Hmmm...I'm not sure I like the idea of this. It almost seems like another step in giving the government more and more power which is the exact opposite of what the founders of the constitution wanted.

this technology won't be that different from current ways of tracking.
a majority of people already have cellophanes, credit/debit cards nic IDs and so on
the technology to track is out there and in full use already. this isn't too different.

how ever this allow for a greater technological development. things such as ATMs and other automated / mechanical interactions would become a lot easier to use.

especially moving towards an automated future

as for security / ability to hijack is always a concern with any technology.
personally i don't believe in a flawless or a 100% secure environment, technology, or system

as for the big brother
what you should be concerned about is the laws and governmental restrictions on the technology
things such as allowing the government to freely look through archives of your emails / web browsing, history of calls, credit information, gps.....
currently there is definitely abuse of this. where government or whoever gies behind the laws to access and search through this information
they just can't do much about it because the second they do its a violation and exposing that they did something they wern't supposed to

RFID tags sound great until you have a look at their weak points.

Current tags, 1sqm in size are great, get a metalic plastic bag and they sit inside waiting to be activated as you walk through the detectors. Has happened here in the UK.

Future tags well think of the research that has gone into electronic counter measures and you will see the problems of trying to use these tags against a technically aware population. False numbers, you don't like the ID number your coat is sending out? change it to another. Make the 'THEM' wonder why you're wearing a blender in the rain. Signal blocking, prevent the tag receiving the querying signal or sending its answer. suddenly you're clothes are invisible. This might lead to charges of indecent exposure, but I'd like to see the witnesses argueing in court. There are so many techniques for defeating these things that I don't know where to start.

I don't thnk that RFID tags are anything to worry about just yet.

The PENI tag is a passive tag with an embedded antenna. It is only 2.2[mm] on a side and claims a range of perhaps as far as 100 meters.

RFID DETECTOR NETWORKING

Current RFID detector systems like toll booths, inventor control, and delivery services could be networked to form such an integrated network. In the future RFID cash registers and cell phones could be integrated. PENI tag compatible systems would likely have greater range.

The information such a RFID network would gather is very valuable. It is unlikely that such a potentially profitable system will not be implemented.

RFID AMBER ALERT

All of the networked detectors could be instructed to alert the police if they detect the unique RFID code for the victim’s DNA samplers. Such a system could provide a fast acting and wide spread active search for the victim’s DNA samplers.

DNA DATABASES

Kidnappers, rapists, and assailants would be venerable to this network through the RFID tag in the DNA samplers. The recovered DNA would be fed into a DNA database for matching or stored as a cold case for future matching. It might be possible to identify a suspect with a ‘near hit’ on a close relative already in the DNA database.

Whether the RFID network would be used abusively or not is not affected by using it to locate DNA samplers. The RFID network might as well be used to identify violent criminals. Otherwise, it is just a wasted opportunity to prevent violent crime. Kidnappers, rapists, and assailants will go free and their victims will not be rescued.
