At work we have a chain-link key card access bike lockup in the parking garage. Security does a walk-by every 30 minutes and must scan a QR code inside the cage. In the cage most of us leave U-locks to use. I keep an extra in my locker in case mine is messed up when I arrive.
The lockup is not infallible and I wouldn't leave it overnight, but during the day we have a good track record for avoiding theft. I mean a guy with bolt cutters could snip the cage's chain links in couple of minutes, on camera.
