saving player info

hey guys =)

I was wondering how to save player info in a game automatically. I have a game where a character runs around and can collect coins… and enter new levels…ect. Is there a way to store this information in a file so that when the player returns to the game he starts at the last check point and with the same amount of coins?

cheers,
Matt
