Method and apparatus for determining if user walks away from a self-service checkout terminal during operation thereof

摘要

A method of operating a self-service checkout terminal located in a checkout area of a retail store includes the step of generating a payment-tendered control signal when a user of the self-service checkout terminal tenders payment for a number of items for purchase. The method also includes the step of detecting movement of the user on a movement detection floor mat and generating a walk-away control signal if the user exits the checkout area of the retail store. Moreover, the method includes the step of generating a personnel-request control signal if the walk-away control signal is generated prior to generation of the payment-tendered control signal. A self-service checkout terminal is also disclosed.
