To promote an object maintained by a social networking system, an advertiser identifies the object to the social networking system. Based on the user interaction with one or more posts associated with the object, the social networking system selects one or more candidate posts from the one or more posts. Promotion efficacies of each candidate post for a group of users having one or more common demographic characteristics are determined and a candidate post is selected based at least in part on the promotion efficacies. The selected candidate post may be identified to the advertiser or presented to additional users having the common demographic characteristic by the social networking system.

Identifying posts in a social networking system for presentation to one or more user demographic groups

Systems and methods for near-field communications with a mobile device are disclosed. In one embodiment, a computer-implemented method for near-field communication may comprise: detecting, by a source device located at a point-of-sale, the proximity of a receiving device; encoding purchase data on an audio signal with one or more ultrasonic frequencies; and transmitting the encoded purchase data to the receiving device, wherein the encoded purchase data is transmitted using a speaker of the source device.

Ultrasonic near-field communication

Several embodiments include a social network system that generates an implicit social graph connection between a first social network object and a second social network object. The implicit social graph connection can be generated based on a shared profile attribute between the social network objects or a user interaction in the social network system. The social network system can store the implicit social graph connection in a social graph of the social network system. The social network system can provide a social network service that selectively presents, based on the implicit social graph connection, a content entry to a client of the social network system.

Implicit social graph connections

One variation of a method for calculating advertisement effectiveness includes: posting an advertisement for a product to a social feed within a social networking system; tracking a view of the advertisement by a user; determining a proximity of the user to a store of a merchant; in accordance with a privacy setting of the user, selecting personal data of the user from data stored in the social networking system, the personal data including an identity of the user and an interest of the user; in response to the determined proximity of the user to the store, transmitting the selected personal data to the store; and, in response to a transaction between the user and the store, assessing an effectiveness of the advertisement according to a determined correlation between the transaction and the view of the advertisement by the user.

Methods for calculating advertisement effectiveness

A method of operation of a transaction collection system includes: initializing a sniff daemon on the POS terminal; determining a sales transaction on the POS terminal; recording a transaction document of the sales transaction on a memory of the POS terminal; collecting the transaction document from the memory with the sniff daemon; and providing the transaction document for interpretation on an external system.

Transaction data capture system for a point of sale system

A method includes: determining a first user interaction on a social network system; identifying a social network object in the social network system associated with the first user interaction by traversing a social graph of the social network system; identifying a user account based on the first user interaction; generating an implicit social graph connection between the user account and the social network object; and selecting a content entry for displaying to a user device signed-in under the user account or a friend account based on the implicit social graph connection, the friend account socially connected to the user account via the social graph of the social network system.
