Skinny on German touch transmission

What sounds a lot like the Microsoft skin patent, as well as the same tech tested by NTT Docomo,
a German startup, Ident Technology, is touting Skinplex for human skin as transmission medium. While we thought Microsoft was pushing the envelope, Ident Technology says (in that overly aggressive German-way), "Ident Technology already has the key patents in hand." Skinplex operates at 195 kHk, a license-free frequency, and can be used for authorization requirements, like unlocking car doors, anti-theft devices or protecting portable electronics. The user wears an identifier on his/her body and then touches a receiver which is connected to say the car door. Ident is looking to compete with the RFID market since they say Skinplex will be more convenient and less expensive.
