What could be a good product(not in market) that'll make use of a (RFID) radio frequency identification tag?
or even doors. i would welcome all ideas.
I haven't seen it on the market, so I built it myself:
All family members have a RFID tag. Anyone leaving or entering through either the main door or the garage will be counted. If the result is "zero", then -
- the heating system is lowered by 3 degrees
- all unnecessary (non-security) lights are turned off
- all doors are electrically bolted shut
- alarm system is made "hot"
The process reverses if the count result is >0
microwaves and microwave dinners, that way you don't have to do anything!
