Hello,
I'm a web designer and I have to say that I'm incredibly impressed with the whole site. It is polished to an absolute fine level throughout, but the real icing on the cake is the card verification window. Wow, just wow. Real thought has been given to this to create an amicable experience, and I've never seen this so well executed on any other site. You should win an award for it.
For those who are uncertain of what I'm referring to; a screenshot is attached.
Kind regards

The pop up is universal, but the content changes. You're lucky your bank is great, because mine has a really awful content :)

True, the content is provided by the bank, but most websites just redirect to it rather bluntly without any thought of integration. The extra thought to provide it better integrated with the site is wonderful and the first good example I've seen!

I would personally have preferred a real popup, or just a link to the page. The way it's done here causes the whole page grey out and freeze up if the iframe is not automatically loaded, and having "secure" transations occur in a foreign frame foils most anti-fraud system and causes headaches for those who want to verify the source of the content.
