The Palm Beach County, Fla., school district is considering implementing biometric fingerprint scanners for a variety of student functions, including bus service, library usage, attendance and lunches.

As written on EdWeek’s Digital Education blog, the school district surveyed its principals and found that 60% wanted to add biometrics for a variety of student uses. Based on the survey findings, the district will ask the Board to run a pilot to test its viability.

This isn’t Palm Beach County’s first attempt to try biometrics. It has tried pilot programs in certain school cafeterias, but stopped because the system required parent approval and few parents opted into the system.

The school district serves 171,000 students.
