You need it to take tests eat, and make other purchases. So what happens when you lose your student ID card? At most colleges you pay a replacement fee. For Louisiana State University students, that amounts to $15, a figure some students don't like. Getting a card to last the eight semesters a student attends college could be problematic for some.

"It seemed a little expensive to replace," said one LSU student.. "I have to have it to take tests and eat."

Yet, it's hardly a cash cow for LSU, since it costs the university $11.49 to produce each card. The remainder of that $15 replacement fee goes into a fund for software and equipment upgrades.

Some 6,600 students contributed to that fund last year, LSU's The Daily Reveille reported. Read more here.
