It's a bitcoin vending machine. Owner of a bar/cafe/shop can accept bitcoins for payments and load them in this machine to convert them to cash. Those who want to spend bitcoins don't need to find those who want to buy them. Shops have easier way to accept and convert bitcoins into local currency => more places to spend bitcoins => more places where to buy bitcoins => more people using bitcoins => value grows => more shop owners are interested in keeping some BTC as an investment => less need for local currency => less friction => more bitcoin adoption => local currencies die out of hyperinflation (aka massive sell off) => fully deflationary economy => we all die in a deflationary spiral (not really ;-)
