A Maryland school district has removed palm scanners from 12 school cafeterias where the devices were in use, following backlash from some parents. Now, the district has installed point-of-sale computerized cash registers in cafeterias, for use during the upcoming school year. The devices allow students to input a five-digit PIN number in the cafeteria line to access their meal accounts.
