A big Smartphone-like (e.g. iPhone) stand with several "app"-cards (either in the shape of a smartphone or in the shape of an app-icon) for the different books hanging on it. It may even have an additional touchscreen to order additional items from the shop of the bookstore (see image). If customers wants some more information they may attach their smartphone for using the NFC-chip (integrated in the card) or something like QR-, bar-code.
