Abstract: An on-line payment system comprises a computer system which can maintain accounts in a database for a plurality of users. The system is enrolled as a payee in a bill payment system so that users can transfer funds from their bank accounts to electronic cash accounts in the system by making a bill payment to the system. The bill payment is deposited in a bank account maintained by the operator of the system. The system includes a double-entry, net zero accounting system which ensures that electronic cash in the accounts on the system is supported by actual cash on deposit in the bank account of the system. Users can spend electronic cash before the system actually receives funds via the bill payment system. Electronic cash spent during this period is marked uncleared by the system. The system includes reconciliation software which matches payments received to uncleared electronic cash and marks the electronic cash as being cleared.
