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. A 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.
