Abstract: Methods and systems are provided for enrolling a customer with a payment network. Customer-identification information identifying the customer, financial-account information identifying a financial account to be used in supporting transactions over the payment network, and presentation-instrument information identifying a presentation instrument currently incapable of supporting a transaction with the financial account are received at a host system. A customer account associated with the customer-identification information is established with the host system. With the host system, the financial-account information and the presentation-instrument information are linked with the customer account to permit the customer thereafter to execute transactions supported by the financial account with the payment instrument.

Abstract: Methods and systems are provided for processing a transaction between a first party and a second party. Information defining terms of the transaction and identifying a presentation instrument are received at a host system. Preference information associated with the presentation instrument is retrieved with the host system. The preference information specifies terms for an allocation of transaction amounts among multiple transaction types. An amount for the transaction is allocated among the transaction types in accordance with terms of the transaction and the terms for the allocation.
