What happens if you transfer amount to your credit card with 0 balance?

I had 0 balance in my credit card but I accidentally transfered some money into it, what happens now? What will happen to my money?|||I did that once when I electronically paid the wrong card. It shows up as a credit. As you buy things it will use up that credit before you owe anything.|||You mean you PAID over the due amount? It'll just show as a surplus on your account.
