Can I put a magnetic card holder on iPad Smart Case?

Hello there! I am not even close to be a tech savvy type of person, so I apologize if this question might be silly.

I recently got an iPad 10th with its Smart Case. I basically use it for study purposes so I would like to be able to put a card holder on it rather than in my phone (just school/library passes and such) so I was wondering if these type of accessories were even compatible.

For reference I'm interested in a magnetic card holder similar to the one from apple, but from another brand. Same specifications but different color/design.
