By default, Mastercard and Maestro cards are linked to the Cirrus network, but very often all three logotypes of the Mastercard family, Mastercard, Maestro and Cirrus, will be shown. Canadian, American, Venezuelan, Chilean and Saudi Arabian ATMs use this network alongside their local networks and many banks have adopted Cirrus as their international interbank network alongside either a local network, the rival Visa PLUS ATM network, or both. In locations such as India and Bangladesh, the Cirrus network also serves as a local interbank network as well as an international network
