Thought about it and you are right, thank you. I'll show the documentation I gathered to one or two other persons who are involved in getting that item and who might have valuable input, then we'll just send him the chosen reader. My personal pick is the Pocketbook Pro 912, for the simplicity of the interface and the price.
