> I again called the credit card company and this time, told them to cancel all the digital wallets (there were 99 of them!). There is no way to do this online.

This is highly dependent on your bank. For example, Bank of America lets you view and delete any cards that have been added to a digital wallet right on their website.

Only digital wallets, or also any merchant that saved the card using a token? The latter is getting more and more common, but usually happens transparently to the cardholder.

Theoretically, it would allow a pretty neat feature of being able to manage all merchants that have a copy of the card in the banking app and revoke said copies – but since token use is not mandatory, that would be fairly confusing, so I haven't seen this yet as far as I remember.

FWIW, India has taken a pretty radical step towards that future at a regulatory level by effectively mandating merchants to no longer store the underlying card number and use tokens instead. I suspect that such an interface would be more common there, but I don't have any personal experience.

Half of my cards can't even be added to non-iPhone devices without a verification phone call to some poor support agent who's never heard of a "Pixel Watch", has no idea what the workflow is on his end to manually verify cards being added, and just wants me to "use the iPhone app to verify".

Heaven forbid if I try to add a card to an Apple Wallet on a Mac where no iOS or Android app exists.
