Disclosed herein are system, method, and computer program product embodiments a dual-core automated teller machine (ATM). The dual core ATM system and method includes two physical central processing units (“computing devices” or “cores”) that are configured to perform operations in coordination with peripheral devices. Peripheral devices of the dual-core ATM system can include a peripheral screen, such as a touch screen, a card reader, a PIN pad (e.g., an encrypted pin pad or “EPP”), a cash dispenser, and a cash deposit module. A peripheral switch can isolate one of the computing devices from the one or more peripheral devices and that can permit the other of the computing devices to control the one or more peripheral devices. By maintaining redundant hardware sets within the ATM enclosure, the system can avoid a necessary reboot or powering-off in the event of, for example, a software failure.
