There are times when you want to buy that funky pair of shoes but are broke as hell, or that expensive watch you are eyeing for weeks now but can't buy for you are loose on moolah.
Often there are times when you are so hard-up for bucks that you actually dream of printing a few stacks.
But be prepared for the dreadful consequences. Here are the reasons why you can't copy or scan money even if you want to.
Although this is a common safety feature in bills, its procedure is quite interesting. Security threads can be seen on almost all prominent currencies across the globe. But instead of printing them normally, security thread is embedded on these banknotes as if the paper was made that way.
A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light. Various currencies have different types of watermarks ranging from prominent people, presidents, emblems etc. So unless you sit on one of those tables inside your country's Central Bank, there isn't a chance you could make one of these watermarks.
No, this has got nothing to do with anything astronomy! This is a security symbol present on all major currencies. This enables the copiers or scanners to detect that the paper they are seeing is a banknote. As soon as the Eurion Constellation is identified, the copiers show an error message stating that the photocopy cannot be performed. It's present on the Euro, US Dollar, Swedish Krona, UK Pound and almost all prominent currencies.
Recently, the copiers have started to use a technology called Counterfeit Deterrence System (CDS) which is so secretive and extremely efficient that nobody actually knows how it works except of course the makers. It is although believed that the Eurion Constellation could be a part of it.
Besides not being able to copy or scan banknotes, you also cannot edit them thanks to the built in Counterfeit Deterrence System (CDS) feature of major editing software. Software like Adobe Photoshop can easily recognize the security features in the bill images and would refuse to edit them. Quite astonishingly, such software can do this job even if these features are blacked out or if almost the entire note is blackened!
