• Essential Warning: Be incredibly careful near the top edge of the card where the internal antenna coil is positioned. Slipping with a knife can sever the fine copper wire, rendering the card totally worthless.

Action 2: Inspecting the Circuit Board

As soon as the plastic shell is split open, gently slide out the internal printed circuit board (PCB). Use a magnifying glass or a mobile phone electronic 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 elements that wobble when carefully pushed.

Step 3: Resoldering Faulty Connections

• Heat up a fine-tip soldering iron.
• Apply a small amount 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 microscopic cracks that are blocking electrical connection.

Step 4: Testing and Reassembly
