An interbank network, also known as an ATM consortium or ATM network, is a computer network that enables ATM cards issued by a financial institution that is a member of the network to be used to perform ATM transactions through ATMs that belong to another member of the network.
However, the functions which may be performed at the network ATM vary. For example, special services, such as the purchase of mobile phone airtime, may be available to own-bank but not to network ATM cardholders. Furthermore, the network ATM owner may charge a fee for use of network cards (in addition to any fees imposed by the own-bank).
Interbank networks enable ATM cardholders to have access to ATMs of other banks that are members of the network when their own bank's ATM is unavailable. This is especially convenient for travelers traveling abroad, where multinational interbank networks, like Plus or Cirrus, are widely available.

These started to consolidate from the mid 1980s resulting in three major interbank networks by 2003 that had over 70% of the volume in the United States:
