An integrated, hand-held device combining optical bar-code reading means with RFID-transponder commissioning means includes an on-board processing means, such as a portable-data-terminal that releasably couples to the device and wireless communicates with a host or network computer and seamlessly integrates data communication to and from the optical reader means and the commissioning means. A rechargeable battery pack provides power to each component and a single trigger mechanism enables multi-modal operation based on sensed conditions. Blank or pre-encoded RFID-transponders are supplied by a replaceable cartridge.
