Abstract: One or more embodiments of the disclosure include an electronic communication system that applies a content enhancement to a digital content item and sends an electronic communication containing an enhanced digital content item. Specifically, the electronic communication system can detect enhancement selection information related to the electronic communication and, based on the enhancement selection information, suggest one or more context specific content enhancements. For example, the electronic communication system can analyze enhancement selection information related to features of a digital content item, characteristics of a user, information from a social graph, and/or other information to suggest one or more content enhancements to the digital content item, apply the one or more content enhancements to the digital content item, and send an enhanced digital content item to a recipient in an electronic communication.

Abstract: In one embodiment, a method includes receiving a first notification through a real-time push service. The first notification includes a subset of user-facing information of an object having one or more states, the subset being determined at a first point in time. A second notification is received through the real-time push service. The second notification is an update to the user-facing information of the object, and the update may be a subset of user-facing information determined at a second point in time after the first point in time.

Abstract: In one embodiment, a method includes sending to a mobile client computing device a first notification through a real-time push service, the first notification including content and being associated with a stateful object; the method also includes, in response to a state change of the stateful object, sending to the mobile client computing device a second notification through the real-time push service, the second notification including an update to the content based on the state change of the stateful object.

Abstract: In particular embodiments, a method includes receiving a message in response to detection of a token by a presence reader; transmitting a request to access an account associated with an external network in response to receiving the message; establishing access to the account in response to authentication of the request by a server in the external network; and debiting value from a funding source associated with the account after establishing access to the account.

Abstract: In particular embodiments, a gaming kiosk may be granted federated access to social networking information of a user, initiated upon activation of a physical access token. A user may initiate a workflow, by activating a physical token, that establishes a federated access session between a gaming kiosk and a social networking system to allow the gaming kiosk to augment the user's experience with social networking information and to publish gaming information to the social networking system.
