Another Touch-Screen Interface Design: Fingerprint Authentication

After beating a couple of different log-on ideas back and forth, our design team finally decided that the best option would be touch-screen fingerprint authentication, as seen below.  Each nurse and hospital staff member who regularly uses the device is logged into the system, and as such, only those who work in the hospital can log on with their unique finger print.  This allows multiple users to share the device, but at the same time this deters theft of the device, as no one outside of the hospital would be able to use it.  While nurses are in charge of utilising Juvo, our enterprise (the external third party delivering this service) is in charge of managing and maintaining the information systems side of it, making sure that the technology keeps working so that the nurses don't have to worry about it.  Anyway, here's a view of the log-on authentication screen:
