Abstract: A first client device or system performs a method that includes retaining in memory registration information for a respective application indicating the respective application is registered for sharing application state with other client devices or systems. The method further includes storing an application state of a respective application, and detecting a transfer triggering condition. The transfer triggering condition includes presence of a second client device or system within a predefined proximity of the first client device or system, and the predefined proximity is a predefined proximity for near field communication. Furthermore, upon detecting the triggering condition, the first client device or system determines, in accordance with the stored registration information, that the respective application is registered for application state sharing, and transmits the application state of the respective application to the second client device or system.

Abstract: A computer-implemented technique includes initiating, at a first computing device including one or more processors, communication with a second computing device via a short-range wireless communication protocol. The technique includes receiving, at the first computing device, a set of information from the second computing device via the short-range wireless communication protocol, the set of information for configuring communication via a different, second wireless communication protocol.

Abstract: An application service system receives, from a merchant service system, an application program code comprising identifying information. The identifying information is extracted and the application is distributed for operation on a user device. A user interacts with the application, creating an access request that is transmitted to the application service system along with the extracted identifying information. The application service system transmits an access token to the user device comprising the received identifying information. The user device transmits the access token with a service request to the application service system. The application service system compares the identifying information from the access token to the identifying information extracted from the application program code received from the merchant services system. If the identifying information matches, the service request is processed.

Abstract: A method can include receiving, at a first computing device having one or more processors, a command to transfer a data payload to a second computing device and information from the second computing device using a near-field communication (NFC) protocol. The information can be indicative of a plurality of communication protocols capable of being received at the second computing device, including the NFC communication protocol. Additionally, the method can include estimating a transfer time corresponding to each of the plurality of communication protocols. Each of the transfer times can be indicative of an amount of time to transfer the data payload between the first and second computing devices using its corresponding communication protocol. The method can also include selecting a specific communication protocol based on the estimated transfer times and transmitting the data payload using the specific communication protocol.

Abstract: A computer-implemented method includes determining, at a first mobile device associated with a first user, whether a second mobile device is within range for near field communication (NFC). When in range, the method includes receiving, at the first mobile device, first data and second data from the second mobile device via an NFC transmission, the first data being based on input from a second user associated with the second mobile device, the second data being metadata indicating a software application configured to process the first data. When the first mobile device does not have the software application indicated by the second data, the method includes retrieving, at the first mobile device, the software application via a network. The method also includes providing, at the first mobile device, the first data to the first user via the software application.

Abstract: Systems and methods are described herein for enabling users to select from available secure service providers (each having a Trusted Service Manager (“TSM”)) for provisioning applications and services on a secure element installed on a device of the user. The device includes a service provider selector (“SPS”) module that provides a user interface for selecting the secure service provider. In one embodiment, the SPS communicates with a key escrow service that maintains cryptographic keys for the secure element and distributes the keys to the user selected secure service provider. The key escrow service also revokes the keys from deselected secure service providers. In another embodiment, the SPS communicates with a central TSM that provisions applications and service on behalf of the user selected secure service provider. The central TSM serves as a proxy between the secure service providers and the secure element.

Abstract: A first client device performs a handoff operation to a second client device by transmitting application information, associated with a first application, to the second client device when the first client device is positioned within a predefined proximity of the second client device. The first application has a first client device user interface state when the handoff operation is performed. Further, the first client device, in response to receiving from another client device application information associated with a second application executed by the other first client device, executes a third application corresponding to the second application with a user interface state corresponding to a user interface state of the other client device.

Abstract: A first client device executes a plurality of actively running applications, each having one or more checkpoints, each checkpoint identifying an execution breakpoint at which a respective application can be suspended and subsequently resumed. The first client device detects a transfer triggering condition, stores an application state for each of the plurality of actively running applications, and transmits the stored application state for each of the plurality of actively running applications to a second client device or system. The stored application state for each respective application of the plurality of actively running applications corresponds to a checkpoint of the respective application. Optionally, the transfer triggering condition includes presence of the second client device or system within a predefined proximity of the first client device or system, wherein the predefined proximity is a predefined proximity for near field communication.
