What is a common requirement for security officers to wear on their uniforms?

A common requirement for security officers to wear on their uniforms is identification reflecting their role. This is crucial in establishing the officer's authority and recognizing their position within the organization. Proper identification helps both the public and other personnel identify security officers quickly, ensuring that they can be approached for assistance or commands can be followed without hesitation. By displaying identification, security officers also contribute to a professional environment and promote trust among staff and visitors.

While hats with company logos, compliance badges, and security vests may serve specific functions or enhance visibility, they do not inherently convey the officer's role in the same straightforward manner as identification. Identification serves a primary purpose of indicating the officer's capacity and function within the security framework, which is why it is emphasized as a common requirement for their uniforms.
