Abstract: Techniques for providing friction-free transactions using geolocation and user identifiers are described herein. These techniques may ascertain a user's location based on a location of a mobile device. A transaction between the user and a merchant may be completed with zero or minimal input from the user based on the geolocation of the mobile device and the user identifiers. In some implementations, a transaction initiated earlier is completed when the mobile device arrives at the merchant. Additionally, a parent-child or similar relationship may be established between multiple devices. Security on the mobile device based may be provided by biometric identification and calculation of variance from regular movement patterns. Advertisements may be sent to the mobile device based on bids from merchants near to the mobile device. Promotions may be sent to the mobile device when more than a threshold number of mobile devices are located at the same merchant.

Abstract: A comparative sizing method in which at least one well-fitting source item is received having at least one source item property associated therewith and a target item having at least one associated target item property for which a resultant comparative sizing recommendation is being requested based on the at least one source item as specified by its at least one source item property associated therewith. Each source item and the target item is correlated with each database item having associated database item properties in a database based on source-database item matches and target database item matches. The resultant comparative sizing recommendation is determined based on the correlated source-database item matches and target-database item matches.
