The reviewed RFID technology for IoT Healthcare and the personal experience of the authors tell a story of mixed opportunities and fragmentation. Worldwide university laboratories
are now researching and making prototypes of RFID sensors, both passive and semi-active that can be interrogated from a distance compatible with the interaction with a network infrastructure.
On the other side, only few products are commercially available for large-scale applications. A very focused effort is, therefore, needed to manage the conversion from experiments to the real use and mass production within a so potentially fast growing market. The overcoming of the slowing factors
demands a coordinated activity of the IoT community to stimulate interest in potential final users and, in parallel, to boost the evolution of readers, software, and devices toward a more interconnected perspective.
