circuit diagram of automated attendance system using rfid and ivrs

Attendance needs to be taken at various places including colleges, school for students and in the industries for the login logout time of employees. Radio Frequency Identification (RFID) based attendance management system can be used in any college or university or company. Main objective of RFID based Attendance System project is to take the attendance of students or employees. Microcontroller does the task of storing the attendance of the respective person in the microcontroller memory.

Attendance Register

The existing attendance system is manual and it is taken on paper and it consumes lot of time. As we aware that many traditional “Attendance system” uses attendance register to note down the attendance. It has less accuracy. Also the administrative person needs to maintain the attendance papers / sheets. In many industries attendance register is used to note down the attendance of their employees. In school attendance is taken on roll call musters and in colleges attendance is taken by respective professors. Problem with existing attendance system is that wrong attendance can be entered. For example, in an industry, employee can enter invalid/incorrect login logout time. They can come at 10am and can enter time as 8 am. Also in colleges one student can give proxy attendance of another student. Probability of this is very less but it does happen.

To avoid all such problems, we have implemented automated attendance system which utilizes RFID cards. Thus it is a RFID based attendance system. In this system each user, student or employee will have a RFID card. And RFID reader will be placed on the door or the entry gate of the company or on the door of the classroom or school. Whenever employee wants to enter in the office; he/she has to show the RFID card to the reader. He/she has to take the RFID card near to the RFID reader. Then the RFID reader will note down the RFID card number and the time at which the employees / student has logged in. And in the same manner while leaving employee/student has to show the card. So the exit time will be noted.

Commonly used RFID cards are of the size of credit card and are white in color. However now days RFID cards are also available in small or RFID key tags are available. These key tags can be connected with the keychain. And normal RFID card can be stick together with the ID-card of employees or students. Or we can even print the ID-card information on the RFID card itself. This means that there are no extra efforts required or no extra trouble is caused for carrying this card since students and employees always carry their I-cards in college and industries respectively. Credit card needs to be swapped or need to be inserted inside the credit card reader machine. But RFID card does not need to be inserted, user just needs to take it near the RFID reader. So student/employee can even keep it in wallet and they can just take wallet near the RFID card reader without removing card from wallet. This way RFID module will read the card information.
