Credentials are ID passes which identify volunteers and staff and allow them access to the appropriate places at your projects. This panel shows all of the credentials printed for this person, along with the type, date printed, date expired and project.
The information on this panel is generally read-only, meaning that you can't edit it here. To print a new credential, follow the Printing Name Tags, Badges and Credentials instructions. The only change you can make here is to mark a credential as cancelled, which will make it unusable for signing in via a kiosk. To cancel a credential, right-click on it and select Cancel this credential. Once a credential is marked as cancelled and it's been saved, it can not be un-cancelled in the future.
