Interbank network

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.

Interbank networks also permit, through different means, the use of ATM cards at a point of sale through the use of a special EFTPOS terminal where ATM cards are treated as debit cards.

United States
Due to the historically fragmented nature of banking in the United States, there have been a large number of small banks, which resulted in a number of different interbank networks being established, mostly along geographic lines. These started to consolidate from the mid 1980s, resulting in three major interbank networks which, by 2003, had over 70% of the volume in the United States:
 STAR
 NYCE
 Pulse

2003 saw the founding of two additional interbank ATM networks:

 Allpoint 
 MoneyPass
