A month ago we got our new Canadian 20$. I just get my first some days ago. I was just checking it since then. This is a really beautiful piece of work. Many flashy features and probably one of the securest money on earth. While checking it, I had an interrogation by remembering what some peoples say about it. Check out his accessibility features. One of them consists of a series of symbols formed by raised dots separated by a smooth surface to help blind people. The problem is that many people think that this is a security feature.

To understand the treat you need to have in mind that people will usually rely on only one simple security feature to discover if the bank note is a real one or a counterfeit. It’s normal that they’ll not check every security measures. If they think that the raised dots is a security feature of the bank note, and also think that this is a simple feature to check, he’ll rely on it to discover the validity of the note.

The problem is that this feature is really easy to forge; anybody can do it. So, if you counterfeit money, add this ‘security feature’ and give it to seller that rely on this feature; you’ll be able to pass it for real money and your goal will be reached.

Another inconvenient is that these dots will eventually disappear. If you have a legitimate 20$ with erased dots and that the seller think that this is a false one because the dots are not present then you’ll have some inconvenience because he’ll not accept it as legitimate and he’ll possibly call the police.

Finally, another time, the only way to erase the treat is by educating people specially them who manipulate a great load of money in their work.
