Hi there,

I would like to create a pdf file with simply graphics similar to the
graphics in the following link.

http://www.nfc-forum.org/events/oulu_spotlight/2009_09_01_Secure_Element_Programming.pdf

For example, Page 34. I would like to descibe the communication between a
card and a reader/writer. Is there any easy-to-use tools to create simple
graphics? I have no experience with photoshop or coreldraw, is any of them an easy-to-use tools for
this task?

Thanks.

Mark

Depends on how complex you need it to get, how much you want to spend and what formats you need.

Page 34 looks like it was done in powerpoint, to be honest.

If you want to create vector graphics like that, inkscape is a good free program, and it's pretty simple to use.

Thank you!
