  • the present invention generally relates to pricing systems, and more specifically, but not exclusively, concerns a pricing display system adapted to display dynamically priced goods via a graphical user interface.
  • ticker-tape machine One of the first methods for dynamically displaying fluctuating prices of publicly traded commodities was the ticker-tape machine. As technology advanced, these machines were replaced by electronic displays that simulate a moving ticker-tape. Additionally, non-moving displays are known that display fluctuating prices in real time. Some examples of electronic displays include the graphics generated by news networks during the stock market trading day that reflect the prices of publicly traded stocks. These graphics usually simulate a moving ticker-tape along the bottom of a television screen. Another example of such an electronic display is a Light Emitting Diode (LED) display, such as those commonly used at the various market exchanges, and in the lobbies of brokerage firms.

  • a merchant may be able to demand $250 for video card in January, and be forced to "close-out" the same card for $25 in December. It would be desirable to provide a system that dynamically adjusts the price of an item available for purchase to maximize profit, and display the fluctuating price to prospective purchasers in a near real-time fashion.
  • a system for dynamically pricing products available from one or more on-line merchants may send a first price for a product from a processor to a customer device, and may receive a report of sale for the product at the first price from a merchant computer. The system may then determine a second price for the product based at least on the report of sale for the product at the first price, and send the second price to the client customer device. [0008] In a further form, they system dynamically adjusts a plurality of prices for a group of on-line merchants. The system may send a set of prices for a product to a client computer that has a graphical user interface, and display the prices via the graphical user interface.

Abstract

Cette invention concerne un système (100, 102) permettant une tarification dynamique de produits proposés par un ou plusieurs commerçants. Le système (100, 102) envoie un premier prix pour un produit d'un processeur (104) à un dispositif client (108) et reçoit un rapport de vente du produit au premier prix d'un ordinateur fournisseur. Le système détermine ensuite un second prix pour le produit en fonction au moins du rapport de vente du produit au premier prix et envoie le second prix au dispositif client (108).
