RFID technology functions through a two-way wireless transmission between tags and readers. The communication between the tags and the readers rely on the use of waves known as radio frequency waves or RF waves. There are two types of RFID systems available: passive and active. The passive RFID systems possess readers that merely emit a signal, which triggers a current in its corresponding tag and enables the tag’s transmitter. Active RFID systems lack the presence of a reading device since the tags broadcasts its presence on its own.
