Abstract
In some aspects, an analyte sensor is provided. The analyte sensor has a plurality of fuse members associated therewith. The fuse members may be burned in sequence and the burn values (related to current, voltage, or time) may be used to extract/decode information. The decoded information may include calibration constant, expiration or manufacture date, counterfeiting codes, warnings, etc. Systems and methods for burning and detecting such burn values of the plurality of fuse members and decoding the coded information related to the sensor are provided, as are numerous other aspects.
