When excise tax stamp systems are being planned, rolled out or renewed, thought needs to be given to the longevity and future proofness of the system. This presentation outlines the role of thinking in terms of functional units that make up a system, rather than getting tied up in a silo.

The basic assumptions of ISO 16678:2014 (for interoperable object identification and related authentication systems) and ISO 22381:2018 (for establishing interoperability among object identification systems)
are recaptured in this presentation. In particular, the role of a third-party unique identifier (UID) issuing instance is highlighted in detail.
