RFID in Tabletop Games

Radio Frequency Identification (RFID) technology already plays a major role in many areas. In business applications, for example, the idea of smart shelves or tables equipped with RFID technology has been around for some time now, especially for retailing. Current solutions, however, are designed to only identify objects in range, which is sufficient for most of the envisioned shop applications. For other uses, however, not only the identification, but also the exact position and orientation of objects would be interesting, if not necessary. A good example are miniature war games, where the current game state usually depends on what objects are located where, and, in some cases, how these objects are oriented.
