Using an inline window to accept Credit Card Payments

Will this increase abandonment.

[lgn1]

I am using a one step checkout add-on (technically 2 steps) for Prestashop. Unfortunately, the payment module can only be done as an inline form, instead of a separate page.

When the customer clicks on the checkout, a rounded window appears, on top of the checkout page, asking for the credit card information (much like verified by visa is/was handled).

The customer cannot move the frame, so its not a popup.

My concern is, will the customer think it's a popup with negative consequences, or thinks that the form is not secure, as and inline form does not have it separate lock button.

However, this is becoming more prevalent, especially with hosted payment solutions using inline frames.

Opinions or experiences ?

I hate any kind of apparent popup. For me, it's always a potential security issue.

Would I abandon the transaction? I'm not sure, I've not seen any unfamiliar windows appear when at the checkout.

If the inline form is shown on a secure page it is not quite as bad, but secure inline frame and insecure URL would send me out of there. Most browsers will show warnings for mixed SSL/non-SSL links. The log-in for my credit cards site where I go to pay my bills is shown in a little inset window on a https: page and even that had me clicking all the "More Information" icons when they introduced it.
