Credit Card Only Works When Spoken to
A credit card that will not work unless it hears its owners voice could become an important weapon in the fight against fraud(欺骗).The card requires users to give a spoken password that it recognizes using a built-in Voice-recognition chip.The idea is to prevent thieves using a stolen card or fraudsters using someone elses credit card details to buy goods online.
A model built by engineers at Beepcard in Santa Monica,California,represents the first attempt to pack a microphone。a loudspeaker,a battery and a voicerecognition 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.The company now plans to make it thinner.
The voice card is based on an earlier Beepcard technology designed to prevent fraud in online transactions This earlier card has no microphone,but has a builtin loudspeaker that it uses tosquawk(发出叫声)a voice ID signal via a computers microphone to an online server.
