Voice activated credit card
A credit card that will not work unless it hears its owner's voice could become an important weapon in the fight against fraud. The card requires users to give a spoken password that it authenticates using a built-in voice-recognition chip. The idea is to prevent thieves using a stolen card or fraudsters using someone else's credit card details to buy goods online.
A prototype built by engineers at Beepcard in Santa Monica, California, represents the first attempt to pack a microphone, a loudspeaker, a battery and a voice-recognition chip into a standard-sized credit card.
They are not quite there yet: the card is the length and width of an ordinary credit card, but it is still about three times as thick. Alan Sege, Beepcard's CEO, says the company now plans to use smaller chips to slim it down to normal thickness.
