1. A remote detection system, comprising:
- a transceiver configured to send and receive radio frequency signals;
a transponder configured to receive radio frequency signals from the transceiver and to send radio frequency signals to the transceiver;
a fuse within one of the transponder and the transceiver;
wherein the transceiver is configured to send radio frequency to the transponder thereby preventing the fuse from blowing while the radio frequency signal is received.

Abstract
A system for remote detection using and RFID system including a transceiver, a transponder and a fuse configured within the transponder. The transceiver is configured to send and receive radio frequency signals. The transponder is configured to receive radio frequency signals from the transceiver and to send radio frequency signals to the transceiver. The transceiver is configured to send radio frequency to the transponder thereby preventing the fuse from blowing while the radio frequency signal is received.
