Not trying to nit pick, but it looks like those dollar images are pixel-based textures mapped onto curled objects modeled in 3D space in a 3D modeling program. Options to curl graphics like that in CorelDRAW and Adobe Illustrator are pretty limited. It's more do-able in applications like Blender.
Additionally some of the warping effects in 2D vector drawing programs may fall apart with complex, multi-colored objects -the distortion may not stay consistent with all objects in the group, such as what you would have in a credit card logo. Just look at the strange inconsistencies with myront's Visa card examples above.

Why would you want curved credit cards?
I was wondering the same thing. Curved credit cards don't make a lick of visual sense at all. They're flat and not even very flexible. They don't fall through the air in the same manner as dollar bills either. Unfortunately some customers are really really stupid with their requests. Even more anger inducing: once you go to all the trouble producing the thing they want to see they finally realize just how stupid their idea was and then want a different request. That's why the design fee meter has to be running on B.S. like that.
