Securing audio/visual equipment
This is a very simple concept but I'm amazed that I haven't seen it yet. Why can't we have smart cards for audio and visual home equipment? Why not a smart card activated hi-fi? It won't turn on without the card and won't turn off unless you remove the card... Or what about the removeable fascia that was used for a car stereo? why not have a fascia that operates both your home and car stereo? I prefer the smart card idea though. If you lose it all you have to do is bring your receipt to the store and they can 'chip' a new one for you - maybe it would be linked to the serial number of the equipment? It just seems to me that since so many homes get broken into why can't your stereo or vcr or TV have that extra level of protection that makes them useless if they're stolen?
Reward: Getting the smart-card protected device for free would be reward enough for me.
