There is a turn-key, long range RFID using Wavetrend hardware

http://www.wavetrend.net/pdfs/L-RX201-04%20Reader%20PI.pd

developed and market for home automation by iAutomate that does what you
are looking for. Interface software is available for Crestron and Homeseer
home automation systems.

The principal drawback is price, especially if you want more than one
location (reader). Cost for a minimal setup is about US$700.

Homeseer RFID discussion board is here:

As with many Homeseer plugins, there are "issues".

I've looked for less expensive options, including home-brew DIY and found
none. Eventually they will emerge. Wavetrend (what iAutomate uses)
themselves have less expensive readers. Keep us posted on what you learn.
