Techniques associated with a dual state merchant-facing device are described herein. A point-of-sale system can comprise multiple devices, such as a customer-facing device and a merchant-facing device that is coupled to the customer-facing device and can operate in a first state or a second state. In at least one example, the merchant-facing device operating in the first state can present a graphical user interface (GUI) on a display. The merchant-facing device can transition from the first state to the second state, the second state enabling the merchant-facing device to perform at least one additional functionality that is not available to the merchant-facing device in the first state, and can update the GUI based at least in part on the at least one additional functionality.
