Temporarily provisioning functionality to a personal device in a multi-device point-of-sale (POS) system is described. In an example, a presence of a personal device operated by, or on behalf of, a merchant can be determined to be within a range of a POS system of a merchant. The POS system can include a merchant-facing device and a customer-facing device that is coupled to the merchant-facing device. Functionality can be provisioned to the personal device that (i) configures the personal device to present a merchant user interface (UI) via a display of the personal device to enable the merchant to interact with one or more customers and (ii) enables the personal device to interact with at least one of the merchant-facing device or the customer-facing device. Responsive to determining an occurrence of an event, the functionality can be de-provisioned from the personal device.
