I think a business card slid down the side of my car window and is stuck down there, can I get it out?

When I brought the window back up the card did not come back up, and I am almost positive it is down in the door and did not fall onto the ground.

I’m not going to take apart the door, if that is even a possibility, can I slide something thin down there to try to get it out? Should I bother trying?
