1. An analyte monitoring device, comprising:
- a circuit board;
a radio frequency identification (RFID) chip mounted on the circuit board;
an analyte sensor coupled to the circuit board and in signal communication with the RFID chip;
a memory for storing digitally encoded data representing a monitored analyte level detected by the analyte sensor; and
an antenna coupled to the circuit board and in signal communication with the RFID chip;
wherein the RFID chip propagates a backscattering radio wave including the digitally encoded data representing the monitored analyte level when the RFID chip is within a predetermined range of a radio frequency (RF) power signal.
