The logo shows two shapes indicating that you entered the wrong code. The shape on top is a long rectangle with four small circles in it, such as the diagram you see when you type in a PIN at an ATM. The shape below it is a circle with an X through it, denoting that it is incorrect.
This is a Wrong Pincode icon. It is available in PNG and vector. Downloading is free for PNGs up to 100x100px.
