Develop a bluetooth hardware
I am willing to develop a keychain with a bluetooth enabled in it. So that it can be connect to mobile phones and on loss of connection a alarm is generated reminding the person of his belongings. This shall help people who forget their keys in cars or cafe table frequently.
I am having trouble in developing the hardware. Can anyone help me regarding it. 
 Thanks!!
