APPARATUS FOR, AND METHOD OF, ELECTRO-OPTICALLY READING TARGETS BY ENABLING A CUSTOMER TO MOVE A CUSTOMER-OPERATED ACCESSORY READER SUPPORTED BY A CLERK-OPERATED WORKSTATION OF A CHECKOUT SYSTEM

A checkout system includes a clerk-operated, bi-optical workstation through which products associated with targets having target data to be electro-optically captured are passed, and a customer-operated, accessory reader having an accessory window and a data capture assembly for capturing additional target data of additional targets associated with transaction-related items. The accessory reader is supported by the workstation for movement relative to the workstation to enable the customer to readily position and aim the accessory window at the additional targets.
