The developed traceability graph enables tracing of information associated with products and their parts. Tracing in a supply chain requires the three integrated levels of actions: 1 at the physical level the Radio-Frequency Identification (RFID) is used for physical objects; 2 at the data-storing level logical counterparts of RFID tags and database objects are mapped; 3 operational actions determine how recourses, emissions etc. are portioned in different parts of the traceability graph. Briefly, we integrate RFID technology with databases and operational actions of the supply chain. Using RFID for tracing cumulated resources and emissions in supply chain

The lack of a unified RFID standard and the diversity of available technologies make it difficult to safeguard privacy without being to identify potential threats in advance. To address this problem, we present a threat evaluation system intended to enhance privacy in RFID. Our proposed model allows users to customise services based on their evaluations of potential threats. Furthermore, prospective users may refer to previous user feedback to evaluate the reliability of different service providers and to aid in the selection of suitable commercially-available services.

Using a museum as an example, we develop a 3D virtual navigation system that supports indoor RFID localisation. If a user is carrying a notebook or mobile device while walking through an exhibition room, the system can update the user's position accurately. This information can be used to guide users as they near particular historical objects; for example, the system can trigger special information that alerts users and helps them experience real and virtual historical relics, buildings, and incidents more completely.

When multiple tags transmit their IDs to the reader simultaneously, collisions occur and the performance of tag identification degrades. In this paper, we propose a probabilistic counter-based anti-collision protocol using the idea of Parallel Splitting (PS) to reduce tag collisions. The proposed protocol also utilizes an adaptive identification-tree height adjustment mechanism to fine tune the effect of PS.

According to the timing specification in this standard, a conforming interrogator (or reader) shall complete the inventory round for tags in a soft real time. This research develops a software-defined radio reconfigurable FPGA-based interrogator for the standard to address the stringent time constraints of the tag-reader handshakes. This flexible interrogator is fully customisable and can be utilised for typical applications including standard conformance test automation and large-scale programming for tag groups. Furthermore, on-chip signal processing allows for real-time online collision resolution in a tag-intensive environment and can significantly improve the system reading efficiency.
