Abstract
An insertion pin includes a pin member on which a circuit board, an inspection antenna, and an inspection chip are mounted. The circuit board includes a main circuit, a main chip, and an inspection circuit set in an open-circuit condition with respect to the inspection antenna and the inspection chip. A lock base includes a main antenna matching the main chip. When the lock base and the pin member are combined and locked together, the main chip is electrically connected with the main antenna to emit a first signal for monitoring with an identification device, and the inspection circuit is electrically connectable with the inspection chip and the inspection antenna to emit a second signal to allow a mobile phone to carry out quality control to determine if the first signal is in normal operation. Cutting off the insertion pin terminates both the first and second signals.
