My payment gateway does not fit properly in iphone or droid

Need 2 screens fixed Problem vertical screen- when using a phone to try to pay for something on my website, the bottom portion of the payment gateway is cut off Horizontal screen - more of the payment gateway is visible but still cut off Fix Make payment gateway more user friendly. I would like the payment window to work both vertically and horizontally. With the ability for the user to scroll up and down without loosing any information they already entered.
