Interesting! I have completely ignored tap-to-pay and all sorts of phone wallets precisely because I am unwilling to let the big tech companies control my life. I had never considered that there might be an acceptable way to use this technology.
But this sounds much better and more "fundamental", as in, will support any bank.
I'd commit immediately to the 3 euro/month to get rid of my passes in the magnetic pouch on the back of my GrapheneOS Pixel 10 :)
