School supplies: Lined paper, No. 2 pencils and radio-frequency tracking chips.
Until someone offers a valid reason to tag schoolchildren with tracking microchips, this technology is better left for finding Fido once he jumps the backyard fence.
A San Antonio, Texas, school district has embedded locator chips into student ID badges to better police hallways. It now faces a legal challenge by fundamentalist Christians on a religious ground (the chips and cards are a sacrilegious “mark of the beast”). The American Civil Liberties Union also objects out of privacy concerns.
