An analyte test sensor strip is disclosed having information coded thereon as well as a method of forming the same and conducting an analyte test using the analyte test sensor strip. Information relating to an attribute of the strip or batch/lot of strips may be coded based on resistance values pertaining to electrical aspects of the strip, such as a primary resistive element and a secondary resistive element, the secondary resistive element having one of a plurality of states defined by a location of a closed tap to form a unique resistive path for the secondary resistive element that includes a portion of the primary resistive element depending on the location of the closed tap. The states may be formed on the strip by a secondary processing step in the manufacture of the strip in which a plurality of taps are severed leaving only one tap in a closed state.
