An enhanced automated teller machine (ATM), system and method for securely authenticating and enabling a financial transaction at the ATM. The method includes receiving at a central computer system, planned transaction data representing a future financial transaction. The central computer system generates first and second verification information, sends electronic data including the first verification information to the ATM, and sends electronic data including the second verification information to a user device. The central computer system receives multiple sets of electronic data from a user device and multiple sets of electronic data from the ATM. Multiple comparisons of certain sets of the electronic data from the ATM to certain sets of the electronic data from the user device are conducted at the central computer system. If the comparisons result in positive verifications, the central computer system sends electronic data including instructions for the ATM to execute the planned financial transaction.
