Re: I still don't understand
I understand that -- I'm not saying there's zero benefit. I'm just not seeing how the benefit outweighs the drawbacks. Security is a broad topic -- the sort you're talking about is one thing, but there are other aspects that we have to trade off for that. For example, to get that, it appears that we need to expose ourselves to new entities such as Google.
This is a classic cost/benefit calculation, of course, and people's personal calculations may differ. I'm just saying that personally, this doesn't even begin to pencil out in a positive way for me. Unless, of course, I misunderstand and Google (or Apple, or whoever) really can't see what I'm buying and from where, using what card. If the only party to the transaction is the processor who would be handling the card anyway, then I can see the benefit -- but I'm not so sure that's the case.
