What type of identification is required for a registered employee working armed?

A registered employee identification card is the correct answer because it specifically serves as official proof that the individual is authorized and trained to carry a firearm while on duty. This identification is crucial for ensuring that the employee has met all necessary qualifications and compliance requirements set by regulatory bodies, which often include background checks and training verification.

While an employee employment badge, a driver's license, and a military ID may serve as forms of identification, they do not provide the same level of assurance regarding the individual's qualifications and registration status in relation to armed duties. An employment badge might identify the individual as a member of a company but does not necessarily validate their ability to carry a firearm. Similarly, a driver's license and military ID are personal identification documents but do not indicate that the person is registered and trained to work in an armed capacity. Hence, the registered employee identification card is essential to meet both legal and organizational requirements for armed roles.
