The device is three times the size of a normal credit card, has a 'microphone, a loudspeaker, a battery and a voice-recognition chip' and is intended to help reduce credit card fraud. The owner speaks a password into the card and the card emits an authentication squawk. Bruce Schneier loves the concept of BeepCard's related sound authentication technology.
