A recent episode of Law & Order: SVU included an RFID subplot; basically, a geeky character established as a bit of a tinkerer with the technology (he’d set up keyless entry on his house) turned out to have surreptitiously implanted a chip in his wife’s shoulder to ascertain whether or not she was having an affair (she was).
When the arrangement came to light, Detective Stabler referred to it as a “HoJack.”
We like this more than we can say.
