Essentially, Radio Frequency Identification (RFID) systems collect information about physical objects automatically. Because information about tagged objects can be transmitted for multiple objects simultaneously through physical barriers and from a distance, RFID has an advantage compared to reading barcodes that require ‘line-of-sight’ and active user interaction to access the enclosed information. RFID systems exist of three main parts: (1) the tag, which is the identification device attached to the object being tracked, (2) the reader that recognises the presence of a tag and reads and processes the information which is stored on the tag and (3) the antenna, which is part of the communication between tag and reader.
