Somewhere on your campus there is, very likely, a magnetic stripe stored value system in operation. Maybe it is a full-blown part of your campus ID card enabling cashless purchases in vending machines, photocopiers, and laundry facilities. Or maybe it is a stand-alone system for copiers in some renegade department, an internal control device for tracking departmental office equipment usage, or on the back of a dedicated library card issued only for use in the law library. Whatever the case, the little black stripe is likely on the back of some plastic cards on your campus.
