Abstract: A system and method for transporting items along a conveyor for a checkout system may include starting a conveyor in a transporting direction upon an item being placed in proximity to a start sensor, transporting the item beyond the start sensor and stopping the conveyor prior to the item reaching an end of the conveyor if a checkout sensor positioned in a checkout area indicates that a user is absent at the checkout area. The system and method may further include transporting the item toward the end of the conveyor if the checkout sensor indicates a user is present at the checkout area, transporting the item toward the second end of the conveyor upon a second item being placed in proximity to the start sensor and stopping the conveyor upon the item being sensed by a stopping sensor.

Abstract: Embodiments of the present invention are directed to systems and methods for conducting purchasing transactions using radio-frequency identification (RFID) of items for purchase. Such systems may include a security scale integral with a security conveyor for weighing one or more items placed thereon, a bagging area, a second conveyor for transporting items from the security conveyor to the bagging area, a lane controller for carrying out a purchasing transaction, payment means for accepting payment for the transaction, an RFID reader for receiving data from RFID tagged items and a database having item information stored therein. The system may write new information onto the tag. The system may utilize tag data for item validation and amending an item profile in a security database.
