    There’s a lot of information technology packed between the leather cheeks of your wallet: cheque cards, credit cards, travel cards, phone cards. The world of finance in particular has come up with numerous devices that have made their way into our back pocket—to make it easier to spend, but, just as important, to keep track. (41)______. Excluding small daily cash deals, there are now more than 1000 transactions per person annually. And for every one a record must be made of the sum, the parties involved and the purpose.
    Plastic money is big business: there are more than 420 million Visa cards alone on the planet, worth something in the region of 700 billion pounds, and the total of plastic transactions is expected to reach 4.8 billion pounds in Britain by the end of the century. Common to all cards is that they are made of PVC (plastic) and have ferromagnetic strip on the back—the same stuff as video tape. (42)______. What is never recorded on the strip is the PIN (personal identification number)—the holder’s secret password for withdrawing money.
    When a card is placed in an ATM, a motorized reader scans the magnetic strip, requests the user’s PIN, checks the balance and, all being well, dispenses the cash. (43)______.
    As today’s technology goes, the magnetic strip that allows all this to happen is pretty primitive: OK for travel cards and season tickets, but not a reliable anti—security measure. (44)______.
    With the introduction of smart cards and electronic money, security will cease to be a problem—at least for a while—and all other cards will be irrelevant. (45)______.

A. If the user enters three wrong PINs, the card is retained and recorded stolen.
B. The wallet of the future may be slimmer, but the data in it will be denser than ever.
C. So, many people like to pay their bills using the smart cards.
D. It can be read by simple scanning machines that can be bought over the counter at electronic stores.
E. The number of financial transactions in the UK has risen enormously in recent years.
F. On the surface of the cards, we can see all kinds of pictures, label of the company, or even some scenic spots.
G. On most strips, information(such’ as the current account number) is encoded by laser on two or three tracks.


选项
