Both Electronic Article Surveillance (EAS) and Radio Frequency Identification (RFID) tag technologies are widely used in retail and logistics, but they serve fundamentally different purposes.
EAS systems are primarily designed for theft prevention, triggering alarms when tagged items pass through exit gates without being deactivated. In contrast, RFID (radio frequency identification) enables the wireless identification, tracking, and exchange of data for individual items across supply chains.
Technical analyses further demonstrate that RFID tags contain microchips that can store unique identifiers and transmit detailed product data, whereas EAS tags usually only indicate the presence or absence of a tag without providing any item-level information. Consequently, RFID is revolutionising inventory management and retail analytics, while EAS remains a cost-effective anti-theft solution.
Introduction: Why This Comparison Matters
