According to the news, what makes this credit card different from conventional ones is
A credit card that only works when it hears its owner’s voice has been developed by US scientists. Researchers hope that the device, which comes with a built-in voice recognition chip and microphone, will be a weapon in the battle against credit card fraud. Even if thieves know a card’s password and personal identification number, they will still have to copy the owner’s voice accurately. The trial card was created by scientists at Beecard in California US. The first version is three times as thick as a normal credit card, but researchers believe smaller chips will allow the card to slim down to a more conventional size. The card is apparently the first to put a voice recognition chip, a microphone, speaker and battery into a credit card. To use the card, the owner first presses a button and hears the prompt "Say your password". If the password is correct and spoken by the right person, the card emits an identification signal which is processed by a computer connected to the Internet. Researchers hope to get the card to handle ten transactions per day for two years before its non-replaceable battery runs out.
选项
A、that it can hear the owner’s voice.
B、that it can remember a password.
C、that it can identify the owner’s voice.
D、that it can remember the owner’s PIN.
答案
C
解析
新闻中提到“美国科学家研发了一种只有听到主人的声音才能使用的信用卡”和“使用这种卡时.主人首先按下一个按钮,然后就马上可以听到‘请说出您的密码’。如果密码正确,且说密码的人也正确的话,这个卡就会发出确认身份的信号,由一台连接到互联网的电脑进行处理。”新研发的信用卡和传统信用卡的区别是,能辨识出主人的声音,而不是简单地听到主人的声音。
