Abstract: A user interface of an automated teller machine receives a first input that identifies a transaction type. Next, a near field communication reader of the ATM detects a first near field communication message from a first mobile device so that the automated teller machine can extract a first account identification information from that message. The first account identification information comprises data related to a first account associated with a first user. A second NFC message from a second mobile device associated with a second user is detected in order to extract a second account identification information from the second NFC message. The second account identification information comprises data related to a second account associated with the second user. Once the ATM has the needed information, it can initiate a transaction based on the transaction type, the first account identification information, and the second account identification information.
