Siri, Where are my keys?
Somebody please solve this. I will throw all of my money at you. That is all :)
- JoachimSchipper 15y agoThere are already solutions, e.g. http://startingline.en.alibaba.com/product/502176603-212131584/personal_alarm_device_Credit_Card_RFID_key_finder_beep_alarm.html http://startingline.en.alibaba.com/product/502176603-2121315.... I'm sure you can find more, RFID seems a rather obvious technology for this kind of thing.
