Any resources on RFID system design

Dear All,
I am going to do a project on RFID system and I actually don't have much idea on how to design it, can anyone suggest some good web site that contains the technical information on how to design. Thanks for any advice.

I don't think you cn design a whole RFID system which is just too large for just one or few persons to do. However, you could try to design a small part or block of it with limited resource available. For example, you could design the antenna for tags or the antenna for the readers. You can also try to design the receiver and transmiitter for the reader. To start with, you can download the specification of a particular RFID standard, study it, decide which block to design and start the design.

Thanks, then can you suggest some links to find those RFID specifications?

Also you can search for Chips or readers.
