Smart Mobs: Train ticket tracks kids:
When a kid passes through RFID-enabled train ticket gates using an PiTaPa train pass, which is an RFID card, an SMS message is automaticaly sent to their parents.
Oh, pretty please — don’t implement this down at HawaiiBio. I’m sure my mom could do without an SMS saying “your son just spent some of the money you gave him on naked titties”…
