Credit Card Only Works When Spoken To

A credit card that will not work unless it hears its owner's 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 else's 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 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.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 built-in loudspeaker
that it uses to " squawk"（发出叫声）a voice ID signal via a computer's microphone to an
online server.
By verifying（证实）that the signal matches the card details,the server can establish
that the user is not simply keying in a credit card number but actually has the card to hand.
The ID code changes each time the card is used in a pre-ordered sequence that only the server knows.
This prevents fraudsters recording the beeps, noting the card details and then playing
back the audible ID when they key in the details later.But this earlier technology cannot
prevent fraudulent use of stolen cards.The new one can.
The new voice card also identifies itself by its ID squawk,but it will not do this until it
has verified the legitimate（合法的）user's spoken password. Thieves will be unable to use
the card because even if they knew the password they would have to be able to copy the
owner's voice with a high degree of accuracy.
The challenge for Beepcard has been to develop voice-recognition and audio circuitry
that can be powered by a mini battery embedded（嵌入的）in a credit card. To maximize
battery life,the electronics are only switched on when the card is being used.Pressing a
button on the card's surface prompts it to utter "Say your password" in female voice.If the
voice-recognition software proves that the password is authentic（真实的）,it sends its ID
squawk which the server then identifies,allowing the transaction to proceed.

What can we learn from the last paragraph about the voice card?
A:Only female voice passwords could be recognized.
B:Further improvement should be made to extend battery life.
C:There is no!imit to its application.
D:Female customers like to use it.

The iPad

1 The iPad is a tablet computer（平板电脑）designed and developed by Apple. It is particularly mar-
keted as a platform for audio and visual media such as books , periodicals（期刊）, movies , music , and games,
as well as web content. At about 1.5 pounds(680 grams),its size and weight are between those of most con-
temporary smartphones and laptop computers.Apple released the iPad in April 2010,and sold 3 million of the
devices in 80 days.
2 The iPad runs the same operating system as iPod Touch and iPhone.It can run its own applications
as well as ones developed for iPhone.Without modification,it will only run programs approved by Apple and
distributed via its online store.
3 Like iPhone and iPod Touch,the iPad is controlled by a multitouch display一a break from most pre-
vious tablet computers , which uses a pressure-triggered stylus（触控笔）.The iPad uses a Wi-Fi data connec-
tion to browse（浏览）the Internet , load and stream media, and install software. Some models also have a 3 G
wireless data connection which can connect to GSM 3 G data networks.The device is managed and synchro-
nized（同步）by iTunes on a personal computer via USB cable.
4 An iPad has different features and applications one can use to execute different and interesting
things.There are lots of iPad applications that the owner can use to enhance the way they communicate.Some
of these are how to use social networking sites and other online options.One of the most common uses is for
e-mail services.iPad applications like Markdown Mail allow the adoption of specific and particular options.
They enable the owner to personalize their email accounts.
5 While the iPad is mostly used by consumers it also has been taken up by business users.Some com-
panies are adopting iPads in their business offices by distributing or making available iPads to employees.
Examples of uses in the workplace include lawyers responding to clients,medical professionals accessing
health records during patient exams,and managers approving employee requests.A survey by Frost&Sulli-
van shows that iPad usage in workplaces is linked to the goals of increased employee productivity,reduced
paperwork,and increased revenue.

iPad applications enable the owner's email accounts to be______________.
A:modified
B:increased
C:personalized
D:browsed
E:distributed
F: released
