EURion Constellation: Anti-Counterfeiting Device for Money

Posted by Alex in Money & Finance on September 24, 2007 at 1:45 pm


Got a new $10 or $20 bill in your pocket? Get it out and look at the yellow numbers. You’ll notice that they’re actually arranged in a specific pattern at different orientations to prevent counterfeiting:

The EURion constellation is a pattern of symbols found on a number of banknote designs since about 1996. It is added to help software detect the presence of a banknote in a digital image. Such software can then block the user from reproducing banknotes to prevent counterfeiting using colour photocopiers.

    Ok the think I’ve never understood about creating all these anti-counterfeit methods is this…
    If you were a counterfeiter, why wouldn’t you just counterfeit some money with an older date? like money with a date from the 70’s, that didn’t have the same anti-counterfeit stuff that today’s money has.

    Yes Nora, small potato counterfeiters would do this - but that’s inconsequential to the amount of circulating dollar bills.

    the idea is to give big time counterfeiters trouble. They just can’t “move” lots and lots of old bills without raising suspicion, hence the continuous re-design of money.

    Thanks Alex. That makes sense. :D Guess I’d never make a good counterfeiter. :P
