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.

Abstract
A glucose monitoring system, includes a glucose sensor strip or package of strips. The strip includes a substrate and a glucose monitoring circuit that has electrodes and a bodily fluid application portion of selected chemical composition. An antenna is integrated with the glucose sensor strip. An RFID sensor chip is coupled with the glucose sensor strip and the antenna. The chip has a memory containing digitally-encoded data representing calibration and/or expiration date information for the strip.
