Abstract: An online payment card is a digital form card derived from a credit/debit card or bank account of a customer. A central service provider issues the online payment card electronically to a registered merchant system under the authorization of the owner of the ordinary credhVdebit or bank account. The central service provider maintains the association of the online payment card with the ordinary credit/debit card or bank account of the customer, and the identity of the merchant that the payment is issued to. The merchant handles the online payment card in the same manner as ordinary card. When the merchant submits a request for authorization, the central service provider verifies if the online payment card is associated with the merchant who submits the authorization request. If the verification successes, the central service provider process the authorization request using the ordinary credit/debit which is associated with the online payment card.
