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 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 an initial user interface state corresponding to a user interface state of the other client device.

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: In general, this disclosure describes techniques for unlocking certain functionality of a mobile computing device upon wirelessly detecting that an external device is in relatively close proximity to the mobile computing device. One example method comprises: providing a phone application and a second, different application; initiating a first mode of operation when the mobile computing device becomes locked; prohibiting user access to the second application during the first mode of operation when the mobile computing device fails to wirelessly detect a presence of an external device; and initiating a second mode of operation when the mobile computing device wirelessly detects the presence of the external device and when the mobile computing device has received user input specifying an access password, wherein the mobile computing device allows complete user access to both the phone application and the second application during the second mode of operation.
