I just returned from Zurich[1] which involved, of course, two pair of International entry/exit. While I was there, I availed myself of rapid antigen testing and my proof of vaccination with the canton of Zurich to attend several jazz shows and concerts (!) unmasked and with no covid restrictions. I used QR codes throughout. QR codes printed on paper, QR codes on a website that I pulled up in my phones browser, and once I even used a picture of a QR code in my photoreel that I pinch-zoomed into and properly scanned.[2] It appears that there is no use for, nor appetite for, covid vaccine passport apps. This makes me very happy because I have envisioned, through the entire pandemic, some perfect storm of pairing a smartphone to yourself, as an individual, and tying identification to it and being forced to register the phone and the app and yourself and the SIM card ... and what a mess that would end up being. Instead, it appears we are all just going to produce QR codes in whatever way works best for us and if the scanner beeps and turns green, nobody cares what else is going on.

Once that was cleared up, she zoomed in on the QR code and scanned. Easy.
