ABSTRACT:
A computer-based electronic payment system, in which a payer's check issuing computer issues an electronic check having a check identifier and an issue time, where the check identifier includes a payer identifier for uniquely identifying a payer and a payment identifier for uniquely identifying a payment. Then, at a payee's check processing computer receiving the electronic check from the payer and at a bank's check processing computer receiving the electronic check transmitted from the payee, a check identifier of each electronic check accepted during a prescribed period of time prior to a current time is recorded, and a received electronic check is refused when the issue time of the received electronic check is older than the prescribed period of time past of the current time or the check identifier of the received electronic check is identical to any recorded check identifier of an already accepted electronic check, or a received electronic check is accepted when the acceptance is not refused.
