Self-Checkout EAS Tag Detachment via Payment Verification

The patent implements self-checkout kiosks that allow customers to independently scan items, retrieve prices, and complete payments without cashier assistance. The system automatically detects items on conveyor belts using RFID tags and guides customers through the checkout process, eliminating the need for traditional cashier-dependent checkout lines while maintaining security through integrated EAS monitoring.

EAS (Electronic Article Surveillance) tags are pre-attached to merchandise before it reaches the checkout area. The system performs preliminary identification and tracking of items as they are placed on the conveyor belt, enabling automatic detection and payment processing before the customer reaches the payment stage, thereby reducing waiting time while maintaining security oversight.

The patent merges self-checkout functionality with EAS (Electronic Article Surveillance) anti-theft technology into a single integrated system. The self-checkout kiosk incorporates RFID readers, item detection sensors, and EAS tag readers that work together to simultaneously process payments and monitor for potential theft, eliminating the need for separate security systems while maintaining both efficiency and reliability.

The self-checkout kiosk performs multiple functions: it identifies items via RFID tags, retrieves pricing information, processes payments, and monitors for unauthorized removal of goods. The EAS tags serve dual purposes as both payment identifiers and theft deterrents, allowing the system to maintain anti-theft capability while enabling efficient self-service checkout.
