The system is composed of kiosks placed outside the store, which stock up to 25 books and allows customers to browse a touch-screen interface, which gives information on the available titles.
Users can then choose to purchase a book with a credit card without having to enter the store.
Thus the terminals can facilitate sales when the stores are closed, or potentially be placed in remote locations. The testing of the system was conducted in several airports and was reported to be very popular. San Francisco-based Zoom Systems with WH Smith USA Travel Retail developed the concept.
