Re: Hmm
Given that Apple Pay doesn't actually send card numbers, and I assume Google Wallet doesn't either...
Not often a problem. Legislators simply create legislation defining the capabilities that must be offered wrt contact tracing, ie ID+location (and watch that scope creep..)
Then it's 'simply' a matter for Apple & Google to comply with that legislation, because it'll be the law. So non-compliance makes it illegal to use those payment methods.
On the plus side, Apple & Google can spaff lots of money at lawyers & lobbyists to challenge laws.. But in the current climate, that'll probably be answered along the lines of "If you have this data, we want it as well!".
