This application demonstrates a prototype attendance system using RFID and a software developed in C# .Net framework. The software interacts with the RFID reader through the serial port. The software has very limited functionalities. However it can be extended to a complex commercial application. The aim of this project is to show how RFID module can be interfaced with the PC directly without using a microcontroller.
The hardware needed is an RFID reader and a cross connection serial cable. The RFID reader used here has an onboard MAX 232 and hence can be directly connected to the PC. There is no need of microcontroller in between.
This application works for two RFID tags i.e., for a maximum of two people. It is assumed that there are two people carrying ID card with RFID tags pasted on them. The unique ID is known and stored in the software.
When the software starts, we can enter the name of the two students corresponding to the tags in the Tag 1 and Tag 2 text box. Now press the start button to start the application. This will connect the software with the RFID reader through serial port using inbuilt .Net libraries.
Now when the first student swaps the card (RFID Tag) in front of the reader, his name along with date and time stamp will appear in the right side display box. Similar thing will happen every time any of the cards will be swapped and the date and time data will get stored.
In case you want to terminate the connection with the RFID reader press the stop button.
This is a very simple example to store the attendance with the time and date stamp. This can be extended to n number of members with many additional functionalities.
