There is no anonymization of the Customer data before it is read by the conductor. The QR code just contains a link to your digital profile at SBB, and they then check your status online. (Perhaps they have a database of all valid GAs on the cellphone, because I got also checked in the tunnel, where I had no reception).

Otherwise there is only the promise that they will store the data anonymised and if you write them, that you don't like your data to be sold to other companies, they won't do it.

Not a lot that you can do here. As everything is now through. The good part is that the Half fare isn't checked very often digitally. (Put this could change when it's one year past since the swisspass was introduced) I myself was very surprised that there was not more outcry over the obvious privacy problems with the SwissPass.

Hi all, I've been struggling to find accurate information about the SwissPass RFID cards. Is there just a lack of information in English or has there been no debate about this issue at all? Does anybody else know anything about how the "anonymization" of customer data works? Is it just a gimmick or is it based on some open algorithm that can be trusted? I came across a couple of links that don't really give any details but they suggest the SBB can't be trusted: http://lenews.ch/2015/09/04/does-the-swisspass-protect-your-personal-data-questions-are-asked/ https://www.reddit.com/r/Switzerland/comments/3hjwg8/can_i_change_my_swisspass_back_to_a_ga/ Regards, Daniel _______________________________________________ Zurich mailing list Zurich@lists.fsfe.org https://lists.fsfe.org/mailman/listinfo/zurich
