Abstract: Methods and systems coordinate an Internet-based financial transaction between an Internet merchant and a customer. A first information packet is received with a payment network from the Internet merchant. The first information packet has a credential assigned to the customer and transaction information specifying at least a cost of the Internet-based financial transaction. With the payment network, account information is determined that identifies a financial account maintained by the customer at a financial institution and authorization information that allows debit access to the identified financial account. A second information packet that includes the transaction information, the account information, and the authorization information is generated with the payment network.
