Techniques associated with a multi-functionality customer-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. The customer-facing device is capable of operating in a first state or a second state. In at least one example, the customer-facing device can present a graphical user interface (GUI) on a display. The customer-facing device can transition from the first state to the second state. The second state can enable the customer-facing device to perform at least one additional functionality that is not available to the customer-facing device in the first state. The customer-facing device can receive, while in the second state, an input via the GUI and can send to the merchant-facing device, an indication of the input.
