Abstract
A meter interface unit (MIU) is provided for a utility meter that uses RFID technology as both a source of backup power and as a means of transmitting utility usage data. Usage data is stored in non-volatile memory that will persist even if the main power source of the MIU is lost. Because an RFID generates electric current when it receives an electromagnetic signal from an interrogator, the RFID can provide power to the memory, read the usage data from the memory, and wirelessly transmit the usage data back to the interrogator without any other source of power. This can prevent data loss when the MIU runs out of power; for example, when its battery is expended. RFID technology can also provide many other benefits and uses when coupled with an MIU, in addition to serving as backup power and communication.
