Citi and Capital One have done this for a decade now

MBNA (acquired by bank of america) was doing this in 2001 [0]

I think Apple's credit card does something close to this:

Citi has done a terrible thing to their offering. Years ago, you could set the total value and its expiration date for a virtual card number. Nowadays you can set only the _daily_ maximum. Which makes them useless.

One Finance (via an FDIC-insured partner bank) offers a physical debit card, a "virtual" card behind that, and the option to create "pockets" that you fill with money, and you can generate additional "virtual cards" or account numbers for each pocket to enable transactions directly from the pockets.

Been really satisfied with the product since Simple died. https://www.one.app/

My citi double cash card has it.

Citibank and Capital One offer them on some cards, iirc

Bank of America used to offer these after acquiring MBNA, but stopped a few years ago in favor of better fraud protections.

CapitalOne, it’s specific to certain credit cards they offer. Bank of America used to, unsure if they still do.

Capital One makes you download a browser extension for some reason which I refuse to do. There is no other way to use them, not online not in the app. It's the craziest thing I've seen.

Erste Bank have it too. At least for Debit cards
