message: Markus Kuhn "discovered" it?
This is, to me, a bit misleading.  EURion was designed by other people.  Markus was just the first public member to realise its existence.  True? —The preceding unsigned comment was added by Igitur za (talk • contribs) 12:35, 9 March 2007 (UTC)

message: British Pound or Pound Sterling? I'd prefer the second, but if there is a standard within numismatics, or another Wikipedia policy I should be aware of then I'm willing to be purseuded otherwise. --Neo 09:48, 13 March 2007 (UTC)

message: Crux, the "Southern Cross", seems more apt. This "EURion" has five points; less than the 7 points that are usually left as a minimum to describe Orion; 3 on the "belt" and 4 on the corners. The "dagger" and "head" are often included to make 9 points. Besides, Orion's corner's are  quite rectangular, unlike the more kite-shaped "EURion". Crux, on the other hand, is more kite-shaped, is known for 5 stars, is extremely useful in navigation, & is featured on the national flags of Australia, Brazil, New Zealand, Papua New Guinea, and Samoa. Why not name it after Crux, which is geometrically much closer, much more important to the countries of the world, and much more important in astronavigation? Crux has also been seen by every human's ancestors, if one goes back enough; it was even known to the ancient Greeks before millennia of precesssion in Centaurus. This means Crux kind of belongs to humanity, while euros don't even cover Western Europe, let alone its continent, Eurasia, or the world.

replies: text: If the article is correct, then I think you're about five years too late in your suggestion. After all; it is just a name and the discoverer really has a right to call it whatever he wants. --Neo 09:41, 23 August 2007 (UTC)

text: Personally, I like the name, it sounds disgusting, and it's about a security feature to randomly make photocopiers not work.  I'd like to see how exactly I would need to draw circles on someone's test to prevent the English department from photocopying it.  I wonder if any books are printed with this security feature.  —Preceding unsigned comment added by 24.91.116.134 (talk) 18:16, 26 December 2010 (UTC)
replies: text: Kind of like an "Ugly T-shirt", William Gibson-style? ;)  I'm actually curious as to if there's a move away from purely black and white (read: Infrared, also)cameras thanks to the IR LED trick.  Simply add a color filter and it'll no longer be effected by invisible radiation, but sadly at the cost of sensativity.  The constellation was obviously chosen because of geometric properties.  It has no need for odd frequency hacks (it works on existing sensors assemblies) but depends on a pretty unlikely pattern outside of money.  Another trick I've read about is that scanners have 2-line sensors and that you can find hidden patterns in a series of individual pixels with very little CPU power.  Kind of like the 32-bit error-correction coding on the old NASA space probes.  71.196.246.113 (talk) 05:34, 12 January 2013 (UTC)
thread_title:  "Orion"? 

message: This is a bit OT but the similarity of "...later noted simple integer ratios between the squared distances of nearby circles..." reminded me of something similar written about by sci-fi author Jack Vance. From my memory of reading his books, a long time ago at that, his fictional banknotes were protected by scoring (inverted ridging) across their width, from the end of the note, at a distance proportional to any four square roots of the first eleven primes. 
Trivia I grant, but fyi anyhow. 86.156.213.85 (talk) 21:23, 16 February 2008 (UTC)

message: Could somebody please indicate or verify the sources stating that Hungary has been using the EURion constellation on the 500 forint notes? I'm from there, and I've never seen a Hungarian note with the EURion circles on it, and I do pay attention to them. I checked the National Bank's website's  on Banknotes, and there is nothing that would specifically say that there was a security upgrade, the announcement of which is official MNB policy. I also checked Ron Wise's Banknoteworld.com, but there was no image of a "new and upgraded" 500 forint note. Ron's site is usually very up-to-date. As I could not find anything to prove the validity of the information on the article, I recommend it for correction. George Adam Horváth (talk) 08:30, 29 February 2008 (UTC)

message: I have found the Reserve Bank of India has officially used the term Omron anti-photocopying feature. Since EURion constellation is a made-up word by a third party, it's better to rename this article.
The International Bank Note Society uses Omron rings.  It sounds better than Omron anti-photocopying feature, but the society is a non-profit organization for paper money collectors and has no official status.
According to Owen Linzmayer of Banknote News, Omron rings is a common name and many central banks call it Omron security feature, but I cannot find an official source. - TAKASUGI Shinji (talk) 10:41, 26 June 2008 (UTC)

replies: text: I think it's because all denominations of that country's notes contain the feature. -- Arwel Parry (talk) 21:16, 25 April 2010 (UTC)
replies: text: Seems to be. I added a note at the top of the table to indicate this. Zabacad (talk) 04:55, 2 May 2013 (UTC)
replies: text: I edited the note as it's not about the country itself. For example, all Belgian currency now uses Eurion, but the Belgian Franc itself won't be in bold because the Euro replaced it before all banknotes were redesigned. I also added a footnote to indicate that a given currency has been replaced. 193.191.221.220 (talk) 08:05, 15 January 2020 (UTC)

message: The use of the word 'recent' in the 'Other banknote detection systems' is meaningless unless the date of the entry is known and even then would be vague. I suggest someone who knows the actual date inserts it.Jerry (talk) 10:50, 5 March 2014 (UTC)
thread_title:  What does 'recent' mean? 

message: : Research shows that the EURion constellation is used for color photocopiers and is likely not used for computer software.
Does "used for" mean "recognized by", or what? —Tamfang (talk) 07:58, 23 May 2014 (UTC)

message: Florida puts this awful thing all over the top and bottom of a birth certificate. Xerox won't even scan/fax it.
Meanwhile, insurance companies can demand a birth certificate copy be faxed to them. In short, you're screwed until you can find obsolete equipment that is still in working order.  — Preceding unsigned comment added by 50.89.71.42 (talk) 03:40, 2 May 2015 (UTC)
