I'm talking about a keychain that is directly connected to one's mobile via bluetooth technology. And at time when the wireless connection between the mobile and the keychain is broken, the mobile alarms.
The keychain should work anywhere in between 2 to 25 meters of distance. Also, a slide or push kind of button could be used in keychain to switch off the bluetooth connection when one don’t need it.
Surely, It will help those who usually leave their keys behind -- for example:- When someone forgets to pull-out key from his car/bike/scooter and walk away, then after a certain distance the mobile of the person will alarm to alert him that he has forgotten his key behind.
