RFID
They who can give up essential liberty to obtain safety deserve neither safety nor liberty ~ B. Franklin

Livestock are monitored with Radio Frequency Identification Devices (RFID), as mandated by the U.S. Department of Agriculture. At the time, it made sense and no one complained. After all, livestock is a private property issue just like branding. In 2012, a Texas school district began implanting the same type of RFID chips into student identification cards to monitor student movements on campus and to track them as they come and go from school.
Lyman, Wyoming was the first locale in the state to pilot the RFID program, and some parents were not happy about it.
