One or more embodiments of the invention provide a method, apparatus, and article of manufacture for limiting unauthorized access to digital services. The tag unit comprises of transmitting unit and a banding material coupled to the transmitting unit. The imprinting fabric continues to support the imprinted web downstream of the hot press at least up to the final drying section. To help facilitate condensation of the steampigment mixture sent to the condenser, a portion of the condensed slurry is in yet a further refinement pumped from the slurry storage tank to a heat exchanger. This makes it possible to provide data optimal for both display and reuse. In use, an update to data is identified.
