Abstract
An RFID system provides a transponder having a power store that can be recharged when located within an electromagnetic field generated by a transceiver unit. The power store can be a battery and/or a capacitor. In certain embodiments, the transponder can communicate over at least two different frequencies so that the real time performance of the transponder can be improved without losing backwards compatibility. The system provides an ear tag for use on livestock with superior durability and overall performance in the field.
