We have an online store with a few hundred products, and we'd like to streamline the checkout & payment process.
Currently our payment processor requires the website to be redirected to their site to make the payment, then the user is redirected back to our site for confirmation.
Instead of redirecting our users to the payment processor's site, can we open the payment processor's site in a popup? I think the popup could either be a separate window (though that might be extra complicated), or as a lightbox (possibly using an iframe).
Does Drupal Commerce support this sort of thing, and is it safe to do or not recommended (as a security risk)?
We're using Drupal 7. Our site is a fairly standard online store.
