I had an idea to solve the bad lighting condition that is not possible for normal card (unless properly lit). The idea was using a backlit screen device ala mobile phone device or smart phone or even LCD computer screen that could possibly be used to show the AR code.

I try this using my K800 mobile phone with screen size of 320 x 240. It is actually sufficient to show a mini size 3D AR object.

Probably using a large projection of the code is a good alternative, at least for now with this demo software available at hand.

Next step, I will try to somewhat make the 3D AR object to move in animation!
