A substrate verification system is utilized for verifying substrate location and orientation in a catalytic converter mat wrapping mechanism. A mat wrap mechanism reads data from a substrate. A verification mechanism compares the identifier data with stored data. If the substrate is verified as correct, the verification mechanism activates the mat wrap mechanism. If the data from the substrate does not match the data in a system an alert is activated. If there is an error, the wrapping process will not be activated. The present invention therefore provides a substrate verification system for verifying substrate location and orientation.
