We might be worried about the arrival of RFID in our daily life, but our kids will probably feel very comfortable in a Big Brother world.

First, because they are getting increasingly tagged. When it's not for safety reasons, it's for fussless entertainement in amusement parks. Kindercity, in Switzerland, tags its young visitors with RFID microchips. As soon as children approach a particular attraction, the bracelet is activated. They are identified, and the price of the entrance is automatically taken from their account (just like an electronic wallet.)

Getting older, teenagers might want to be RFID'ed to gain access to nightclubs or bars.

But what could be decisive for the adoption of RFID by younger ones is the fact that the tech is now being integrated into some toys. Take Naoru-kun, a new doll by Bandai, it speaks 150 phrases and responds when it's shaken hands, hugged, petted, etc. But when Naoru-kun gets sick, kids have to use one of the items including "syringe," "candy" and "medicine." The doll reads RFID tags embedded in these items and responds accordingly.

Little Tikes has a series of toy kitchens full of interactive technology. The MagiCook Kitchen, for example, comes with pretend food embedded with electronic tags that can be read by sensors on the stovetop which then respond with the appropriate comment.
