Our system checks cell phone number and/or email address in a duplicate-check to make sure that this guest is not entered twice. If the guest’s email or cell phone match an existing record, a prompt will show asking if the existing record is the same guest that is attempting a new sign-in, or if they are related to the guest, and it will give options from there to either check in as the existing guest, or add a new guest as a family member or other related record type.
