This may seem a dodgy thread however im asking out of curiostiy and nothing else !!
Just wandered what note readers actually look for on a note. For example how does it determine if its real and what value it is ?
I ask this cos we get a few fakes where i work and i saw a really good one last week (the only difference was the UV £20 wasnt there), all holograms on it were real.
So can a machine tell what is real or fake ? Or would it be possible for someone to put blank pieces of paper into a machine, with only selected markings on it which the machine is looking for- and it may think it is a £20 ??
Sorry just wandered if this could be possible, bearing in mind if it is im sure people are doing it already like !

I'm pretty sure they look for a series of 'disguised' dots or something like that.
There's one of the notes, not sure which, which appears to have a series of very small musical notes on it. The head of these notes are the dots i mentioned.
I did see a worryingly good fake at work recently as well. The only difference was the holographic, vertical bars weren't evenly spaced out. Unlike normal fakes though, the bars appeared white under the uv light - not blue as they usually do. Forgeries are getting better, but in the main most of them are really, really shit.
In the past month at work i have seen the shittest pound coin EVER (it had no gold paint left on it), a horrible, waxy fake fiver, an equally bad, washed out tenner, and a crap fake 20, and the good one i spoke about there.
I'd never have the balls to use such an obvious fake, and i can't believe the stupidity of some of the people who take them!

theres a piece in our local paper about fake £20's flying about near me at the minute, also was in a pub over christmas where someone was getting some heat over 2 x £20 notes he had supposedly handed over the bar, I usually change up 20 coins in pubs when possible and have been keeping an eye out for and fakes.

Re: Notes
I'm pretty sure that Noteys have a facility to 'train' it what to accept and reject. In other words, I think you switch it to 'train' mode and feed a genuine note in. Repeat with the note the other way round. Repeat with the note upside down. Repeat the other way round AND upside down. It is then 'trained' to accept that particular design of note in any of the 4 possible positions/directions and acknowledge it as genuine - presumably it holds the information of the scanned image somehow, so if it can match the image of the note Joe Public inserts with one it has memorised, it can award the correct amount of credit and accept that note.Johnny Boy wrote:Just wandered what note readers actually look for on a note.

I'm basing this assumption on a techie thread I read at the time when the new £20 note went into circulation, so do please excuse me if I'm completely wrong.
