-Direct bank payments use your bank id. You can have bank id stored in the phone, but you can also use a personal keychain authenticator
-Klarna, Collector, etc use your social security number as the primary identification method
-Mobile payments like Swish and mobile pay use your mobile number, so it is linked to your phone subscription, not your phone.
Of course you still need to have a bank account, but there are a lot of banks out there.
So no batterie, money ? No network, no money ? Phone stolen, no money ? Phone broken, no money ?
What if I don't want to have a spying hardware on me at all time ?
I don't think that is essentially a bad thing. Forcing a digital signature for every transaction makes criminal activity difficult. Modern AML works much better because there is always a digital fingerprint for every transaction.
But I think that these are two distinct issues? Some crypto -things could somewhere in the future solve the privacy issue... But no society wants that, because real privacy makes criminal activity and money laundering possible. But that has nothing to do with credit card duopoly?
But the matter here is card vs phone. Your card do spy on you, but it doesn't have your contact, a microphone, the history of where you have been, etc.
You can easily give your card away to a friend for the day. Your card doesn't need an update. It's not connected to internet all the time. It won't die if it falls, if it rains or of it's too hot. You can have a replacement easily as well.
It's also way more accessible. My grandma can use it. A blind man can. They all work the same way.
A phone is only a good card alternative when every thing goes right. But I value resilience in my paiement system.
