Warning: Be exceptionally careful not to cut too deep, as the internal circuit board sits very close to the external edge.Examine the Circuit Board: Once split open, analyze the board under a magnifying glass. Resolder Loose Components: The most frequent internal problem is broken solder joints on the microswitches or the battery real estate, generally caused by the card flexing in a back pocket. Utilize a soldering iron to reflow the solder on these connection points.Check the RFID Coil: Look closely at the great copper wire running around the perimeter of the board.
