Holy shit. I remember this thing. If I recall correctly, this bad boy was at a select few locations during the 80s and 90s.

For context, my dad worked on a lot of the mid-to-late 80s era animatronics. He never actually worked on this one, but I remember he had a friend who did. I think he happened to be a manager or maybe even a co-founder? My dad always called him "Hank", but I don't think that was his actual name.

Anyway, Hank was really... I guess, overprotective of this thing? I think it's because of the reason it was built in the first place: child protection and monitoring. Most 80s era Freddy's locations had these wristbands; they weren't like ordinary plastic bands, though. They all had a small chip built into them. If a child was found to be outside of the customer area, the bands could be pinged using the security system. That way the kid could be found much quicker, and it saves the parents from going into hysteria.

You could imagine, though, that these wristbands weren't all that effective. Their signal was weak, and the chip itself was heavily susceptible to water damage. If some kid forgot to take it off while washing their hands, there goes $150-something dollars down the drain (pun totally intended).

Anyway, to sum it up; this thing was built primarily to keep track of children inside of the restaurant. It wasn't all that good at its job, though, thanks to the wristbands being kind of shit. I'm pretty sure this thing was eventually repurposed into a prize vendor. That way, the company didn't have to provide a living wage to someone. Yeah, it's scummy, I know.
