It depends on the size of the visiting card; just as an approximative rule of thumb, the ratio between the max distance and the size of the visiting card can be around 10.

For instance, a 10 centimeters card might be detectable and trackable up to 1 meter or so. 

Thanks for quick reply.   i tried with stone picture and i got 5 rating also but it tracks upto ~0.4-0.5 meter after that there is flickering problem.

Width means "width in 3D space" (for instance, use the width in millimeters of your real printed visiting card)

Hi, when you look from a side direction (left or right), do you see the target from a very steep angle ? (i.e. is the target looking quite skewed from your point of view) ?

No, the probelm is coming when i see the target from front side..

Anywhere you like, for instance you could put it in some file sharing server and send me the link...

Hi sunilkm, thanks for the video, it clarifies a lot.

First:

@AlessandroB.. thanx for info..

-But it's requirement of my app that model should be 3-4 time larger than target and to cover the whole model i have to go away approx (0.5 - 0.7 meter). that should be fine with image target of 15cm width. 

Hi, the reason why there is no flickering when looking from the right side could be due to the lighting conditions (e.g. when looking from the left side perhaps the camera is seeing a sharper image, especially if there is some glossiness in the paper);
