First they came for the prisoners . . . But, instead of being contained in bracelets worn around the ankle, the tiny chips would be surgically inserted under the skin of offenders in the community, to help enforce home curfews. The radio frequency identification (RFID) tags, as long as two grains of rice, are able to carry scanable personal information about individuals, including their identities, address and offending record. The tags, labelled "spychips" by privacy campaigners, are already used around the world to keep track of dogs, cats, cattle and airport luggage, but there is no record of the technology being used to monitor offenders in the community. The chips are also being considered as a method of helping to keep order within prisons. http://news.independent.co.uk/uk/politics/article3333852.ece Sure, prisoners give up rights. but once they use this technology for prisoners, what is to stop them from using it for ordinary citizens? civil rights activists will protect citizens, you say? who's next?
