Visitor provides schools the facility to include a phone number field in the guest check-in process. This is an optional feature and can be turned on and off through the Kiosk settings. Simply navigate to Manage > Kiosk settings and toggle the Enable phone number field.
Once enabled the phone number becomes a mandatory field for guests to check in via both the iPad or front desk staff.
(Note that Securly Visitor cannot verify or guarantee the veracity of the phone number provided.)
