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 is the advantage of the new voice card?
A:It recognizes only its owner's spoken password.
B:It doesn't need to work with an on!mne server.
C:It requires less ID information.
D:It has a playback function.

SECTION A MINI-LECTUREDirections: In this section you sill hear a mini-lecture. You will hear the lecture ONCE ONLY. While listening, take notes on the important points. Your notes will not be marked, but you will need them to complete a gap-filling task after the mini-lecture. When the lecture is over, you will be given two minutes to check your notes, and another ten minutes to complete the gap-filling task on ANSWER SHEET ONE. Use the blank sheet for note-taking.听力原文: Good morning, everyone. First about your second assignment. I'd like to remind you that your second assignment should be in by next Fri day. You can either put it in my pigeon hole, or leave it with the Department's secretary. Now, let's get down to the lecture.Today, the lecture is on credit, er, or to be more specific, on credit cards. I'm sure you must have heard of some credit cards, like the VI SA card, which is an internationally used card, or the Great Wall card issued by the Bank of China, In order to give a better understanding, we'll discuss it in some detail.Many businesses, such as department stores, restaurants, hotels and airline companies, use a credit system for selling their products and services. In a credit system, the seller agrees to sell something to the buyer without immediately receiving cash. He receives the goods or ser vices immediately and promises to pay for them later. This buy-now-pay later credit system is quite old.There are two types of credit cards. One type is issued directly by a store to a customer. Many large department stores issue credit cards to their customers. The store credit card can be used to make purchases only at a particular store. For example, if you have a credit card from Store A, then you can only buy things in that store. Other stores would not accept it. The other kind of credit card is issued by a credit company. Credit cards from credit companies can be used to buy things almost anywhere. If you have a major credit card, you can buy airplane tickets, stay at hotels and eat at restaurant with it. Most large credit companies are connected to large banks. So if you want a credit card from a credit company, you generally have to make an application at a bank. After an applicant receives a credit card, he or she can make purchases using thecard.The credit company sends the customer a statement of purchases at the end of each month. Generally the customer has to pay 25--50% of their credit hill every month. The customer pays directly to the credit company and the credit company pays to the store or hotel or restaurant.There are some advantages and some disadvantages to using credit cards. The biggest advantage for the consumer is expressed by the phrase "buy now, pay later". This means that the consumer can purchase what he wants when he wants it. There is no need to save up money in advance. Another advantage of having a credit card is that it protects the owner, ff a credit card is lost or stolen, the owner only has to call the credit company and the credit company will stop the credit card number. No one else can use it. So the owner doesn't have to worry about losing the card. Another advantage of the credit card system is that the consumer receives a record of his or her purchases. Every month the credit customer receives a bill. The bill has a list of all purchases from that month. This makes it easier to remember when and where purchases are made. And another advantage is that credit cards can be used when something unexpected happens. Many kinds of professional people—plumbers, taxidrivers, doctors and dentists—will accept credit cards in an emergency. This is very important if you don't have any cash with you.However, having said all that, using credit cards has one major disadvantage. That is, consumers tend to overspend their money. They spend more than they make. If a consumer buys a lot of th
