Yes...I had the public library on my police beat back in the early 80's and the RF theft detection systems were already well established back then. I'd get lots of calls about people stealing books and have to go over and process them. I had to learn about the detection system in order to explain it to the D.A. and sometimes a judge/jury. It always amazed me that the little wire grids were not powered.
It wasn't true RFID (emphasis on the ID) but more of RF detection. The antenna would simply activate a sensor when the item was passed through a detection system, a simple go-no go technology. Of course, I was just speculating when I suggested that "design" might be an RF grid...could be part of a circuit or something totally different, but that was my initial impression.
I know...the cops are all replicants and that's the guy's thumbprint (they put thumbprints on real police ID's).

Yea...the Disco Detectives ... :cool
On the name, my guess would be IBM Selectric Typewriter Courier 10 or 12 ball. Do the card blank, type in the name (if anyone still has a typewriter).
Did they have RFID tags in 1981? I thought those were in use only starting a couple years ago. Even that foil thing they put in DVD cases only started maybe 10 years ago.

Yeah the rounded letters on the "real" prop makes it look way too casual and informal. The whole thing in fact looks kind of "mod" and not "official" at all.
It's an ID card for "swingin' seventies" cops. :lol
