This generation of Tamperproof EID Tag has a unique design that provides the ultimate in usability, security and retention. This single use tag features a hard plastic Tamperproof cap. Transponder numbers are laser marked in a circular format on the edge of the tag.

Half Duplex Technology (HDX) is utilized with the High Performance Ultra EID Tag. HDX is a design principle whereby the transponder initiates the return signal to the reader/scanner/interrogator only after the end of the interrogation signal has been received and only after the storage capacitor has been fully charged in the transponder. The return signal is then only sent once, since the transponder has emptied its storage capacitor after it has sent its entire data content. This proven High Performance technology provides enhanced signal strength for maximum read distance.
