Two weeks ago I bought a Yoga 720 and it has worked fine (including the fingerprint scanner). Three days ago it just stopped working. Now the Windows Hello says that my device doesn't support that feature. In the device manager it indicates that the Windows can't load the driver (Code 31?). I have been trying to reload the drivers for the fingerprint scanner from Lenovo without success. Any help would be greatly appreciated.

I had the same problem with the 920 when I first ran windows update. I just uninstalled the driver from the device manager and made sure the delete driver checkbox was checked.
I downloaded the driver from the support section under fingerprint reader: Yoga 720 Drivers
After the install I rebooted and it was working again.

I tried the uninstall and delte drivers. However, I used the windows related driver. BUT, I did get it fixed by resetting the whole PC. I'm in the process of setting it back up, so if it happens again I will try to download the drivers from Lenovo first!
