Whether retail stores install EAS anti-theft systems depends on many factors, including the size of the store, the value of the goods, anti-theft needs, and budget. Here are some considerations for installing EAS anti-theft systems:

1. Anti-theft effect: The EAS anti-theft system can effectively reduce the theft rate in retail stores. According to research, merchants who install EAS anti-theft systems have a 60% to 70% lower theft rate than those who do not. The EAS anti-theft system plays a role in preventing theft by placing labels on the goods and installing EAS anti-theft antennas at the exit. When unpaid goods pass through, an alarm is triggered.
2. Technology type: EAS anti-theft system has many technology types, including AM, RF and EM systems. Each technology has its advantages and disadvantages. For example, the AM anti-theft system has a low false alarm rate and strong anti-interference ability, while the RF anti-theft system is susceptible to environmental interference.
3. Cost and return on investment: A high-quality EAS anti-theft system may cost more, but considering the losses caused by theft, in the long run, the EAS anti-theft system can improve the profitability of retailers and is a security measure worth investing in.
4. Customer experience: The EAS anti-theft system can provide security without interfering with the customer's shopping experience. It avoids the embarrassing situation of "person-to-person" and allows customers to freely choose products while ensuring the safety of the products.
5. Brand reputation: A retailer's reputation may be affected by the loss of merchandise. The EAS anti-theft system helps protect brand reputation and reduce the negative impact caused by theft incidents.
   
6. Technology development trends: With the development of technology, EAS anti-theft systems are also constantly improving, such as the integration of RFID technology, intelligence, cloud computing and data analysis. These innovations can improve the performance and availability of the system.
