A product dispensing system comprises a point of sale (POS) terminal 16, a barcode scanner 18, and a dispensing machine 10 for selectively dispensing individual product items of different product types in response to a dispense request identifying a particular product type. The dispense request may be generated by pressing a particular key on a keyboard 12' or by scanning a barcode label on a sheet of such labels. A data store stores a plurality of product type IDs and a plurality of related barcode data each associated with a respective product type, and a controller automatically supplies to the POS terminal the barcode data relating to any product item successfully dispensed by the dispensing machine in response to a dispense request. For product items not dispensed from the dispensing machine, the controller supplies the POS terminal with the barcode data scanned by the barcode scanner.
