The removable cartridge comprises a signature scanning unit for use in generating a signature based upon an intrinsic characteristic of an article. By providing a signature scanning unit in a replaceable cartridge, few or no modifications to the existing desings ov various reprographics devices are needed. Additionally, the installation of the signature scanning unit in a reprographics device is made as easy as replacing a standard removable cartridge, such as, for example, an inkjet or toner cartirdge. The addition of authorisation/identification functionality to various conventional reprographics devices can also be made by a non-technical user using various embodiments of the invention.</p> |
