In one aspect, a computing apparatus includes: a transaction handler to process transactions; a data warehouse to store transaction data recording the transactions processed at the transaction handler; and a portal to receive a request from a client device over a network, the request including user data identifying at least one user. The client device has activity data recording activities of the user, and has the capability to determine from the activity data a first value for a first propensity score of the user. The computing apparatus further includes a score evaluator coupled to the data warehouse and the portal to determine a second value for the first propensity score based on transaction data recording payment transactions of the at least one user identified by the user data. The portal is configured to provide information based on the second value in response to the request.
