I love virtual cards. I use privacy.com for all my online stuff. Not a solution for this purpose unfortunately.
As for your divide-it-up approach, that’s an interesting thought. I guess I’m a little concerned about signing up for several cards with several companies and several privacy policies. Feels a little weird to me, but I do see the merit in not having all your eggs in one basket.
As far as the Apple Card and Goldman Sachs is concerned, I’m still trying to figure out which details are given to whom. Its hard to find info about it. I wouldn’t be surprised if you’re right and it’s the same as any other card from Goldman Sachs.
Interesting idea. How easy is it to start and LLC?
