I need an icon design for my iPhone app.
I will need two versions - 512x512 and 57x57. The smaller one can be resized version of the large one, or can be slightly modified.
The app is a credit card terminal app. Please search "Credit Card Terminal" in iTunes App Store to see other similar apps.
Requirements: It needs to be professional, clean, and high contrast.
Deliverable should be PNG. You don't need to have the shine effect and rounded corners, because iTunes will add it automatically.
