By bringing up Visitor Details either from the View Visitors icon located at the bottom left corner of the sign-in form, or from your mobile app, you can see Visitors’ information in real-time, including social profiles of verified contacts. The main registration device must be connected to wifi so all information can be synced.
Spacio pulls social information for any contacts that we can verify. More about that here.
You may want to log out of LinkedIn or set yourself to anonymous from your LinkedIn settings before clicking on any LinkedIn profiles or set privacy so people can’t see you visiting their profile.
