online card tricks

Does anyone know how those online card tricks work? If you haven’t seen one, just go to http://www.magiccardtrick.com Any help would be greatly appreciated.

That's a cute trick, and I kind of hate to spoil it for those who haven't already experienced it by just giving it away. Here's a clue that you can put to use easily enough since you're already familiar with the site: go back through the procedure, but instead of noting one card, note all five.
A friend and I used to do magic back in our teens - many years ago - and when we first saw this gag we were blown away. We showed it to another guy at work who had no such background: he saw through it immediately. On screen as on stage, magic is mostly a matter of direction and misdirection.
