This kind of thing goes all the way back to "beaming" between Palm Pilots, in 1998.[1]
Apple added "knocking", which they called called NameDrop, a few years ago. You bang two phones together and the simultaneous acceleration tells them to talk over NFC.
But apparently Apple has gradually been locking down that feature because it's used to help organize protests.[2] Can't have that.
