PROJECT DESCRIPTION

The main goal of this project is to develop an RFID-based attendance system for industries or colleges. This system can be used to record the attendance of students/employees by using RFID tags that are provided to each student/employ.  With the authorized tag, employees or students can swipe the reader to register their attendance.  

In the current system,  attendance is usually recorded manually and it is a time-consuming process wherein attendance of each student is recorded by calling the roll number. The proposed system is designed with the RFID tag to make note of every student/employ entering and exiting a college or a company.  The tag contains an integrated circuit to store, process and verify the information by modulating and demodulating the radio frequency signal being transmitted.

This system works based on the microcontroller of the 8051 family. The project uses an RFID reader which is directly interfaced to the microcontroller for reading the details like name, roll no. or ID, nationality, etc., of an authorized person from the RFID tag. A status button is interfaced to the microcontroller for displaying all the information of the person such as name, age, roll number, etc., on a 16*2 LCD screen.

An RFID tag is used along with the reader to input the details of the employee/ student for tracking their attendance. When the RFID is swiped on the reader, the data of the particular tag is compared with the data in the microcontroller (interfaced to the reader) to identify the user. An LCD is interfaced to the microcontroller to display the name of the user. Additionally, a status button is used to display the overall attendance to the user.

The future scope of this project can be enhanced by adding features like a provision for sending SMSs to parents regarding the daily attendance of students.

Q & A
Q:  What is RFID card?
A:  RFID card is an accessory which has got a coil and a chip for the reader for data communication. While it is placed on the RFID reader device, it gets induced power from the reader and then the data present in the card is serially transmitted to the receiver.
Q:  Can more amounts of data be fed?
A:  No, more amounts of data about attendance cannot be fed.
Q:  Which microcontroller is used in this project?
A:  An 8051 family 40 pin microcontroller is used in this project.
