It's the Waiter's Purse model. The accordion part holds money and cards, and the folded part at the front actually turns into a little open-topped box when you flip up the front to hold coins very securely- plus in a dim room you're looking into a shallow tray for coins, not a deep pit like with so many wallets.
I really like how that one is designed. If only it was half the width, to fit a single-fold bill.

While I was looking around, I found one just like the one you linked to, except it had an LED set up to light the inside of the change area. I couldn't find it when I went back for second look.
