Administrators at a North Jersey school have calmed privacy concerns after a school in Englewood started using biometric readers to authenticate meal payments.The school installed the reader after abuse of a card system, with pupils that were permitted free meals swiping in for their friends.Parents have said at a local meeting that there hasn't been enough outreach over the new devices.Lucy Walker, an Englewood resident, said at a 22 September Board of Education meeting: “How do you opt out of something you don't know about?”Resident Curtis Caviness said that parents were only notified of the software via an automated “robo-call.””Where's this info going, who's storing it?” Caviness asked, reported NorthJersey.com.Cheryl Balletto, the school's business administrator, said that the technology scans a combination of 18 points and converts it to a numerical data sequence.”That numerical data can then be identified, not the [fingerprint] image,” Balleto added.”There is no possibility that a student's meal could be tied to the wrong account,” reads an FAQ on the school website. “All students in the district would not have to worry about forgetting a PIN or their ID card.”The FAQ also says information gathered will remain within the school district and that it is impossible to falsify or duplicate a student's fingerprint using the student's biometric information..
