ABSTRACT:
In accordance with the present invention, a consumer communicates a request for purchase of goods and services to a merchant, the goods and/or services being selected from these listed together with their price quotes on the merchant's computer or website connected to a network, such as the Internet. The merchant then communicates a request for a token and an update key to the clearing server, the token being previously purchased by the consumer and residing on a clearing server device. The update key is used as an authorization to modify the value of the token, i.e., to decrement and to increment. The merchant forwards the purchased merchandise to the consumer. When consumer discontinues making purchases at the selected merchant, the merchant returns the updated token to the clearing server. A new key is necessary to make the next purchase. This is the case even where the requesting merchant is the same as that from whom the last purchase was made. When the token is requested, if the token was used after its initial purchase, the present value of the token is made certain by receipt on the clearing server of informational downloads from the merchants.
