Crucial Warning: Be very cautious near the top edge of the card where the internal antenna coil is situated. Slipping with a knife can sever the great copper wire, rendering the card entirely worthless.Action 2: Inspecting the Circuit BoardWhen the plastic shell is divided open, gently move out the internal printed circuit board (PCB). Use a magnifying glass or a smartphone camera zoomed in to check the board. Try to find:Micro-fractures in the solder joints, especially around the IC chip and the internal battery holder.Loose components that wobble when carefully nudged.Step 3: Resoldering Faulty ConnectionsWarm up a fine-tip soldering iron.Use a tiny quantity of fresh electronic solder flux to the suspect joints.Carefully reflow the solder on the weak connections. The goal is to remelt the existing solder to bridge any tiny fractures that are obstructing electrical continuity.Step 4: Testing and ReassemblyBefore gluing the plastic housing back together, take the circuit board out to the car and test it in the card reader.
