- have a security system with tamper-resistant assets (example a safe crypto processor, secure file system, human-readable features) and is able of provided that security services (example privacy of information in the memory).
- Benefit managed by way of a essential administration system which interchanges information and design settings with the card throughout the security system. The later includes card hot listing, updates for application data.
- Card data is transferred to the essential administration system via card reading devices, for example ticket readers, ATMs etc.
