Some parents decry new Carroll schools’ palm scanner
They say system to pay for lunches is violation of privacy
Instead of paying for their lunches with crumpled dollar bills and loose change, students in Carroll County schools are having their palms scanned in a new check-out system — raising concerns from some parents that their children’s privacy is being violated.
The county is one of the first localities in Maryland to use the PalmSecure system, in which children from kindergarten to 12th grade place their hands above an infrared scanner. It identifies unique palm and vein patterns, and converts the image into an encrypted numeric algorithm that records a sale.
Though the school system does not store those images, some parents have complained about the implications of having their children’s hands scanned. About 20 percent of parents have declined to participate in the program, said supervisor of food services Karen Sarno.
