Τόσο η τεχνολογία επιτήρησης ηλεκτρονικών αντικειμένων (EAS) όσο και η τεχνολογία ετικετών παρακολούθησης με ραδιοσυχνότητες (RFID) χρησιμοποιούνται ευρέως στο λιανεμπόριο και την εφοδιαστική, αλλά εξυπηρετούν ουσιαστικά διαφορετικούς σκοπούς.
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 Ετικέτες RFID 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.
