hello everybody,

I have an idea, but i don't know IF it could work, or HOW to do it.

this is the idea: to have an application that has two sub-states:
normal state: the smartphone (nokia n9 in my case) is silent and/because is next to an NFC tag.
alarm state: the smartphone makes a hell of a noise and/because is far from the above tag

the trigger from normal to alarm would be a check of the proximity with the tag (every 5 seconds? don't know), and the trigger from alarm to normal would be a password / facelock / voice check / blood exam / whatever.

the reason i thought of this system is simple: in a subway, in a swimming pool (if you leave the smartphone on sight), or wherever, it's more difficult to steal the smartphone AND the NFC tag than the smartphone alone. this is truer when the tag and the phone are in different pockets of the same jacket for example.


when it's about coding, I am THE IGNORANCE in the flesh
i don't even have an NFC tag, so i really have no idea what i'm talking about

but maybe you do
