Have you seen the poster asking you to tap in and tap out?

The Health Sciences Library is collecting data on traffic patterns in the library by asking that you tap in and tap out with your ID card each time you come to the library. This simple step will help us to better understand who is using the library, when and for how long, informing future space planning.
