Some dart-firing stun guns have a built-in feature for cartridge identification. What is it?

• A. Owner authentication module
• B. Cartridge identification system
• C. GPS tagging system
• D. Battery health monitor

Answer: (B)

The built-in feature is a cartridge identification system. This reads data from the loaded cartridge—such as its model, batch, or serial information—and communicates it to the device. That lets the stun gun verify the cartridge is appropriate and safe to deploy, and it can log which cartridge was used for records or debriefs. This is why it’s the best answer: it specifically identifies the cartridge to ensure proper operation and traceability. Other features, like owner authentication (user access), GPS tagging (location tracking), or a battery health monitor (power status), don’t identify the cartridge itself.
