• Vital Warning: Be very mindful near the top edge of the card where the internal antenna coil is positioned. Slipping with a knife can sever the great copper wire, rendering the card entirely worthless.

Action 2: Inspecting the Circuit Board

When the plastic shell is divided open, carefully move out the internal printed circuit board (PCB). Use a magnifying glass or a mobile phone electronic camera zoomed in to examine the board. Look for:

• Micro-fractures in the solder joints, particularly around the IC chip and the internal battery holder.
• Loose elements that wobble when carefully nudged.

Action 3: Resoldering Faulty Connections

• Warm up a fine-tip soldering iron.
• Apply a tiny quantity of fresh electronic solder flux to the suspect joints.
• Thoroughly reflow the solder on the weak connections. The objective is to remelt the existing solder to bridge any tiny cracks that are blocking electrical continuity.

Step 4: Testing and Reassembly
