Ephemeral Card

For a private user, just like the functionality that allows you to generate e-mail aliases, it could be extremely interesting to be able to create virtual payment cards (Lydia, Revolut, N26 etc.).
That way, everything would be ephemeral and disposable.

Just to add additional examples and resources for this request; 1Password has a similar integration with a well known service called Privacy for these “virtual cards”.

Though if I recall correctly Privacy only works with US banks and cards, not sure how that is handled with other password manager integrations.
