1. A method, comprising:

  • providing a radio frequency identification (RFID) tag, the passive RFID tag comprising an RF network node, wherein the RF network node includes an RF and analog block for receiving and transmitting an RFID reader signal, a data processing and controller block for digital information processing, a memory store, and a power management block for managing power requirements of the RF network node;

    during operation of the RFID tag, using the power management block to dynamically control the distribution of power to and from the RF network node functional blocks by selecting between an extended operational time and an increase in available functionality;

    storing information in the memory store, wherein the memory store includes a plurality of one time programmable (OTP) memory locations for the storage of information to be communicated from the passive RFID tag to an RFID reader in response to an interrogation from the RFID reader, and wherein the memory store further includes memory for storing memory location information that provides a memory location of information stored in the plurality of OTP memory locations.
