Ive just seen an interesting article from the people who warned me about TV detector vans,
http://www.bbc.com/future/story/20150624-the-secret-codes-of-british-banknotesApparently there's a secret code on banknotes that photocopiers and scanners recognise, and print a warning about the legalities of copying banknotes rather than the image of the banknote itself. Now, because the copying of banknotes is illegal, there was no way for me to actually test this as if I were to, I would be breaking the law and as I don't work in parking enforcement, I can't get away with breaking the law so I had to use my imagination instead. Anyway, after hypothetically using my imagination, I imagined that if I were to try to copy a £20 note, which I didn't of course but if I were to, that a perfect colour image of the £20 might appear rather than the
fabled unicorn warning described in the article. Because I have a vivid imagination, I imagined that this might work for both sides.
I do hope that none of you try to scan a banknote as this is considered to be very naughty indeed but I wonder if you have a vivid imagination like mine, what you imagine the results would be if you were to try copying a banknote (which you wouldn't of course as this would be very naughty).
