Abstract: A method of delivering goods or services via an encoded medium to a holder includes generating data in a database associated with a central computing station in response to an assignee of the medium and a provider of goods or services separately communicatively linking the medium to a central computing station. The data generated in the database includes the identity of the assignee, the identity of the goods or services associated with the medium, and the identity of the goods or services provided by the provider. A value of the medium is established, wherein the medium assumes different values based on various conditions. After the provider of goods or services provides the goods or services to the holder, the value of the medium is updated and recorded in the database.

Abstract: A new method of dispensing, tracking and managing pharmaceutical product samples by communicatively linking prescribers and pharmacies to a central computing station. The present invention entails utilizing product trial media that is exchanged for actual pharmaceutical product. The media is encoded with information that identifies a particular pharmaceutical trial product, such as by magnetic encoding similar to that used with credit cards. The media is distributed to participating medical doctors or prescribers who then activate the media via the central computing station. The prescriber then transfers the activated media to patients who then present the media to participating pharmacies. Before filling the pharmaceutical trial product identified by the media, the pharmacy validates the media via a link with the central computing station.
