A transponder (short for trans mitter-res ponder [1] and sometimes abbreviated to XPDR, [2] XPNDR, [3] TPDR [4] or TP [5]) is an electronic device that produces a response when it receives a radio-frequency interrogation. Aircraft have transponders to assist in identifying them on air traffic control radar. Collision avoidance systems have been ...
An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number , back to the reader.
A traffic alert and collision avoidance system ( TCAS, pronounced / tiːkæs /; TEE-kas ), is an aircraft collision avoidance system designed to reduce the incidence of mid-air collision (MAC) between aircraft. It monitors the airspace around an aircraft for other aircraft equipped with a corresponding active transponder, independent of air ...
Traffic information service – broadcast. Traffic information service – broadcast ( TIS–B) is an aviation information service that allows pilots to see aircraft that are not emitting ADS-B data but have a basic transponder . As aircraft are discovered by primary radar and respond with encoded altitude information, this information is ...
Electronic toll collection. E-ZPass tollbooths, like this one on the Pennsylvania Turnpike in Bensalem Township, Pennsylvania, use transponders to bill motorists. Electronic toll collection ( ETC) is a wireless system to automatically collect the usage fee or toll charged to vehicles using toll roads, HOV lanes, toll bridges, and toll tunnels. [1]

Three types of transponders are available: transponder sticker (free version), E-ZPass (hard case) transponder and E-ZPass bumper-mounted transponder. Personal (limited to five transponders/vehicles) and business accounts (unlimited) are available; a $1 fee is imposed per month if the account has been inactive for 12 months.
