Payment

Paying with a passkey is a different problem from logging in with one: the transaction has to be bound to what the user saw. This series covers Secure Payment Confirmation and dynamic linking, how EMV 3DS accommodates FIDO, the passkey services the card schemes now run, and the integration models available to a merchant or PSP.
