Radio frequency identification technology has received an increasing amount of attention in the past few years as an important emerging technology. However, the intrinsically passive features of existing RFID systems, to which the authors refer as first-generation RFID systems, render their adaptation to real-world dynamics in order to efficiently comply with up-to-date application specific requirements difficult. To address this challenging issue, they propose an evolution to second-generation RFID systems characterized by the introduction of encoded rules that are dynamically stored in RFID tags. This novel approach facilitates the systems' operation to perform actions on demand for different objects in different situations, and enables improved scalability.
