Detecting multiple playing cards

I want to detect multiple physical playing cards using the camera, but I read someplace that Vuforia has a limitation of how many objects can be detected simultaneously?

In my case there might be up to as many as 30 cards in play at any time, and I need to detect all of them. Is this possible using Vuforia, or is there another approach that might be better?

Thank you

 

"Best Practices for Large Device Databases
Vuforia can support device databases containing up to 1000 images. These images may be contained in a single database, or across multiple databases that are active at runtime.

While there is no restriction on the total number of targets that can active in your app at runtime, there are specific consideration to aware of when using large device databases."
