They have to regenerate it every day or so anyway. (The QR code in the article expires after 48 hours.) A not small number of those 115k people per week are elders without a smartphone or no digital abilities except video calling their children and nephews. Luckily it seems that in my country we'll be able to get a permanent QR code (paper or plastic, don't know.) I'm thinking about getting that one instead of the digital certificate: one less app, no worries about batteries and if it worked for my passport, id card and driver license it will be OK for my covid pass too.
