    Over time, various drivers affecting information technology architecture design have been proposed which favored either more centralization or decentralization. With the advent of RFID and other sensor technologies, the next inflection point heading towards decentralization might arise. This paper aims to improve the understanding of the decentralization debate by investigating the factors that influence the design decision on whether or not to store data on an RFID transponder label. By analyzing eight case examples from the manufacturing domain, the following main factors could be identified: synchronization, external data exchange, security, standardization, flexibility, and response time. A detailed discussion of these factors may be helpful to companies planning to implement RFID applications on how to design their systems.

    The EPCglobal Network, an emerging standard for RFID, aims to raise visibility in supply chains by enabling interested parties to query item-level data. To arrive at that end, a critical piece is yet missing: a Discovery Service to identify possibly unknown supply chain actors holding relevant data for specific EPC numbers of individual products. However, the Discovery Service architecture as initially conceived by the EPCglobal needs revision as it either infringes the confidentiality of participating companies or its use is limited to identify only participants already known. This paper has two main contributions. Firstly, we discuss the limitations of the architecture under consideration by EPCglobal and present an alternative, more adequate Discovery Service design. Our concept encourages participation in the network while ensuring information provider confidentiality. Secondly, we present a roadmap for extending the existing EPCglobal Network with two critical services: an automated contract negotiation service and a billing service.
