Hey Eric,

The image Don posted was one of the four different types of Security Microdots I have scanned. This one is from a RiverCity $1000 chip (see below). This image was also displayed in the Chipology 101 presentation that Professor Knapp and I presented at the Convention in Las Vegas last July. We've created a pdf version of the presentation so that other may have a "color" copy of it. The Link is below. It does require that the person also have the Adobe Acrobat reader to view the file. If the person doesn't have the Adobe Acrobat reader, there is also a link to Adobe's site so they can download the "Free" reader.

The other Microdots have different text, and when printed on the microfilm, appear to have the "screw head" appearance.

Let me know what you think of the presentation. If you have any questions, please ask, and either Michall Knapp or I will try to answer them.

Thanks again!

Dick
