RFID ternyata sudah dipakai sebagai mesin absen di sebuah SD di Tokyo. Detektor di gerbang sekolah akan mendeteksi setiap siswa yang keluar masuk berdasarkan "tag" yang dibawa siswanya. Komputer akan merekam log dan mengirimkan email ke orang tuanya (jadi orang tua tahu bahwa anaknya masuk sekolah).
Akan tetapi, menurutku, kalau si anak keluar sekolah tanpa membawa RFID tag-nya? Sistemnya menjadi kurang berguna.. :-) Ini sudah biasa di sekolah2 kita, terutama di kota besar, kalau anak sekolah datang pagi2, kemudian saat jam istirahat mulai main2 keluar sekolah (ke mal, dll). RFID device-nya perlu ditanam di dalam tubuh? ---------------------------------------------------------------------------------------------------------- http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20041014f2.htm Students tagged in bid to keep them safe Radio frequency chips track comings and goings for anxious parents Every time a fourth grader passes through Rikkyo Elementary School's front gate, a small, gray plastic tag tucked inside his backpack beams a message to a computer in a nearby office. The students are oblivious, but the computer logs the time they enter and leave, and a security guard watching the screen takes note. Moments later, their parents receive confirmation by e-mail. Rikkyo officials hope the Radio Frequency Identification technology will serve as an early warning system for children who go missing.
