Day 4 - Credit Card Payment

Hey there,

I'm a big fan of drag&drop, so on day 4 I designed this screen, that you could see when buying stuff online. On the left side there are your cards, and you have to drag one of them and drop onto the area on the right. Once you do that, the pay button becomes active, and you can buy the items. I'm not sure how users would like it, but it's something that's definitely worth testing, isn't it?

Best, Zsolt
