    Abstract: Techniques and arrangements of a point-of-sale (POS) system including a transaction interface control mechanism configured to prevent simultaneous input by a merchant and a customer during a transaction. The POS system can include a merchant user interface (UI) presented on a merchant-facing display and a customer UI presented on a customer-facing display. In some instances, the merchant UI can be on a display of a merchant device, while the customer UI can be on a display of a customer device. In such instances, the merchant device and the customer device can be operably connected via a wired or wireless connection.
