Good luck if you are intending to build one as per the said parameters. But If you intend to buy a ready assembled tested RFID secured access system, you may have a look at www.united77.com/projects.htm...They have 125 Khz module with interfacing to 89S52, with magnetic door sensor, LCD and keyboard with 2 on board relays. One for lock and other for siren. The project comes with complete description, schematics, Sample codes, Block diagram and the kit.
Cheers

i appreciate your reply, mostly projects are built by using AVR but the concept is same.

after trying a lot to build one, loosing a lot of time, ... FAILED to build one with no BUG!
If your looking into passive cards then I suggest to use per-modules like em4095 or rfr300 ...
If you want to build one your self then you have to have a LOT OF PATIENCE!
