Bookkeeping perspectives on a correspondent relationship. From Bank A's view: a Nostro account is Bank A's account at Bank B ("our account with you"). A Vostro account is Bank B's account at Bank A ("your account with us"). The same account, viewed from each side, has different names.
Technical service provider handling the technical authorisation and clearing of card-payment transactions. Distinct from the acquirer (who holds the merchant relationship and licence).
