IIRC this is how the Apple Watch's feature that unlocks your Mac works. It's not vulnerable to repeaters and only works within ~3 feet of the watch and the Mac.

I’ve found the range for unlocking your phone with the watch is even tighter. When I’m on the subway it’s less than six inches, presumably because of local radio noise.

Yep. The reference I saw actually says ~3 meters, but even in seemingly ideal conditions, I don't see it reliably work except within probably just one.
