The ‘Embedded Based Attendance System’ as name implies used to take attendance by electronics means.
The attendance system usually takes on attendance register or paper. That is transfer/fed to digital database or master book. By this method paper is wasted as it is a limited natural resource. Instead of these two steps: intended system is designed to carry out in simpler form.
Take the attendance on embedded system and transfer it to PC for master database updates. No need of paper, reused for many times and its portability makes use anywhere. This system is less time consuming as compared to manual paper based attendance system.
But this system needs RFID tags at each attendance end, one RF reader at registering end.
Objective: Taking attendance of the RFID tag holder.
When a user swipes his RFID tag, system checks its Number on its memory resident database, if found displays ‘Authenticated’ message and registers the attendance. If swiped RFID tag number not found ‘Unauthorized’ message is displayed on LCD screen.
By pressing reset button, attendance process will be stopped and attendance entry will be displayed on LCD screen.
Again pressing the reset button, the attendance process begins freshly.
Learning curve:
The system is built around ATmega8 Microcontroller. The code does all the controlling part of the system.
On-chip peripheral UART of ATmega8 Microcontroller is used to read RFID Reader.
Note that in reviewing project back up of data to Master PC is not implemented. User can easily implement that feature also by referring other such sources.
Applications:
- Such system/project is implemented in educational institutions, industries, warehouses, etc.
The system does not address two situations: Person carrying an RFID tag is attendee or not; and error in the attendance register due to malfunction of the system.
