So, because of radical transparency of how the mechanism works, everybody can verify that is only going to the site that they actually trust and if you don’t trust any of the telecommunication carriers, you can use the Taipei city municipal government’s app scanner. So, there are the six telecom and if you don’t trust any of the six players, you can still stamp or write your way in if you trust the venue more than you trust the telecom but at the end of the day, it will all go back to the same contact tracing system so it allows you to elect which federated party to trust the most. And you don’t have to trust anyone else then. The venue, if you scan the QR code, learns nothing about your phone number. Your phone company doesn’t learn anything about how those 15 digits map to the venue.
