Looking for an easy tool to make simple graphics

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, is it an easy-to-use tool for
this task?

Thanks.

Mark

 

Photoshop would be expensive overkill for something this straightforward.

Why not try the drawing tools in Word if you have it or the drawing module in
OpenOffice or LibreOffice if you don't. That's what I would use if I had
just a few such diagrams to produce.

Or have a look at open source graphics applications to see if there's
something which looks more suited to your tastes/needs. At least the price
is always right:

they aren't really graphics, its a table with borders so word / excel
or the free versions eg open office would do it
