Does reader detect tags around certain area of coil only? This is vital bcz i want it should detect tags of those students present in the class or sitting on benches at that instant.Bcz i want that rfid attendance should work behind the curtains ,i mean students shouldn't have to take any extra efforts to make attendance by coming in vicinity of reader,b'cz it will consume time and may create lil chaos in class.

well that is understandable but the thing is.. it create chances of false attendance in our language we call it proxy i hope you are getting my point.

Its better to proceed with project idea instead of looking for modification in project idea..

for students, little effort is not a big deal they are not so old yet hehe..

Well your suggestion is good and practical too,but i want to reduce the time required to take attendance during each lecture.
...That means there is not any way to block proxies while using high freq reder,isn't it?

it takes not more than a second to mark successful attendance. I thnk just concentrate on your project implementation, later on you can find ways to add more advancements in it. that will be good i think.
