Abstract: An interchange computer system includes a billing computer relationship that has a plurality of reference billing computer identifiers and a plurality of reference sensory representations, wherein each reference sensory representation is associated with a respective reference billing computer identifier. A billing identifier receiver receives, from a payment portal computer system, a billing identifier representing a user. A billing identifier transmission module transmits the billing identifier to a plurality of remote billing computer systems at the respective reference billing computer identifiers. A response receiving module receives a positive response from one or more of the billing computer systems. A sensory representation selection module determines select sensory representations for presentation and confirmation by a user at a user computer system connected to the payment portal computer system.
