To my knowledge the information presented represents the current status quo.
The BÜPF's rule is to assist the police in criminal investigations. Assuming a
user has used the Wifi-installation and further assume that user has committed
a serious crime the police has to investigate, then the Cafe owner could be
asked to assist by providing information. However the simple MAC address would
not help here because it would only mean that _someone_ has signed up to the
Café, not that this person has committed the crime or has anything to do with
it. For that the MAC to IP address matching would have to be stored.
Furthermore if you don't store any data on the user itself, it wont lead
If the Cafe owner is considered a telecommunications operator, then he could be
forced to tolerate wiretapping in such a case (assuming the criminal comes to
that Café regularly to commit his crime) but I have my severe doubts that this
might ever be relevant. Firstly because the wiretapping could occur one level
up by the Café's ISP, secondly, because a Café owner is not really a
telecommunications provider etc. The people from the BÜPF are not stupid
neither. They know the real world out there and they know the limitations. So
they don't go for impossible solutions just because the law could imagine them.
So for the Café owner I think its much more relevant to take care of the
Datenschutzgesetz properly by _NOT_ storing anything. Then he should be on the
safe side. The likelyhood he ever will hear from the BÜPF again is very very
