An electronic business card is provided with voice data associated with the card owner. In some embodiments, the voice data is a digitized voice sample; in other embodiments, the voice data is a selection of pre-processed voice recognition data associated with a voice sample. In some implementations, the electronic business card can be transferred to other parties using a Bluetooth personal network. A user application can then make use of the voice sample or pre-processed voice recognition data for security or user identification.
