Radio Frequency Identification (RFID) uses radio waves to communicate between two objects: a reader and a tag. RFID communication is the same as two way radio communication in the sense that information is transmitted or received via a radio wave at a specific frequency.

Passive tags collect energy from a nearby RFID reader's interrogating radio waves. Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader. 

Emerging RFID applications include:

• Self-checkins at Libraries / rental services as well as retail premises.

• Livestock Management and pet identification.

• Toll/road – collection/charging and control measures. Many more RFID-based payment collection systems.

• Building Security - secure access controls, documentation and passports.

• Airports - for baggage tracking and tracing/locating.

• SMART home controls - systems to manage home/business energy consumption/production.

• Seismic Sensing - such as locating gas lines and temperature sensing (geophysical).

• Environmental - Energy, Ozone & Pollution measuring equipment.
