Abstract: The invention is directed to an improved RFID system. The system provides a transponder that 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 improved apparatus and method that allows the end user to customize and program identification tags. The system also provides an ear tag, which may be in button form, for use on livestock with superior durability and overall performance in the field. The present invention also relates to a flexible and/or implantable radio frequency identification system, such as a flexible and/or implantable radio frequency identification system for tracking animals.

Abstract: The present invention relates to a flexible and/or implantable radio frequency identification system, such as a flexible and/or implantable radio frequency identification system for tracking animals. The present invention relates to a printing system for animal tags, and methods employing the system. The system includes a printer and processor. The processor is configured to direct printing by the inkjet printer on an animal tag of a government identifier and producer specified indicia upon demand by the producer. The printer is configured for durable printing on an animal tag.
