Polo Ralph Lauren Corp. is taking impulse shopping one step farther with technology that allows passersby to purchase clothing they see in the windows of one of its New York stores by tapping on the glass.

A projector beams the images onto the window pane from the inside of the shop, while a thin touch foil mounted on the glass powers the touch screen. The store plans to keep the display up through September 10, though if it succeeds in boosting sales or buzz significantly, Polo Ralph Lauren will roll out the window displays to other stores, a spokesman said.

Customers can shop even when the store is closed by clicking on the window glass, the ultimate in shopping convenience.
