An Electronic price tag (ET) is an automated price tag and display system which consists of a digital display screen with updated pricing information that can be individually updated and changed remotely as needed. Electronic price tags are an important component of efficient retail operations, providing businesses with greater control over their product pricing and related information on the store floor and helping to maximize sales and profits.

Electronic price tags provide a variety of advantages over traditional printed labels and paper tags. They are more reliable, as information is only updated when the store is closed and not regularly opened and closed like paper tags are. Electronic price tags also reduce waste and can reduce labor costs associated with changing tags. Finally, they can be easier for customers to understand, as the displays are less cluttered and easier to read.
