He principle of the IoT refers to everyday objects and people being uniquely identifiable, trackable and inventoried with the ability to communicate with each other over a unifying network; the internet. A core facet of the IoT concept is Radio-frequency Identification (RFID), which is used to identify and track the ‘things’. RFID are intelligent barcodes which can speak to a network system through electronic RFID readers (Bonsor & Fenlon, 2007). This allows RFID to track how objects move through space and to record this information into a network system (Bonsor & Fenlon, 2007). A key advantage of using RFID is that they do not necessarily need to be in direct contact with the reader. Modern RFID technology was first developed in 1973 and has become more efficient and smaller in size over the past 40 years (Violino, 2003).
