Specification :
An electronic Article Surveillance ( EAS) system is an antitheft technology that is proven to protect merchandise against shoplifters. Small security tags, applied to high-the merchandise, alert retailers when shoplifters try to take stolen items through electronic sensors at exit doors. EAS systems provide a good deterrent against casual theft. The occasional shoplifter, not being familiar with these systems and their mode of operation, will either get caught by them, or will refrain from stealing.
