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. The 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 project ideas students always find them simple and interesting. There are many such projects available on the internet. We have listed down the top 20 simple RFID project ideas.

RFID project ideas for Security

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.

Attendance System

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.

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.

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.

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.

Railway reservation

The passengers will be provided with RFID tags. These tags contain a unique number. The passengers have to enter the source and destination areas to travel. The system calculates the amount to be paid and displays it on the LCD. The user has to 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 has to finally pay the fare. The RFID reader will be present even in the train. When the passenger enters into the train, he has to 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.

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

RFID project ideas for Banking system

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.
