EAS (Electronic Article Surveillance) system emerged as the need for retailers to prevent shoplifting increases. Many years of experience have proven that EAS is an effective way to reduce merchandise shrinkage. With the protection of an EAS system, high shrinkage rate products that are originally placed behind the counter or in locked cases for anti-theft reasons can then be displayed on the floor for customers to browse freely without the need to interact with shop assistants, which in turn increases sales. A reduction in merchandise shrinkage and an increase in sales means higher profitability for retailers.
