I think a more apt description would be proxy cards. It’s relatively new, but it lets you create cards that are linked to your primary without ever issuing a plastic card. This way if fraud happens you only need to replace it for the services it was used on. Or if you happen to lose your physical card, you can have it replaced without affecting the others.
Do you mean tap-to-pay, or do you mean card numbers you can use for online purchases?

I think this is the same thing as when I said
I admittedly didn’t describe it very well, though.
