Abstract: System for conducting a financial transaction with a single financial presentation device linked to multiple financial accounts stores financial account information of multiple financial accounts associated with the presentation device, and a set of predetermined rules for determining which of the financial accounts is to be used to conduct a financial transaction. A linked-account processing program receives an authorization request for the financial transaction which has been initiated at a merchant's computer using the presentation device. The program determines whether the presentation device is associated with multiple financial accounts, and if so, selects one account among the multiple linked financial accounts based on the predetermined set of rules, and routes the authorization request to an issuer of the selected financial account.
