“Operating like a time clock, a wireless integrated circuit (IC) tag measuring 6 by 3 centimeters and attached to a knapsack or carried in a pocket automatically registers when the child enters or leaves the school.
Using an Internet connection, teachers and parents can then check what time a child arrives at school in the morning and when he or she leaves in the afternoon. The information can be sent to up to three e-mail addresses.
In late September, Rikkyo Primary School, a private school in Ikebukuro, Toshima Ward, Tokyo, handed out tags to 40 fourth-grade students. This month, the experiment will be expanded to include about 120 students, or one-sixth of the student body. Every child at the school is expected to be in the system by April 2005.”
