7. Smart Metering
• Real-time or near-time registration usage
• Remote and local meter reading
• Remote services activation/deactivation
• Tamper-detection
• Data-storage
• Advanced tariffs

9. Mobile display?
• Everyone has a mobile/smart/PDA?
• Reusing existing devices infrastructure
• Handheld device as a “swiss-knife”
• Advanced hardware and software platform
• No additional deployment requirements
• Costs / Fun
