No, they are all the same size.
The wallet will fit a playing card or business card without modification. They are shaving down the sides so that they can slip the business cards in quickly, otherwise they need to go in perfectly straight and have a tendency to get stuck when you pull them out.
That said if you are careful, you can use normal business cards without an issue.
