摘要：
A method of assisting with authenticating a workpiece is provided. In another aspect, ions are generated, accelerated in an accelerator, an isotope is created, and then the isotope is implanted within a workpiece to assist with authenticating of the workpiece. A further aspect includes a workpiece substrate, a visual marker and an isotope internally located within the substrate adjacent the visual marker.
