Might you mean: "Badges? We ain't got no badges."  ?

as said by Gold Hat, played by Alfonso Bedoya, in the John and Walter
Huston/Bogart 1948 film _The Treasure of the Sierra Madre_ ?

With RFID, we'd know whether he _did_ actually have one, wouldn't we ? ;-)

According to someone who apparently keeps track of such things in the
HomeSeer forum on the CheapRFID, there were 600 posts and ~16,000 reads on
the topic since November 2006 (!).

Open-field range with $4 antenna is about 300 feet (up to 750 feet
reported) for the "40 meter" device and somewhat less for the "8 meter"
version.
