• Crucial Warning: Be extremely cautious near the leading edge of the card where the internal antenna coil is positioned. Slipping with a knife can sever the fine copper wire, rendering the card entirely ineffective.

Action 2: Inspecting the Circuit Board

Once the plastic shell is split open, gently slide out the internal printed circuit board (PCB). Utilize a magnifying glass or a mobile phone cam focused to examine the board. Try to find:

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

Step 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 goal is to remelt the existing solder to bridge any tiny fractures that are blocking electrical continuity.

Step 4: Testing and Reassembly
