help money clip

I have found that there are some places where you don't feel safe, and when you are around a threatening situation you can't really call the police. I came up with this idea so you can notify the police without drawing attention. I chose a money clip because it is something anyone can have and it is low profile. my idea for this is to have a Bluetooth module that connects to your phone so whenever you press the button it sends a notification to the police or any emergency contact you have set up. this is still a working progress, I still have to design an app that texts the police a message of your choice. this will use the location from your phone to tell the police where you are. I hope you all like this idea, I would like to make a working prototype of this one day, but I think I have to make some changes to the cad before I can do any such thing.
