From Product RFID-Data to Product Services Product is Vanishing towards the Services it supports !!! Ö Product abstraction i.e. Product Disappearing in everyday life e.g. Clock is a common object in our day-to-day environment Ö It is everywhere but we no more see it but instead the hour (i.e. service) it provides Intelligent product

Principle of On-Product Service Based Relationship SUPPLY CHAIN ACTORS
RFID Tagged Product as a service provider or a service requester, demanding transparent and associated control mechanisms of all the offered services in its environment. RESULT
The service represents a material and/or an information resource that offers a specific functionality (actuating, sensing, computation), which can be locally available, or remotely invoked through a network.
DISCOVERY
Ambient Network IP - WiFi - Ethernet CONTROL (ACTION)
Ambient service is an abstract view of a system that provides information management capabilities, processing capabilities and event messages in an ambient network, representing a working domain.

PRODUCT 4
Ambient Service Architecture Generic Standard Features • Identification: To know the product unique identity in the ambient network. • Localization: To know where the product is situated in the ambient network. • Information brokering: To identify the information sources allowing the execution of a given service • Service Discovery and Registry: To automatically discover and advertise for services in the ambient network. Each new service provider is broadcasted at the time of its connection to the network • Service Invocation: Process by which a service execution is requested by a client • Event notification: To notify about change in the services variables. Users must first subscribe to event notifications mechanism.

Conclusions • Product is a Communicating Object acting as a Services Provider / Requester • Open Ambient Architectures and RFID are needed to deploy products interactions With light-weight implementation, No proprietary OS
• As a UPnP entity, the product assumes intelligent interactions in an IP ambient network • Services Classes definition according to Product Life Cycle Activities • Concerning the introduction of Advance RFID concepts in industries, a case was presented. This industrial application highlights the need to develop emulation and control simulation systems to achieve the Supply Chain global indicators EU RFID Forum - March 13/14th 2007 Brussels
