Abstract

The present invention relates to a biosensor. The biosensor includes a support substrate, an electrically conductive coating positioned on the support substrate, the coating being formed to define electrodes and a code pattern, wherein there is sufficient contrast between the conductive coating and the substrate such that the code pattern is discernible, and a cover cooperating with the support substrate to define a channel. At least a portion of the electrodes are positioned in the channel.
