The VOD purchasing method enables a user-viewer to purchase goods via a shop OD (on-demand) process on an interactive TV (STB enabled TV). The user selects shop OD goods and the STB-TV creates a transaction ID code with the STB-ID code or the cable head end (HE) or shop OD client application at the HE creates the trans-ID. The trans-ID is displayed on the user's TV. If created at the HE, the trans-ID is sent as metadata or configured VA to the STB-TV. Supplemental communications channels may deliver carry trans-ID to the user (cell phone, VoIP, land-line telephone, Internet or fax). User profile data is gathered via supple-comm channel lists purchasing limits (time, day, monetary, and PIN). The shop OD computer server limits purchases thereby. Financial fraud and abuse parameters are set at the OD server as are parental control parameters.
