Ankle Monitor

Electronic tagging is a form of surveillance that uses an electronic device affixed to a person. In some jurisdictions, an electronic tag fitted above the ankle is used for people as part of their bail or probation conditions. It is also used in healthcare settings and in immigration contexts. Electronic tagging can be used in combination with the global positioning system (GPS), but for short-range monitoring of a person that wears an electronic tag, radio frequency technology is used.
