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.

Transaction interface control

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.

A computer-implemented method for coordinating documents between computer systems includes identifying, on a computing device, changes made by a user to a document having a model stored on the computing device, with corresponding models stored on a remote client and a server system; generating from the identified changes, one or more mutations that describe the changes and a one or more locations that correspond to positions in the model where the changes are to be provided; receiving one or more mutations from the server system and transforming the generated mutations using the received mutations; and updating the model stored on the computing device using the transformed mutations.

A technique for a proxy card to emulate each of a plurality of payment cards according to emulation rules associated with the payment card. The proxy card initially selects one of the plurality of payment cards for emulation based on one or more selection rules or a user instruction. Next, the proxy card emulates the selected payment card according to one or more emulation rule associated with the selected payment card, each relating to how emulation is performed with respect to time, location, business, or other factors.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for processing payment events. One of the systems includes one or more processing engines configured to periodically retrieve information from a payment event feed that comprises a list of payment events in an order, and a server configured to perform a sequence of steps for a payment transaction, the sequence of steps including receiving a request for authorization of the payment transaction from a merchant, receiving an indication that the payment transaction has been authorized, and sending authorization to the merchant for the payment transaction without receiving acknowledgment that the one or more transaction processing engines have received the request for authorization, wherein the server is configured to record completion of each step in the sequence of steps as a payment event in the list of payment events to generate the payment event feed.

A first message comprising first information specifying a file is received from a first server. Respective second messages comprising second information specifying the file are transmitted to a plurality of lock services. Assignment information identifying a file server assigned to handle requests related to the specified file is received from each of the plurality of lock services. One or more conflict resolution rules are applied to reconcile conflicts among the assignment information received from the plurality of lock services and to determine an assigned file server assigned to handle requests related to the specified file. A third message identifying the file server assigned to handle requests related to the specified file is transmitted to the first server.
