Abstract: A method may include receiving, from users, information identifying items purchased by the users, the information including a price for each of the items, and storing the information in a database. The method may also include receiving, from a second number of users, additional information identifying items purchased by the second users, the additional information including a price for each of the items, and identifying a first item in the database that matches a second item associated with purchases by one of the second users. The method may further include determining whether the price for the second item is lower than the price for the first item stored in the database and updating the database to include the second price for the first item, in response to determining that the second price is lower than the first price.

Abstract: A system may generate a matrix according to subscriber count data for a plurality of points of interest within a geographical area over a period of time identified from aggregate subscriber data, the matrix including counts per subset of the period of time arranged according to subset of the period of time and point of interest. The system may further perform a factorization of the matrix of subscriber counts to extract feature components of the subscriber count data, identify at least a primary feature component and a secondary feature component according to the factorization, and provide a ranking of at least a subset of the points of interest according to at least one of the primary feature component and the secondary feature component. The system may also receive a request for a report, generate the report according to the identified feature components, and provide the report responsive to a request.

Abstract: A method and apparatus for improved approaches for pairing of a POS system and mobile device is described. The method includes: determining, by a POS system, a proximity of a physical location of a mobile device to an access point associated with the POS system, wherein the mobile device is configured to connect to the access point and to initiate establishment of a communication session over a service provider network; initiating a link, via the access point, between the mobile device and the POS system based on the determined proximity; receiving, via the link, an indication of an item that includes a good, a service, or a combination thereof; determining, by the POS system, item information for the item based on the indication; and transmitting, via the link, the item information to the mobile device.
