Open the Casing: Carefully cut or pry open the sealed plastic shell. Many Megane cards are ultrasonically bonded, meaning you may require a sharp blade or hobby knife to slice along the seam. Check Under Magnification: Use a magnifying glass to analyze the soldering points around the copper coil and the incorporated circuit. Try to find small ring-like cracks in the solder.
