I suppose switching back to a card wouldn’t be a total disaster, but it wouldn’t improve privacy unfortunately. My banks debit cards use vpay anyway (and as far as I know all of them use either vpay or maestro) so US companies will know about all our payments either way…

Does e-os support mobile payments yet?

A Big-tech free phone os sounds really appealing, but for me, a lack of mobile payment would be a reason to seriously consider sticking with ios when my current phone needs replacement.
