A Central Florida school district has apologized after some students’ irises were scanned as part of a pilot security program without their parents’ permission. High-tech eye-scanning cameras were installed on school buses at Davenport School of the Arts, Daniel Jenkins Academy and Bethune Academy in Polk County. The children’s irises were scanned May 23. In the program, a number is assigned to that student and that student’s information. The district could then track the student’s movements on and off the school bus and notify parents whether a child returned home on time.
