This part of ISO 24534 provides requirements for electronic registration identification (ERI) that are based on an identifier assigned to a vehicle (e.g. for recognition by national authorities), suitable to be used for: - electronic identification of local and foreign vehicles by national authorities; - vehicle manufacturing, in-life maintenance and end-of-life identification (vehicle life cycle management); - adaptation of vehicle data (e.g. for international resales); - safety-related purposes; - crime reduction; - commercial services. It adheres to privacy and data protection regulations. This part of ISO 24534 provides an overview of the ERI system concept, in terms of the onboard vehicle components and the external off-vehicle components required for an operational system. The detailed requirements are defined in Parts 2, 3, 4 and 5 of ISO 24534 and more limited, though relevant, provisions are defined in ISO 24535.
