Ranchers have lost their appeal in a case against USDA that alleges the agency violated the Federal Advisory Committee Act, or FACA, in its effort to mandate radio frequency identification eartags. Identification is required on all adult cattle and bison entering into interstate commerce. But current law gives producers flexibility in deciding which type of identification to use, including low-cost metal eartags. R-CALF USA has strongly opposed a mandate for the exclusive use of RFID, saying it would be costly and burdensome to producers and a case of government overreach to...

In this video, RFID (Radio Frequency Identification) Technology has been explained. So, in this video, what is RFID, what is inside this RFID system, how RFID works, and the application of RFID have been explained. What is RFID? RFID is the technology that works on radio frequency and it is used for the auto-identification for the different object. The RFID system mainly consists of two parts. 1) RFID Reader or Interrogator 2) RFID Tags In this RFID system, this RFID reader continuously sends radio waves of a particular frequency. If the object, on which this RFID tag is attached is within the range of these radio waves then it sends the feedback back to this RFID reader. And based on this feedback, the RFID reader identifies the object. RFID tags: Now, three different kinds of RFID tags are commercially available. 1) Passive tags 2) Active tags 3) Semi-passive tags These passive tags do not have any power supply. They used to get their power from the incoming radio waves from the Readers. While active tags have a power source for their internal circuitries. And for sending the response to the reader also, it uses its own power supply. In the case of semi-passive tags, they have a power supply for internal circuitries, but for sending the response it relies on the radio waves received from the Reader. Operating Frequency: This RFID system is mainly operated in three frequency bands. 1) LF: Low-Frequency band 2) HF: High-Frequency band 3) UHF: Ultra High-Frequency band The exact frequency of operation varies from country to country. Operating Principles: Most of the RFID systems operate on any of these two principles. 1) Load Modulation 2) Backscattered Modulations Applications of RFID: 1. Institutions: Library, Hospitals, Schools, and Colleges 2. Transportation and Logistics 3. Access Control 4. Sports 5.
