IM-messenger / drone service concept


In this concept, IM-messenger can bring small and important things over like wallets, documents and so on. So that people do not need to go back to get that things. Sometimes when people go out, they not notified or remembered that something will be used so they don't bring it. At that moment IM-messenger can bring it over for them.
