Maybe I’m misunderstanding something, but if the card number is changing after every payment, I wonder where it makes sense to use those cards in the first place.
What I mean is, when shopping online (e.g. Amazon, Apple, Google, you name it), many companies store your CC details to make it easier for you to pay again later. As it would be pretty annoying to change the CC number for every payment, I wonder what the use case is for disposable cards.
Online stores where you buy for the first time and don’t know if you want to trust them? (if so, then why buy there?)
Would the card number change already be triggered by the initial authorisation that most companies perform? I hope not
Can someone enlighten me please?
