A small section of society enjoys dressing up in “interesting ways” that generally involves latex, corsets, rubber and other novel clothing items only available at select stores in certain parts of San Francisco.
Some even “enjoy” wearing the modern day equivalent of a chastity belt or other restrictive device.
So why not make the chastity belt, or whatever happens to be your bondage item of choice, RFID controlled?
The belt could contains a detector scanning for a correct signal from a matching RFID “key.”
The belt remains unlocked only when in proximity to this “key.”
A sort of digital leash.
Now you could be boring and wear the key on a key chain, but hey, everyone is getting RFID implants these days, so just stick the RFID key beneath the skin in your hand or your genitalia and you’re good to go.
The strange things I think about when drunk on a Christmas day.
