1. A sensor system for measuring an analyte in a host, the system comprising:

  • a sensor configured to measure an analyte concentration in a host;

    sensor electronics operably connected to the sensor, wherein the sensor electronics are configured to produce a data stream indicative of the analyte concentration in the host and an RFID chip configured to identify the sensor and to transmit a signal including the identifier and the data stream to a receiver; and

    a receiver configured to receive transmissions from the sensor electronics, to download the data stream, and to control the user interface by displaying the analyte concentration from the sensor, wherein the receiver is programmed to confirm sensor insertion prior to display of the analyte concentration, and wherein the receiver is configured to identify the sensor insertion based on the data stream.
