Electronic shelf tags can also improve product price and other information accuracy while eliminating human errors in traditional paper labelling and pricing. Electronic pricing is easier to operate, more accurate, and allows remote operation. A pricing update is sent to the labels and cash registers at the same time, significantly reducing the risk of error. ESL systems can ensure the overall shelf product information and pricing are in perfect synchronization and consistency with those in the POS systems, contributing to better tailored promotion and advertising campaigns.
