Before you can use the sign in tablets at the entrances to the college, you will be issued with an NA College ID badge. To sign in, simply tap the badge on the contactless dongle that is attached to the tablet. If you are signing in, the tablet will respond with "Have a great day", and if signing out it will respond with "Goodbye".
You should tap in or out each time you arrive at or leave the NA College site.
If you prefer, you can also use the sign in app to sign in and out. Please see the Sign In tablets which provide on screen instructions of how to do this.
