It does not stand for Automated Teller Machine.
ATM is a network technology based on transferring data in cells or packets of a fixed size. The small, constant cell size allows ATM equipment to transmit computer data over the same network as video or audio data is sent. ATM creates a fixed channel, or route, between two points whenever data transfer begins. This makes it easier to track and bill data usage across an ATM network, but it makes it less adaptable to sudden surges in network traffic.
Customers can make transactions with any bank within the network. They can:
As long as the ATM terminal they are at is in the appropriate network that their bank has an association with. The Union Bank ATM's are capable of transactions through MasterCard®, Visa®, Pulse®, Cirrus®, and Plus® networks.
Keep in mind that non-Union Bank ATM terminals may have a service charge placed on transactions when using those terminals.
