Kids lose their school IDs but they don't often lose their eyeballs.
That's one of the reasons why a growing number of schools are replacing traditional identification cards with iris scanners. By the fall, several schools -- ranging from elementary schools to colleges -- will be rolling out various iris scanning security methods.
Winthrop University in South Carolina is testing out iris scanning technology during freshman orientation this summer. Students had their eyes scanned as they received their ID cards in June.
"Iris scanning has a very high level of accuracy, and you don't have to touch anything, said James Hammond, head of Winthrop University's Information Technology department. "It can be hands free security."
The college will be deploying scanning technology from New Jersey-based security.
