Abstract: In one aspect, a computing apparatus is configured to receive an input specifying a set of users, identify a set of triggers, each of which corresponds to a set of one or more conditions which when satisfied cause transmission of a message to the set of users, rank the triggers based at least in part on transaction data of the users that was recorded by a transaction handler, and generate a ranked list of the triggers based on the ranking.

Abstract: In one aspect, a computing apparatus is configured to: capture first images of customers who have watched a digital sign, using a digital camera attached to the digital sign positioned in vicinity of a retail location; identify characteristics of the customers based on the first images; identify, using the characteristics, a subset of customers who have made payment transactions at the retail location through a transaction handler; determine an aggregated spending profile based on transactions of the subset of customers recorded by the transaction handler; and arrange content on the digital sign based on the aggregated spending profile. The computing apparatus may be further configured to capture second images of the customers who have made payment transactions at the retail location through the transaction handler, using a digital camera attached to a point of sale (POS) station at the retail location, and to correlate the first and second images to identify the subset.

Abstract: In one aspect, a computing apparatus is configured to generate trigger records for a transaction handler to identify authorization requests that satisfy the conditions specified in the trigger records, identify communication preferences of the users associated with the identified authorization requests, and use the communication preferences to target real-time messages at the users in parallel with the transaction handler providing responses to the respective authorization requests.
