Questioned document examination involves a great many areas of expertise. Included under questioned document examination are the following disciplines, a few of which I will hit on this this section: handwriting, typewriting, photocopying and computer printers, forgery, paper and inks, writing instruments, computer disks, gambling machinery, stamps (as in the rubber pad kind) and the dating of documents.

Forgery is really very very difficult, and handwriting identification itself is not easy; but it can be done, and, It could be maintained, it can be theorised, taught, and tested.

Sign your name as you would sign a credit card receipt or some other official document. Have several friends do the same. Now trade. Take a few minutes and try to forge each others signatures. Even more difficult, write a paragraph in your natural handwriting, swap those and try to forge them. Finally try to find the forgery.
