What is ESL (Electronic Shelf Labels)? How does it work?

If you have read something on e-reader like Kindle, then you are really not familiar with this Epaper technology. So far, the commercial application of electronic paper is mainly in the so-called electronic shelf label (ESL). ESL technology has existed for decades, and its initial adoption was slow. Its main purpose is to accurately and automatically provide sku-level pricing and promotional information. This has always been attractive, but the cost of early ESL is very high, especially when you add the cost of hard-wired power and data infrastructure. . It is very difficult, if not impossible, to prove that this investment is reasonable.

Today’s digital tags use a battery life of up to 5 years, and the tag display is updated through a wireless access point on the ceiling, which can update thousands of tags in a few seconds.



The lifeblood of any e-paper application is data integration. The shelf-edge ESL is a good start. These glorious-looking digital displays are inserted into security brackets at the edge of the shelf, replacing printed price tags. Integrating with retailer’s sku-level pricing data, a cloud-based content management system (CMS) can automatically update regular and promotional pricing according to any imaginable standard: price area, day of the week, time of day, inventory level, and even Sales demand level.
