What is Mastercard?

Mastercard is the card payment network: it authorises and routes a payment between the merchant and the bank that issued your card, so the issuer sets the terms rather than the network. Several cards here run on it. Aqua Card lists a contactless Mastercard, Avant includes Mastercard zero liability protection, and AVO Bank runs on the Mastercard payment system with an interest-free purchase period. BAM combines Mastercard perks with cashback of 1-2.5% + Mastercard perks. Axo Group pairs the same network with boosted cashback at a booking site and on Zalando gift cards.
