Harnessing Subatomic Effects for Product Authentication

Anon writes: "Israeli company Microtag claims to have come up with a way to avoid counterfits, and they mean everything from CDs to clothes to cash to vegetable seeds. Mix several micrograms of their 'magic powder' - which is engineered with a unique identification using the matter's spin - into your product - and later you can verify its authenticity with a relatively low-cost reader. Although their presumption is that no-one else will be able to create this 'magic powder' (which is probably only a matter of time and enough money), an Israeli article claims that Motorola and even the Bank of England are interested in the technology."

Submolecular not subatomic.

[Bazzargh]

The system is clearly based on resonant frequencies of bonds in the molecules of the taggant. They actually say 'submolecular' not subatomic on their site.

Someone else mentioned that this makes sense if you say UV instead of RF - well that may be true but its hardly new. Here for example is a UV taggant that works on that principal.

It may well be that their selling point is that they _are_ using RF taggants because its too easy to check if a UV taggant has been applied to something (one of the uses of UV powder tags is to check which employee has touched eg a secure terminal. You have been warned!)
