AI Technical Summary
Existing sales data processing systems using wireless tags, such as RFID tags, often incorrectly read information from unintended tags, leading to erroneous detection and registration of items at checkout or when leaving a store, causing inconvenience and confusion.
A point-of-sales data processing device that acquires article identification information from wireless tags, interrogates a server to verify if the item is in stock at the current or affiliated stores, and registers the item only if it is in stock, while updating the server information to reflect the item's new status.
This solution effectively prevents the erroneous registration of unintended items and accurately detects items still in stock at affiliated stores, thereby reducing customer and store inconvenience and improving transaction accuracy.
