the hitachi company have developed the worlds tiniest radio id tag, they say its not for release but what is the purpose of such a tiny thing? why so small ?this is as small as a spec of powder so they could track an ant in theory.
but why ? whats the point of it it fuels the curiosity of my conspiracy theorys mechanisms.

The minute devices measure just 0.05mm by 0.05mm (0.002x0.002in) and to the naked eye look like spots of powder.

They are thin enough to be embedded in a sheet of paper, Hitachi spokesman Masayuki Takeuchi says.

RFID tags store data about the objects they are attached to, and companies are vying to create increasingly tiny versions.

Recently, Hitachi unveiled another RFID tag, the Mu-chip, which measures 0.4mm by 0.4mm (0.02x0.02in).

But the latest chips, which are yet to be named, can hold the same amount of data as the Mu even though they are much smaller.

They have one major issue, however - they need an external antenna to work, and the smallest antenna developed so far is about 80 times bigger than the tags.

Hitachi says it wants to study the tags' possible uses, but it does not yet have any plans to put its latest creation into commercial production.

Spy-tags

Unlike its predecessor, the barcode, an RFID tag's data can be extracted from afar - sometimes from hundreds of metres away - by radio-reading devices, and the technology is already widely used.

Stores use it to track stock in warehouses and shops. Some countries are using the tags to hold passport data or for payments in transport systems, and they are even being used for animal identification.

However, some have raised concerns that the technology poses a threat to privacy, and that it could be used in covert monitoring schemes.

And the fact that they are becoming ever more invisible could fuel this apprehension.

However, said Mr Takeuchi: "We are not imagining such uses." YEAH RIGHT!!

I saw that article. It is a little frightening, isn't it? It could be used to track people or anything for that matter if a government had the desire to do it.

I'm sure the US Govt will hold on to it. And purpose, it'll confirm be to track any criminals or suspects.

There goes our privacy...

like we had privacy anyway, its just that virtually every piece of new technology that has ever been invented or discovered always gets misused.
im very very mistrusting of big brother and its intentions for my offspring and the way in which it intends to sheer us like sheep in the future.
this kinda stuff tells them even more as if they didnt have enough already.

Ever hear of the RealID that the neo-cons are trying to push on us? Well, they would use RFID chips to store a lot of personal information (Not to mention track your every move). They have already made devices that can steal information off of an RFID chip by simply walking past the subject. Newer passports also contain them but it is legal is destroy the RFID chip amid safety concerns. These might be good for for stock and other commercial items but the idea for using them to store personal information is outrageous.

What privacy?

very interesting.........
i didnt saw that article before
