I've seen some companies that clock the hours you're "in the building" and allow coming up early to leave early.
What happens in practice is that some people will come in early, start working early, and leave early. Some other people will check-in early, enjoy the office-provided amenities in the empty office, and actually start working when the rest of the team gets in the office.
Some smarter company just ask you to check-in before, say, 10 am and don't care when you leave (either early or late -- and don't require you to check-out explicitly by passing the badge) -- it's up to you and your boss/manager: as long as you meet the deadline, leave as soon or as late as you see fit.
