Attendance System through RFID

Project Title

Attendance System through RFID

Project Area of Specialization Internet of ThingsProject Summary

We are going to design a system known as “Attendance system through RFID” . The strong reason to design this wireless attendance system with the attributes to maintain records of attendance and students identification using RFID technology .To propagate advance concepts of programming techniques, hardware interfaces and wireless communication in students through project based learning. Where as RFID is a technology that is used to collect information automatically by Radio Frequency data communication between a versatile object and an RFID reader to identify and track them. RFID system consist of three components (RFID reader, RFID tag, Antenna). (a) RFID reader: It can be use as remort storage unit where one can read and write information without contact. (b) RFID tag: They are passive, which denotes that the RFID module must design an electromagnetic field in order power the tag. (c) RFID Antenna : It receives the power from the electromagnetic filed. When the tag is placed near the reader, due to the induced mutual inductance energy, data is transferred to reader. Reader then transfers data to the microntroller. Microcontroller checks for the data continuously, if any data is received, microcontroller compares the data in data base. In this system, each student is issued an RFID tag. Controlling unit is in the institute. Whenever the card is placed near the reader, it will take the attendance.

Project Objectives

The main objective of the system is to uniquely identify and to make attendance for a person , this require a unique product which has capability of distinguishing different person . This is possible by the new technology RFID (Radio frequency identication). The main parts of an RFID system are RFID tags (with ID nummbers ) , and RFID reader for reading RFID tags and a LCD to display , objective of RFID based Attendance System project is use to take attendance for student in school, college, and university. .Microcontroller does the task of storing the attendance of the respective person in the microcontroller memory and RFID will read the card tags and will mark the attendance . we can also increase the range of RFID reader so that reader can detect tags from distance the data can be saved and store in computer . The aim is to save time and no energy required and to improve security measures for accessing facilities and improve focus on attendance as this have been rising issues today .

Project Implementation Method

•RFID based attendance system consists of RFID Reader, RFID Tag, LCD display and microcontroller unit. RFID can be interfaced to microcontroller through USART. Data is transferred from RFID cards to reader and from there to microcontroller.Radio frequency technology is used in many applications. RFID tags are of two types – 1) Passive Tags and 2) Active Tags. Passive tags contain 13 digit number tag inbuilt in it, where as active tag is read/write tag i.e. one can read from the tag and write to the tag. This project uses passive tag.In real time, one can issue active tags to the students, with their roll numbers as their tags. RFID reader contains a copper winding in it. This winding acts as an antenna.When the tag is placed near the reader, due to the induced mutual inductance energy, data is transferred to reader. Reader then transfers data to the microntroller. Microcontroller checks for the data continuously, if any data is received, microcontroller compares the data in data base.RFID module communicates with the controller using USART, where USART is a communication protocol. USART is acronym for Universal Synchronous and Asynchronous Receive and Transmit.Serial data can be transmitted from RFID module to microcontroller using UART. ATmega8 microcontroller has USART registers internally. One should declare these registers in order to transmit or receive data serially.LCD display is connected to Port B of the microcontroller. Interfacing of LCD in 4 bit mode is in to microcontroller which is shown in the circuit diagram. D4 – D7 data pins are connected to the PB0 – PB3 pins of microcontroller.RS pin is connected to PB4, RW pin is connected to PB5 and enable pin is connected to PB6 of microcontroller. To display data on LCD, initially set the LCD in 4bit mode. Then make Rw pin low, RS pin high, enable pin high. Send the data on data pins and make enable pin low. 

•How to Operate RFID Based Attendance System Circuit?

•After making all the above connections, Switch on the circuit.

•On LCD it is displayed “PLEASE SWIPE THE CARD”.

•Place the RFID tag near the reader.

•Reader then reads the data in the tag and transmits to the controller.

•Microcontroller compares the tag with the database. If the tag is matched LCD displays “authenticated” and takes your attendance

•Now place another card which is not present in the database and check for authentication.

•Now LCD displays “Unauthorised” and it will never take the attendance.

•In this way, we can use implement this circuit.

Benefits of the Project

The radio frequency identification (RFID) systems are being popular from  several years because  of some reasons such as economical, time saving, resource saving, reduced effort and easy to implement  A RFID tag is made up of an antenna, a wireless transducer and an  material  to implement the RFID technology in educational area to solve the problem of Identification method. There  are some instructors to mark attendance of their students in every lecture . The instructors are calling the name of each student and marking present or absent in from of his/her id and name over a paper. There are several problems associated with this method to marks attendance such as students only know their shortage if instructors are willing to inform them before the examination, time and cost consuming, proxy attendance, insecure, inefficient and inaccurate .  To developed a system to automate the attendance of the students using RFID technology. A tag is issued to each student at the time of his/her registration in the Central University of Technology. The university is currently marking attendance by using the web interface to mark attendance to replace the paper based traditional style to record present and absent. The main benefits of the web based attendance management system is that the record of attendance is accessible to the top management of academic institution in the form of detailed, summary and exception reports. These reports can be shared to the parents and guardians to take corrective actions. It is important to implement RFID attendance base attendance in all educational institution .RFID is emerging technology and is used in applications where authentication is needed.

Technical Details of Final Deliverable

The aim of this project is to design an RFID Technology based Attendance System using 8051 microcontroller, in which the attendance of students or employees is automatically recorded with the swipe of a card. The working of the project is explained here.When this circuit is powered ON, initially the microcontroller will display the message as Swipe the card on the LCD display. When the RFID reader detects the ID card, it will send the unique card no to the microcontroller via serial terminal.With the help of suitable programming, we need to compare the received card no. with the numbers that are already stored in the microcontroller or any database.Once, if any of these numbers are match with the received card no., then the corresponding name stored in that no. is displayed on the LCD display and also the attendance for the name stored in the corresponding number is marked.By pressing the button, the attendance recording will be closed and the details are displayed on the LCD repeatedly until the microcontroller has been reset.
