RFID Based Attendance System Using Raspberry Pi
Controlling unit is in the institute. Whenever the card is placed near the reader, it will take the attendance. This article explains the same. Data is transferred from RFID cards to reader and from there to microcontroller. Radio frequency technology is used in many applications.
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.

Great work you've done sir, am not an engineering student but how can i verify that the student is present or not please help sir.
Hello good afternoon, I am trying to make these methods work with a PIC, I have the connections and some routines already done, however I would like to make the following query. The sensor has a limited memory, I want to save the templates in a database, I understand that the process is to take the image "readImage", convert it "convertImage", create a template "createTemplate", then load the saved template again " loadTemplate "and then send that template, or am I wrong?
How can I send this template? Should it be done with "downloadCharacteristics"? According to the code that you show with " Searching. Reply 7 months ago. Reply 1 year ago. Hii'm in an engineering school and working on this project without RFID and buttons and have a lot of issues on it, can we contact ourselves in order to realize it? I have just a few questions about the db connection. Thank's a lot. By ledatjhi Follow. About: Newbie frankydachi gmail.

Right here we've got taken four RFID tags wherein three are used for college kids and 1 is used for invalid card. First Of all I have install wiringPi Library for raspberry pi in my raspberry pi.
By using giving commands:. Here i have used very familiar language to write code that is embedded c.A few years ago, when Radio Frequency Identification RFID electronics was still at their adolescence stages, the time stamping technique was greatly followed. As software programming and technology progressed, especially in electronics, they gave way to a much secure and reliable arrangement known as RFID Attendance System.
Most of the educational institutions still utilize the traditional paper method to mark attendance. This is both paper and time-consuming. By utilizing RFID Systems into the daily activities of students, data can be well organized and recorded.
The RFID method has enormous benefits. With it maintaining daily attendance on Excel sheets could be avoided, labor can be reduced, the monthly attendance record of staff and students can be assembled in a single place and format.
RFID is being used actively in retail, healthcare and other sectors to monitor workers. Since the workers in these sectors are large in number, hard to handle and their work can be performed by others in case of absenteeism; there the attendance mechanism is of trivial significance. RFID card based time attendance system was an abstract concept that craved path to biometric fingerprint systems. The latter is a topic of discussion for another day; this article elaborated on how the former can be implemented in educational institutions to monitor and track students, teachers and staff whereabouts, their absenteeism, and regularity.
The card serves as an identity mark of an individual and contains essential identification data of a person. Every individual is issued a card with a different unique code. This is a wireless system that can be integrated with SMS notification too. EduSys cloud-based Enterprise Resource Planning ERP Software is programmed with 21 st century codes to take-in and track attendance, data sheet in any formats.
Attendance Management is one of the many modules in the application. From managing staff data to tracking school buses, everything and anything can be performed online simply on EduSys. Note: The cost of the Card is excluded from the cost of the system.
All Rights Reserved. Powered by. Toggle navigation. There are many methods to track attendance of an individual. The System is expensive because a lot of technology goes into making it In case of a large strength of students, purchasing tags for everyone is costly Replacing microchip, radio transceiver, antenna and battery in the system tiresome and costs money Since it is not as secure as biometric, the system is prone to manipulation Advantages of RFID for Attendance Tracking RFID card based time attendance system was an abstract concept that craved path to biometric fingerprint systems.
The System provides more accurate identification Quick and Rapid: Identifies candidates in seconds The System is less tedious, cost-efficient, easy to use, hard to adulterate and modest Educational institutions like schools, colleges and universities can precisely screen regularity of students, teacher and working staff and counteract proxy marking and error RFID Machine: Card and Reader A rectangular Plastic Card, sometimes called Tag, and Reader devices are part and parcel of the RFID machine.
How to Choose the Right System? Request a Demo and Buy Online.An RFID based Attendance System is a very interesting project which can be used in different places say in Schools to register the attendance of students and teachers, Private organizations to tabulate monthly working hours of employees and automatically calculate salary based on the number of hours registered in the office and other similar kinds of applications.
The choice of a microcontroller or a development board is purely based on the additional features and functionality you plan to incorporate into the system. Such a kind of system which communicates with the internet can be designed efficienlty and easily using AVR Atmega series controllers.
If you are designing for hobby purpose, such a system can be easily designed using Arduino. When the same person swipes his RFID tag again, the system will save it as his leaving time and add it to his total working hours. Button 1,2,3,4 are used for selecting the menu and different options within the menu. This will eliminate the use of of external pull up resistors by enabling the internal pull ups of Arduino. Our system uses a 20 x 4 LCD module for displaying purpose. Download the Arduino Program.
LiquidCrystal is for interfacing LCD module. The address of the I2C device is mentioned on the beginning of the program. There are both 7- and 8-bit versions of I2C addresses. These are followed by two functions that convert decimal numbers to BCD binary-coded decimal and vice versa. The function setTime is used to set the clock. Using it is very simple to insert the values from year down to second, and the RTC will start from that time.
Reading the time from your RTC IC is just as simple, in fac, the process can be followed neatly inside the function displayTime. Two pointer arrays are declared at the beginning which contains the RFID codes and names of the persons.
The name and ID code of every staff should be enrolled in this array on the programming time. The controller will compare the received ID with the previously stored codes in the above mentioned array. A flag is then host inside the program to point out the presence of that person. The working hours is then calculated using the arrival and leaving time.
