How can I show the 3D Model only if the Image Target is not moving?

I'm creating a Card Game, I want to show the 3D model over its Image Target but only if the card is not moving and laying over the ground, I don't want the 3D model to be displayed if the card is in the air on the Player's hand. Do you have any Idea, because my idea is detecting if the Image Target is moving or maybe if the Z position is near 0, I don't know, what do you think guys?

Thank you.
