The KCM provides a limited view of check-in activity.
The KCM check-in list will show all contacts that used the kiosk that day, or the last 15 contacts to use the kiosk. It does not have the option to display all check-ins for the account.
To see all check-in activity for an account, sign-in to the desired account, click REPORTS, then click KIOSK SUBMISSION LOG.
