Point of Purchase displays:

A point-of-sale display (POS display) is a specialized form of sales promotion that is found near, on, or next to a checkout counter (the "point of sale"). They are intended to draw the customers' attention to products, which may be new products, or on special offer, and are also used to promote special events, e.g. seasonal or holiday-time sales. POS displays can include shelf edging, dummy packs, display packs, display stands, mobiles, posters, and banners. POS can also refer to systems used to record transactions between the customer and the commerce.
