Carried a MSFT blue badge for six years.

On the employee number - if security needs it, they can flip the badge around. I needed it once in six years, when I needed to type it into some internal tool.

On the employee status, that is done with badge color. Blue badges are FTE only.

Intern's get Blue as well, but are, for most intents and purposes, considered FTE's.

RE: the employee number - You may not have physical access to the card, e.g. you only have CCTV footage of the employee doing whatever they're doing.

That would be a really high-res CCTV...

It keeps hitting me... If you're doing something wrong, why would you be wearing your badge?
