You know those tags that they put on stuff in shops < RFID's?(the ones that are a barcode/sticker) that beep when you try and leave the shop without paying?
Well they are an aerial (open one up/peel one off and see the metal coil) and they are coded.
They are shrinking those so small that they can be sprayed onto large groups of people(such as protestors) to 'TAG' them and then these people can be tracked through transport hub such as train stations and airports to see where they are heading.
A basic hand held device can track a person 'tagged' from 1km away.
Those new passports with the same device in them can also be scanned and information stolen from them.
OBAMAS GOING TO GET YOU!!!!!!!
