If only these walls could talk, the saying goes. In the case of the N building near Tachikawa station in Japan they do. In fact the whole building facade has been transformed into a real time dialogue between smart phones and what’s going on inside the store.
All you do is hold your phone up to the walls and the constantly changing QR codes tell you what’s going on inside. You can also browse shop information, make reservations and download coupons.
