Abstract: A two-dimensional bar code is used to identify a traveler's luggage, permitting the luggage to be tracked and, if desired, to be delivered to the traveler's ultimate destination (e.g., a hotel). If the traveler is traveling on an airline, a corresponding two-dimensional bar code is applied to the traveler's boarding pass. A two-dimensional bar code reader is used to read the boarding-pass bar code of each enplaning passenger; comparison of these bar codes with luggage bar-code data permits an alarm to be raised if each item of checked luggage is not matched by an enplaned passenger. The boarding-pass bar code may take the form of an integrated passenger identification code for use by, e.g., rental car companies, hotels, and the like.

Abstract: Inventory item records are affixed to inventory item holders. The inventory item records comprise two-dimensional bar code labels containing encoded item identification information and reordering information for ordering replacement inventory items. The replacement inventory items are labeled with two-dimensional bar-coded information describing the ultimate destination, and packed into a container for shipment to a receiving/distribution center. The destination information is scanned and decoded at the receiving/distribution center to enable proper routing of the replacement inventory items.

Abstract: A flexible merchandise checkout system utilizes a portable two-dimensional bar code scanner/data terminal as part of an auxiliary checkout station for use during times of peak customer traffic, permitting two or more checkers to empty a shopping cart at once for higher throughput. The checkout system includes separable modules for scanning purchased items and for receiving customer payments, respectively. Customer checks tendered in payment may be processed in real time via electronic funds transaction (EFT) orders. Depleted inventory is replaceable using a system wherein replacement inventory items are labeled with two-dimensional bar-coded information describing the ultimate destination, and packed into a container for shipment to a receiving/distribution center, at which the destination information is scanned and decoded to enable proper routing of the replacement inventory items.

Abstract: A portable, stand-alone, desk-top, laser scanning workstation includes a laser scanning head mounted above a support base. Objects bearing bar code symbols to be scanned are passed underneath the head for overhead scanning, or are passed along one side of the head for sideward scanning. The symbols are oriented face-up towards the handler all during their passage through the workstation to facilitate sighting and registration of the symbol with the laser light beam generated by the head. The workstation is self-supporting, is fully portable, can process objects of different sizes, and grants access to objects from either side of the workstation. The workstation is connected to a microprocessor-based microcomputer which is mounted within a desk-top console, as well as to a variety of peripheral devices such as a printer, a keyboard, a communications port, audio-visual annunciators and a data display.
