How would I go about doing this with an RFID system?

John,

It would depend on the material from which your walls were made. Gypsum board and many other materials will not block RF signals from a passive UHF reader, so you could read through such walls with little problem. If the walls were made of metal or were extremely dense, however, it would be a good deal more challenging to read through them. You could try batter-assisted passive (BAP) tags.
