||The market penetration on the part of mobile devices (e.g. mobile phones, personal digital assistants, etc.) supporting wireless communication and interaction opens high-potential application areas in our everyday lives.

It aims at bringing together people who are in physical proximity, in equal or similar situations or do have the same interests.
