Thanks, that makes sense. A QR code came up I was supposed to show to the "next" person as I entered, and out of habit I tried to screenshot it in case it disappeared, my phone said I could not scan the QR code for security reasons - so that might be why they use that App. Still, I'm deleting the GooglePay/Wallet now after all that - if I wanted Google Pay on my phone it would already be there. I'm not terribly phone security conscious, but it seems silly to have a Payment App permanently installed that does nothing except give me (what should be free) Lounge access lol.
