. There are many such RFID projects available on the internet. We have listed down the top 20 simple RFID projects for you to try.

(To access detailed information about a specific project, simply click on the name of the project below)

1. RFID-based Security System

In a security access system, RFID is inductively coupled with the reader. When a card is swiped against the reader, modulated data from the card is sent to the reader which in turn is fed to the microcontroller.

The card used is the identity card for a particular person and carries his/her details. If this data matches with that stored in the database of the microcontroller, the person is given access to the secured area.

This is indicated by a lamp being switched on. The status of the authority of the person is also displayed on an LCD interfaced with the microcontroller.

More details about this are available at RFID based Security system

2. Attendance System

Here an RFID tag is used, which is indirectly connected to the RFID reader using the inductive coupling method. As the tag or the card is swiped against the reader, the tag receives a carrier signal from the reader and in turn modulates the carrier signal and sends it back.

The reader receives this modulated signal and sends this data to the microcontroller. The microcontroller compares this data with the existing data and on pressing the status push button, the status of the cardholder is shown on the display, indicating the attendance of the cardholder.

3. Access Control System

An RFID reader emits a low-level radio frequency magnetic field that energies the tag. The tag responds to the reader’s query and announces its presence via radio waves, transmitting its unique identification data.

This data is decoded by the reader and passed to the local application system via middleware. The middleware acts as an interface between the reader and the RFID application system.

The system then searches and matches the identity code with information stored in the host database or back-end system. In this way, accessibility or authorization for further processing can be granted or refused, depending on results received by the reader and processed by the database.

4. Anti-theft Auto Security System with an Immobilizer

The immobilizer uses the active RFID technology where the tag is generated with comparatively large character sets. The receiving unit is intelligently integrated into three control circuits in the vehicle, namely, the ignition circuit, power control unit, and automatic gear changing system, enabling it to bring the vehicle speed down to zero in a safe step-by-step manner.

The anti-theft auto security system proposed here was tested under different weather conditions and possible signal distortion situations to verify its reliability.

5. Automatic Door Lock System

The automatic door lock system consists of a reader, a controller, and a door lock. Here a reader reads the RFID tags, a controller is used to accept the data from the reader and control the o/p of the door lock.

The RFID reader is placed on the outside of the door and it is detached from the controller confidentially so no one can avoid the security by breaking open the RFID reader and trying to short circuit the reader.

The controller of this project receives serial information from the RFID reader and controls the door lock and the LED.

6. Automatic Car Parking

RFID-based car parking uses a microcontroller along with sensing circuits, monitoring the entry and exit of cars. The car owners are allowed entry only when their RFID card is swiped. The amount in the card automatically gets reduced with a display indication besides indicating the available number of parking.

An H-bridge arrangement operates the entry and exit boom motors operating clockwise and anticlockwise for opening and closing. A buzzer sound comes while the card is swiped.

Upon every entry of a car, the parking availability gets reduced by one number while every exit increases the number.

7. Toll Booth Automation

The microcontroller reads the RFID card number from the RFID reader. It sends this data to the LCD so that the person operating this product reads various informative messages.

The microcontroller senses the command given using the keypad and receives a signal from the IR receiver. It sends the data to the motor or buzzer depending on the RFID card number and balance inside the card.

Tollbooth automation reduces human effort, improves security, and avoids jams at toll centers.

8. Bus Ticketing and Accident Information Provider System

The passengers are counted using an IR sensor and the distance traveled by the passenger is calculated automatically using a motor and u-slot sensor, and the corresponding amount is debited from an RFID card.

In addition to that, the occurrence of accident information is automatically transmitted to the nearest hospital using GSM and GPS. IR transmitter and receiver are placed straight to each other, so the transmitted IR ray is received by the IR receiver. When the passenger crosses the IR transmitter and receiver, the rays received will be interrupted.

Here the microcontroller, Atmel 89C52, has flash-type reprogrammable memory. The RFID tag is rechargeable and can be recharged at the bus depot or the nearest retail shop.

9. Petrol Bunk Automation

Each vehicle is fitted with a prepaid card. When a car arrives at the gate, the RFID reader reads the card. The gate is opened only when the card is valid. Once entered the user will be shown the balance amount available on the card and he must select an option to dispense the fuel.

The system checks whether the user has entered valid data that is the amount should not exceed the balance available on the card. After dispensing petrol, information about the available balance is sent to the user’s mobile phone using GSM.

10. RFID based Passport

The project designed is an authentication system where the passport holder is authorized through RFID technology. The passport holder would have an RFID tag that contains all the passport details like name, number, nationality, etc.

This tag has to be swiped over the reader and the information thus read is provided to a microcontroller.

This information is matched with the one stored in the microcontroller, if the data matches microcontroller displays a confirmation message otherwise displays a denial message on an LCD screen.

The status of a particular person can also be obtained through a status button in the system.

11. Airport Luggage Security Scanning System

Read-only tags are typically passive and are programmed with a unique set of data that cannot be modified.

The reader has three main functions: energizing, demodulating, and decoding.

The antenna emits radio signals to activate the tag and to read and write data to it. Here we are using RFID based security scanning system to check the luggage in highly secured areas like airports, railway stations, in various places where security is the primary concern.

Here we are placing the luggage bags that are to be scanned.

13. Banking System

When the card is brought near to the RFID module it reads the ID code card and then compares it with the ID code present in the system. If it matches then the door gets opened in the clockwise direction and the person gets in.

The door is automatically closed at a defined time. Every time we make a transaction, we need to enter the user ID and password using a keypad. For a successful match, the ID transaction is enabled, else denied.

If the password does not match after three successive failures, the system gets locked and further transactions are denied. The transaction denial is indicated by a buzzer.
