If you click on Mario Kart Channel, you'll see a screen with all your friends on StreetPass. If you click on the right section next to StreetPass list (where your Mii face is), you will see how many games you have won on local an online multiplayer, how many coins you have collected, and how many StreetPass hits you have had.
The best thing about the Mario Kart Channel is that you can create your own Grand Prix and send it to your friends via StreetPass.
