ID Badges

What is this name for this cord reel that came with my ID badge?

So at work when I got my ID Badge it came attached to this reel that automatically retracts a nylon cord. By design it keeps my badge attached to my pant waist but allows me to pull the ID up to a security sensor so I can access certain areas and then retract the cord returning the card to my waist. What are these little devices called?

1. Badge Reels. A web search pulls up lots of companies that will make custom designs for you or sell standards. As far as brick and mortar stores, Office Depot has them.
