RFID based Attendance System with Applications

Radio frequency is an automatic identification process used for transmitting data between an RFID tag and RFID reader with the help of radio-frequency electromagnetic fields. The RFID tag is a device used to store data of any stuff, persons, books, animals, etc.  RFID tags are of different types some tags can be placed near to the RFID reader and some can read from far away distances beyond the line of sight of the reader.

There are different types of RFID systems  in the market that consists of an antenna, transceiver and a transponder. These systems operate at different frequency ranges like low frequency (30-500 kHz), mid frequency (900-1500 kHz) and high frequency (2.4-2.5GHz). Let us see one of the example based application of  RFID-based-attendance-management system in brief.


RFID Based Attendance System

The aim of this project is to maintain the record of the students’ attendance by using RFID tags. Each student is issued with his/ her authorized tag, which can be used for swiping in front of the RFID reader to record their attendance.

In most of the colleges and schools,attendance is recorded manually – such a process consumes lots of time. In this proposed system, attendance system is implemented by using advanced wireless technology “RFID”. Only the authorized students are provided with the RFID tags. This tag consists of an inbuilt integrated circuit for storing and processing information.

Microcontroller

AT89C52 Microcontroller from 8051 family is used in this system. It consists of four ports and 40 pins.

PCBWay

Oscillator Circuit

Oscillator circuit is connected between the 18 and 19 th pin of the microcontroller and consist of an oscillator with a frequency of 11.0592 MHz and two capacitors of 33pF.

Preset Circuit

The 9th pin of the microcontroller is RST pin, which is reset pin. This preset circuit comprises a switch, a capacitor of (10u) and a resistor of 10k. When the switch is pressed, the RST pin is connected to the power supply(Vcc) and the microcontroller gets reset.

LCD Display

The LCD display is used for displaying the data. It consists of 16 pins: three pins are connected to the power supply, and the remaining pins are connected to the port 2 of the microcontroller.

RFID Reader

The RFID reader is a module with RFID reader and antennaIt is small in size and integrates with any sort of hardware design. It is used to read the data  stored in the RFID tags.

Circuit Working

The data stored in this tag is referred to as the identification and attendance of the person. Once the student places the card in front of the RFID reader, it reads the data and compares the data stored in the microcontroller which is programmed by using Embedded C language. If the data matches, then it displays the information on the LCD. This RFID attendance system also makes use of the status button for retrieving the status of students’ attendance, which is interfaced to the microcontroller. By using this advanced concept, a lot of time can be saved as all the students’ attendance information is directly stored in the database.

Related RFID Applications

In addition to the above discussed project, here we are giving some more applications of RFID system for the reader for understanding purpose.

RFID Technology for Device Control and Authentication in Industries

The system is designed to provide security in an organization by allowing only the authorized persons to access the secure area. The main priority is the security in any organization. The authorized persons are assigned with  RFID tags that allow them into the secured premises.

RFID Technology Based Device Control and Authentication

The RFID tag consists of an integrated circuit,  which is used for storing and processing the data, modulating and demodulating the radio frequency signal that is to be transmitted. When a person shows the RFID tag in front of the RFID reader and the reader reads the data and compares the data stored in the system. If the data matches with the stored data, the system authorizes the person and allows  to enter into the secured area so that the person can take control of various devices. The system also displays the result on the LCD. If it finds the provided information mismatched then, it alerts an unauthorized entry with a buzzer sounds as an indication of entering or providing wrong information.

RFID Technology For Books Tracking in Libraries

RFID Technology For Books Tracking in Libraries

Searching and arrangement of misplaced books is a difficult task often carried out by the library personnel. Many a times Librarians busily search the improperly placed books or books wrongly placed by the library users and students in the library of a school, office or college. And often find this task very difficult. To overcome this problem, an RFID based intelligent book tracking system has been developed for monitoring the books in the library through wireless communication between the RFID reader and the books. This system consists of RFID tag and RFID reader to detect the information about the books placed in the library.

RFID Technology for Intelligent Tollgate System

The proposed system performs the following actions such as detecting, billing and accounting for vehicles as they pass through a toll gate within the frequency range between 30 kHz and 2.5GHz. In this system, an RFID tag is programmed with the vehicle owner’s information in the form with an EPC (electronic product code) that can ensures to read the data at certain distances and detects the vehicle in order to enhances a transaction.

A Passport system can become intelligent enough by the implementation of RFID technology to it. In this system, passport service issues RFID tag to eligible citizen, which contains passport details like name, address, nationality, passport number, and other relevant data. During the time of authentication, the RFID card reader reads that information and compares it with the data stored in the passport database. If it finds to be matched, then it will allow for further precedence,otherwise it alerts the authorities as fake details.

This is all about the RFID based attendance system project and RFID based applications. Any further help regarding this sort of projects or any other latest electronic or electrical projects, please contact us by commenting in the comment section given below.

    Hi Sam Kenny, the price of the project is different because the international project standards are not the same as Indian standards. Also logistics is an added cost factor for International shipments. The circuit diagram, code, component list, documentation and other information could be shared with you when you purchase the project.
    For customization of projects please email us on team@elprocus.com
