RFID technology is one of the key building blocks for the IoT.66 It is a technology used to uniquely, accurately and automatically identify, track and locate assets through wireless radio waves (as opposed to optical barcodes).67 RFID systems are composed of two components: (i) a transponder (RFID tag), which is attached to a “thing” (which can be practically anything, from a computing device to a grocery product, even an animal or a human being68) and serves as a data carrier, and (ii) a reader or registration device,which reads the data of the transponder.69 From a security perspective,RFID is a highly vulnerable component, as no higher level of intelligence can be enabled on it.70 A popular industry proposal for the infrastructure of the IoT is based on an Electronic Product Code (EPC). 71 In such an infrastructure, ‘things’ are objects that carry RFID tags with a unique EPC. 72 The infrastructure can offer and query EPC Information Services (EPCIS), both locally and remotely to and from subscribers. 73 Instead of saving the information on a RFID tag, distributed servers on the Internet can supply the information through linking and cross-linking with the help of an Object Naming Service (ONS).74
