A transponder is a simply an electronic device created for sending and receiving electrical signals. The word "transponder" is a cross between the words transmitter and responder. Although mostly used in military and air commute applications, transponders are used by the average consumer as well. Instances of transponders can be found in cell phones, radar detectors, GPS systems and more.
Decryptor
Transponder decryptors allow you to identify and clone transponders by emulating their functionality with wireless signals. They are capable of interfacing with computers, detecting transponder activity and generating codes to communicate with transponder devices. Decryptors are often made for a specific brand of transponder or type of encryption, but generic ones are available, and the device's functionality can be extended with a personal computer.
RFID Programmer
Many transponders identify and track radio frequency identification (RFID) chips. These small devices have a miniature antenna and are capable of storing small amounts of data. RFID chips can be made to work with a larger transponder as part of a security access or tracking system, but they will need to be programmed using an RFID programming device. These small devices write to the data store of an RFID chip similar to how a magnetic card writer writes to a card's data track.
Antenna Couplers
Transponders and the devices that communicate with them have antennas attached in order to interpret the radio signals sent or received. Antenna couplers allow an array of different antennas to be linked together on a single device. Each coupled antenna can be tuned to listen on a different frequency or enhance the listening capacity of the device. You can use a coupler both in a transponder or on the device tuned to listen to it.
