Abstract:
1. An RFID-enabled utility device interface unit configured to receive measurements from a utility meter, the meter interface unit comprising: (a) a main power source that is not a radiofrequency induction power source; (b) a memory storage device comprising a plurality of memory addresses in non-volatile memory connected to receive power from the main power source, and configured to periodically record a measurement from the utility meter in the non-volatile memory when powered by the main power source; and (c) an RFID connected to the memory storage device to read the memory storage device and to provide radiofrequency induction power to the memory storage device, configured so as to provide the radiofrequency induction power to the memory storage device in response to a signal from an interrogator, configured to transmit the measurement that is recorded on the memory storage device in response to a signal from the interrogator, and wherein the RFID is configured to receive a signal from the interrogator that designates a memory address as write-protected against the recordation of any data not transmitted by an interrogator.
