Radio-Frequency Identification (RFID) is a technology that uses radio-frequency electromagnetic fields to transfer information from a tag to RFID reader for identification purposes. Passive tags do not require battery power. They derive power from the electromagnetic field generated from 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.

Access based RFID projects
RFID based security system
In security access system, RFID is in inductively coupling 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 authority of the person is also displayed on a LCD interfaced with the microcontroller.

Here an RFID tag is used, which is indirectly connected to the RFID reader using 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 card holder is shown on the display, indicating the attendance of the cardholder.

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 middle ware. The middle ware 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 authorisation for further processing can be granted or refused, depending on results received by the reader and processed by the database.

Automatic door lock system
The automatic door lock system consists of a reader, a controller and 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.

RFID projects in conveyance
Automatic car parking
RFID based car parking uses a microcontroller along with sensing circuits, monitoring entry and exit of cars. The car owners are allowed an 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.

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. Microcontroller senses the command given using keypad and receives signal from the IR receiver. It sends the data to the motor or buzzer depending upon the RFID card number and balance inside the card. Toll booth automation reduces human effort, improves security and avoids jam at toll centre.

Bus ticketing and accident information provider system
The passengers are counted using IR sensor and the distance travelled by passenger is calculated automatically using motor and u-slot sensor, and the corresponding amount is debited from 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 IR receiver. When 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 nearest retail shop.

The passengers will be provided with RFID tags. These tags contain a unique number. The passengers must enter the source and destination areas to travel. The system calculates the amount to be paid and displays it on the LCD. The user must show his RFID tag before the reader. The reader reads the number from the tag and records the ticket number on the tag number. The passenger should finally pay the fare. The RFID reader will be present even in the train. When the passenger enters the train, he should show his RFID tag once again at the reader. The reader reads the number and checks whether this number has taken the ticket or not. Buzzer indication will indicate if the passenger has not taken the ticket.

Intelligent vehicle control
This system deals with automatic vehicle speed limit on roads by solar powered RFID technology to control automobiles. An RFID reader present in the vehicle senses the vehicle speed limit on the tag as a reference speed input (attached to the speed limit signboard). Here, active RFID tag is used in the signboard which is battery powered from a solar panel. This reference speed is given to the electronic control unit. Meanwhile the vehicle speed sensor present in the wheel gives the actual speed of the vehicle on road. The output of this ECU unit is given to the proposed braking system present in the automobiles.

Petrol bunk automation
Each vehicle is fit 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 a valid data that is the amount should not exceed the balance available in the card. After dispensing petrol, information about available balance is sent to the user’s mobile phone using GSM.

When the card is brought near to the RFID module it reads the id code card and then compares with the id code present in the system. If it matches then the door gets opened in 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 user id and password using keypad. For a successful match, Id transaction is enabled, else denied. If the password does not match after three successive failures, the system gets locked and further transaction are denied. The transaction denial is indicated by a buzzer.

Event tracking system for sports
Each player will have a unique RFID tag connected to him/her to identify him when he/she has crossed the line. The system includes low frequency RFID reader and tags working at 125 kHz frequency to fetch the information from the player and process it through microcontroller. The name of the player who crosses the line first is then displayed on a LCD connected to it. For example, in racing game who have crossed the line first will be tough to judge if the distance between two racers is very less. In that case, we can use the RFID tags to identify who has crossed the line first.
