Abstract
A document printing system may include a print engine, a controller and a communication port. The communication port can read a portable memory device, which stores an electronic secure file for authorizing the print engine. The portable memory device may store data such as the creation date for the electronic secure file. The portable memory may also store the device identification code and/or the vendor identification code. The electronic secure file may also store the creation date for the file itself, and the device identification code, the vendor identification code, or a balance amount. The system may authorize a print engine by comparing the data in the electronic secure file and data stored on the portable memory device. If the comparison of data finds a mismatch, the system may determine that the print engine is not authorized; or determine that the service is authorized if otherwise.
