Hi Sandeep,
Actually I haven't got that far...
However as I planed it, I don't want involve the user too much-
just to keep simple. I plan to build a safe box, and people throw
personal things into it. That's all.
I want to use it with Android devices. Will complex implementation
build barrier for ebedded system?
Any suggestions?
Regards
Freeman Zhang
