Issuer (or Issuing bank)

A bank that issued a card for a shopper to make cashless payments via an ecommerce website, inside a mobile app, or in a physical store. To be able to issue a card, an issuer must be a member of one or several card networks, or subscribe to one of the card services (for instance, ICS).

Sometimes a shopper's bank is referred to as an issuer even if there is no card issued. This is to distinguish between a shopper's bank, which sends funds, and a merchant's bank, which acquires funds.
