RFID technology is one of the leading enabling technologies in building the Internet of Things (IoT), since inanimate objects in daily life will join the network via this technology. For this reason, this chapter provides an overview on RFID applications and ongoing research issues based on the current literature, scientific papers and commercial applications. It provides basic concepts that include the main definitions required in order to understand this technology.
The following section provides the basic definitions relating to RFID technology. Chapter 2 of this book provided deeper knowledge related to this technology.
5.2.1. Radio-frequency identification
RFID stands for radio-frequency identification and is used mainly for tracking and tracing objects, animals and people. Its major advantage over its predecessor, the barcode, is that the identification is stored electronically and can be retrieved wirelessly via an interrogator or reader with no line of sight required.
The basic hardware through which this technology is implemented is built upon three elements: transponders or tags with or without inbuilt energy that stores an identifier (ID) related to a specific object, readers or interrogators that obtain the ID stored in the tags and servers to perform the processing of collected data following a certain application. This is also called RFID middleware.
