Hello Everyone.im looking to do my final year project on automatic class attendance system using RFID.I have gone through lot of details regarding the project but still there are lot of things which i dont understand.Here are few:
1.Which RFID reader is most sutible for this Project?
I think the operating frequency sutiable for this project is 13.5 Mhz but i dont know which reader gives optimum performance with minimum cost.
2.Once the reader is selected,How to connect it?..either via RS 232 or USB and why?
3.I have read somewhere that a microntroller is required as well..but i dont get my around that why do we need it?..why cant we trasnmit the data directly to PC via RS232.
once these doubts are clear,i can start this project.i have 3 months to complete this project. these are the modules.
Readiung RFID tags with reader
Interfacing to PC.
Creating a database
Sending the data wirelessly to University administration..
it will be a great help if anyone of u clear my doubts and gives me more detail regarding the project and how to do it efficiently.thanks
