Identification Method for Electrochemical Test Strips
First Claim
1. A method of making a plurality of test strips wherein said test strips are part of a base test strip group or a modified test strip group distinguishable from the base group comprisingcreating a plurality of base test strips, each with a region of electrically conductive material, and a plurality of accessible contact points connected to one another by said electrically conductive material;
- andmodifying a portion of the base test strips by physical removal of electrically conductive material or at least one contact point to create a first modified test strip group wherein the test strip within the modified test strip group is distinguishable from the base test strip due to a difference in electrical conductivity/resistance between the contact points.

Abstract
The present invention provides a method and apparatus for creating test strips that may be identified based on differences in electrical conduction or resistance between contact point on the test strip. This is achieved by creating a base test strip with contact points that may be connected to other contact points by an electrical connection. These base test strips may be modified to create a difference in electrical conductivity between contact points, or a contact point may be eliminated. This modification can be used to distinguish different types of test strips based on electrical signature. Additionally, the base test strip may be created such that multiple modifications are possible to distinguish numerous characteristics of test strips.
