Self Service

Summary
Self Service is an app installed on the Smart Sign iPad displays at Apple Stores. Smart Sign iPads show product specs in Apple Stores. Self Service is from JAMF Software. It's part of the Casper Suite of applications. Basically, an administrator maintains apps, settings, policies, etc. on a server, sets them as "Self Service" and they'll show up in the app and then the end-user can install/reinstall them whenever they want without having to have admin privileges - this is beneficial for corporate use.
