I've always found the selective paranoia of technophobes to be strange. I would bet that the kids who object to the RFIDs are probably carrying smartphones that can be tracked just as easily: http://www.pcworld.com/article/255802/this_smartphone_tracki... These RFIDs are even easier to disable than cell phones since they can just be kept in a metallic pouch when not needed, but it's much more difficult to keep a smartphone in airplane mode all the time.

These people remind of other technophobes who are afraid of radiation from WiFi and cell phones for "health reasons" but don't have a problem with sunbathing. The school should just invest in some science and technology classes rather than trying to argue with these people.
