Abstract
A multiple technology data reader, for reading bar code labels and RFID tags. The multiple technology data reader includes a bar code reader and a radio frequency identification (RFID) reader, connected to a host computer via a computer bus, such as a universal serial bus (USB). The bar code reader and the RFID reader communicate with the host computer through logically independent data pipes and device drivers. Compound, composite, or complex interface implementations are possible. A single electronic interface may be configured to allow a single host computer to logically communicate with the bar code and RFID readers as either separate independent readers, or as a single cooperative multiformat label/tag data reader. Thus, the bar code and RFID readers may be operated independently, or powered and operated simultaneously.
