Abstract: Techniques for displaying promotional information by providing an electronic sign (ES) which displays promotional information, display slogans, bundled pricing, bulk pricing, and other types of information. The ES can be used by retailers to increase sales, provide an alternate technique for advertising and reduce costs. According to one aspect, an EPL computer reads an EPL/ES data file to determine if an entry is associated with an EPL or an ES. The EPL computer then reads a promotional message from a promotional data file. An index in the EPL/ES data file may be used to determine the correct promotional message. The EPL computer transmits a message to the ES which includes a command for the ES to display the promotional message. The ES then displays the promotional message, providing valuable information to customers who are in the process of making purchasing decisions. In one aspect, an ES displays promotional information associated with an offer and is not associated with any particular single item.

Abstract: Systems and methods are disclosed for handling alternate information on electronic price labels. The system uses a price look-up file reader to determine the presence or absence of alternate data in a price look-up file. If alternate data are present for a merchandise item, the price look-up file reader generates an alternate message to be displayed by the electronic price label, in lieu of the item's unit price. The system includes a computer which maintains a first data file containing item identifiers for items associated with electronic price labels, and which determines the presence or absence, in such first data file, of alternate data, to be displayed by an electronic price label in lieu of an item's unit price. If alternate data are present, the system transmits messages to the electronic price labels containing the alternate messages and a command to display the alternate messages in lieu of unit price information.

Abstract: A method of changing a display sequence of an electronic price label which uses two commands to add and remove information from a display sequence. The method includes the steps of formulating a change sequence message including a number of change sequence commands which reference memory registers of the electronic price label, and sending the change sequence message to the electronic price label. An Add command causes the electronic price label to additionally display data in a predetermined memory register. A Remove command causes the electronic price label to stop displaying data in a predetermined memory register. If data accompanies an Add command, the method further determines whether such data will overwrite existing data in the predetermined memory register, and if it will, stores the existing data for later retrieval.

Abstract: A system and method are disclosed for using an enhanced external data interface to display data in electronic price label (EPL) systems. The enhanced external data interface (EDI) responds to various stimuli or requests, such as a store manager or other user logged onto a computer terminal in real time, computer-generated applications and timed file data. The enhanced EDI may receive messages to store first information in, or to read first information already stored in, an EPL data file. The EDI determines whether it is time to update a message displayed by a particular EPL or group thereof for a particular merchandise item. If it is time to update the message, the EDI compares information read from the EPL data file with information about the same merchandise item stored in a message management file.
