This requires some blue-sky thinking, but as RFID tags become smaller and smaller they will eventually reach the size of a nanoparticle and will subsequently become airborne, thus covering vast amounts of land and objects, including people. With this in mind these connected devices will sense every part of the environment around us and transmit their data in real time to form part of an intelligent system or Smart Grid, that can support and co-ordinate numerous tasks, to ensure they flow efficiently and enhance every day life.
