How can a credit card company make any money off me? I have a no-fee card and pay my balance on time
Of course they make money. They double dip in a lot of instances they make 2 - 3% plus $0.30 per transaction from the merchant and then whatever interest you pay on your card. So let's just say in one day you make stops at Starbucks for a $4 Latte, then at Wendy's for lunch for about $8, then you put about $20 worth of gas in your tank, then you stop at Kroger for some $40 groceries and may you pick up some dinner for about $15.  That's 5 transactions at $0.30 which is a $1.50 then at 3%  starbucks is $0.12, Wendy's $0.24, gas is $0.60 then kroger $1.20 then dinner $0.45 so the total that they get is $4.11 multiply this by about  a million people per day that is about $4.1 million per day that they get. That is a nice penny! just from the merchant so you are making them a lot of money by just using it.
