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.

Abstract: A merchant terminal or a customer terminal receives first input(s) associated with a first POS transaction with a first customer. Based on the first input(s), it is determined that the first POS transaction is in a first item-input portion and so the merchant terminal is designated as a state control terminal for the first POS transaction. Based on a trigger event occurring for the first POS transaction, it is determined that the first POS transaction is in a payment-input portion, and the customer terminal is designated as the state control terminal. Second input(s) associated with a second POS transaction with a second customer are received prior to receiving payment input to the first POS transaction and while the customer terminal is the state control terminal for the first POS transaction. Based on the second input(s), it is determined that that the second POS transaction is in a second-transaction item-input portion.

Abstract: A point of sale system includes a merchant terminal and a customer terminal. The merchant terminal is configured to display a user interface (UI) window on the merchant terminal. The UI window on the merchant terminal displays a merchant-specific version of a screen displayed on the customer terminal. The merchant terminal receives updates from the customer terminal regarding the status of the payment portion for a transaction. The merchant terminal can provide an input to the UI window which is sent as a message to the customer terminal. Control of state for the point of sale system is shared such that when the system is in a first state, the merchant terminal is the state control terminal, and when the point of sale system is in a second state, the customer terminal is the state control terminal and has control of state for the system.

Abstract: Methods, systems, and computer program products for a digital wallet for a group of people. A group of customers may gather for an event, e.g., a party, in which each person in the group may purchase goods or services on behalf of the group from a merchant. A customer device executing a digital wallet application program acts like a wallet for the entire group. The customer device creates group tab. The customer device associates images of each person in the group to the group tab, and submits information on the group, including the images, to a merchant device operated by the merchant. The merchant device opens the group tab for managing purchases related to the group. At the end of the event, upon receiving an input to close the tab, the customer device can receive a single bill including a total amount, and divide the total amount among people in the group.
