I am curious to the name of the actual mechanism, how it is constructed, and works.
they also are called – Key Reels
or – ID Reels
the same idea is at play in the "Retractable leash".
The thing that allows the chord to be pulled out, locked, released and retracted is called a tensator spring. It looks rather like a clock spring, but can be wound and unwound a much greater distance although the retraction force is a lot less than that of the clock spring. I think its named after the company that invented and manufactures it.

*A badge reel, or retractable badge reel offers the greatest placement flexibility for anyone who has the need to display their ID card during business hours.
-The advantages of a badge reel over a strap clip or lanyard are that you can swipe the card through a reader or touch it to the reader without removing it from the attachment or holder. One has a much smaller risk of losing the card.
*A badge reel can be used together with a lanyard, strap clip or badge holder to meet everyone’s needs. Take the time to find the attachment most suited to your users needs. In many organizations, more than one system is in use.
What cord length on the badge reel should you look for?
Badge reels cord length’s are from 15” to 36”. Unless the badge reel is used with a lanyard, a 15” cord length is too short to be useful. Look for a badge reel with a 36” cord length that will meet everyone’s needs. These longer length badge reels can be found at the same price as those with a short cord.
