Techniques for conducting transaction(s) between a merchant and customer(s) via a. multi-device point-of-sale system are described. The multi-device POS system can include a merchant-facing device having a first processor for processing first instructions for presenting a merchant user interface (UI) on a display of the merchant-facing device. Further, the multi-device POS system can include a first customer-facing device having a second processor for processing second instructions for presenting a first customer UI. The first customer UI can enable a first customer to perform a first action associated with a first transaction. The first customer-facing device can have been coupled to the merchant-facing device at a first time. Further, the multi-device POS system can include an application, which can be stored on the merchant-facing device, a second customer-facing device, or a personal device, for presenting a second customer UI enabling performance of a second action.
