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. If the two pieces of information are different from one another, the EDI causes a message to be transmitted to the EPL, containing the information from the message management file and a command to display such information.
