Startup Idea : intelligent handbag for ladies

We all know ladies' handbag can be a mess but they can't go out without it. The idea is to create a device to track the presence of things that are supposed to be in your bag. Each element is connected to your smartphone app that lists what is actually in your bag and what is not. You spent the night at a party at a friend's place and it's time to leave, check your app and be sure that you have your keys to go back home.
