System and method for promotional display verification in EPL systems

摘要

A system and method are disclosed for verifying displays of alternate or promotional messages in EPL systems. A display verification program determines system date and time, and reads first information from a message management file corresponding to a message that is supposed to be displayed on an EPL during the present time period. The program reads second information from an EPL data file, corresponding to a message that is presently displayed on the EPL. If the two pieces of information are different from one another, the program causes a message to be transmitted to the EPL, containing the information from the message management file and a command to display such information. <IMAGE>
