Abstract

An analyte monitoring system includes an analyte sensor, a transceiver, and a display device. The analyte sensor may include an analyte indicator that exhibits one or more detectable properties based on an amount or concentration of an analyte in proximity to the analyte indicator. The transceiver may receive first sensor data directly from the analyte sensor and may calculate first analyte information using at least the received first sensor data. The display device may receive second sensor data directly from the analyte sensor and calculates second analyte information using at least the received second sensor data. The transceiver may convey the first analyte information, and the display device may receive the first analyte information conveyed by the transceiver and display the first and second analyte information.
