Keith,

Key word for you to know is  "Weigand" (the name used for an
industry-standard,  electronic/electronic  security  protocol).

Google on " Wiegand" or "Wiegand rfid home automation"  to get information
on door units that respond to that standardized protocol and rfid.


These devices are often used in commercial situations and tend to be pricey.
 Elk products www.elkproducts.com had an attractively priced I-button add-on
for their Magic Module series, but no RFID last I knew. Used with
appropriate HA software, it can tell you which fob ('who') was used  where
and when. The I-button needs to be within an inch or so, not feet..

HTH ... Marc
