1. A system, comprising:

  • an information technology asset; and

    an active radio frequency identification (RFID) tag, comprising;

    a power source;

    a data storage repository;

    a radio frequency (RF) transmitting element configured to transmit data from the data storage repository, and electrically attached to the power source;

    a thermal to electrical energy converter electrically attached to the power source, wherein the thermal to electrical energy converter receives thermal energy from the information technology asset and is a second power source for the RFID tag; and

    a capacitor electrically connected to one of the power source or the thermal to electrical energy converter, wherein the RF transmitting element transmits the data upon the capacitor being recharged to a threshold.
