On: Detect breaches with Canary credit cards

[vlabakje90]

Revolut has single use credit cards as part of their offering. You can either choose to create a new one for each transaction (disposable card) or a virtual credit card that you can use more than once but discard if something happens to it.

Because both types are virtual prepaid type cards, some services (e.g. car rental) will not accept such cards.

(Transfer)wise offers virtuals too, though not prepaid

For a more traditional banking, Estonia's LHV allows (seemingly) unlimited free virtual cards.

Capped to 3 virtuals, though.
