Cities across the world are about to enter the next phase of their development. A near invisible network of radio frequency identification tags (RFID) is being deployed on almost every type of consumer item. These tiny, traceable chips, which can be scanned wirelessly, are being produced in their billions and are capable of being connected to the internet in an instant. This so-called ‘Ambient intelligence’ promises to createa global network of physical objects every bit as pervasive and ubiquitous as the worldwide web itself. Some are already calling this controversial network the ‘internet of things’, describing it as either the ultimate convenience in supply-chain management, or the ultimate tool in our future surveillance.
