We’ll go shopping without mobile phones

◆Susan

A UK supermarket has become the first in the world to let shoppers pay for groceries using just the veins(静脉) in their fingertips.Customers at the Costcutter store, at Brunel University in London, can now pay using their unique vein pattern to identify themselves.The firm behind the technology, Sthaler, has said it is in “serious talks” with other major UK supermarkets to adopt hi-tech finger vein scanners at pay points across thousands of stores.

It works by using infrared(红外线) to scan people’s finger veins and then links this unique biometric map to their bank cards.Customers’ bank details are then stored with payment provider Worldpay, in the same way you can store your card details when shopping online.Shoppers can then turn up to the supermarket with nothing on them but their own hands and use it to make payments in just three seconds.

It comes as previous studies have found fingerprint recognition, used widely on mobile phones, is vulnerable(易受攻击的) to being hacked and can be copied even from finger smears(污点) left on phone screens.But Sthaler, the firm behind the technology, claims vein technology is the most secure biometric identification method as it cannot be copied or stolen.Sthaler said dozens of students were already using the system and it expected 3,000 students out of 13,000 to have signed up by November.

The technology uses an infrared light to create a detailed map of the vein pattern in your finger.It requires the person to be alive, meaning in the unlikely event a criminal hacks off someone’s finger, it would not work.Sthaler said it take just one minute to sign up to the system initially and, after that, it takes just seconds to place your finger in a scanner each time you reach the supermarket checkout.

Simon Binns, commercial director of Sthaler, told theDaily Telegraph： “This makes payments so much easier for customers.This is the safest form of biometrics.There are no known incidences where this security has been breached.When you put your finger in the scanner it checks you are alive, it checks for a pulse, and it checks for hemoglobin(血红蛋白).Your vein pattern is secure because it is kept on a database in an encrypted(加密的) form, as binary(二进制) numbers.No card details are stored with the retailer or ourselves, it is held with Worldpay, in the same way it is when you buy online.”

2.D。推理判断题。根据文章第一段和第二段的第一句话中“unique”一词可以知道D正确。

3.D。主旨大意题。连词But之后的内容是作者强调的重点，故D正确。

4.B。细节理解题。根据第三段第二句话和第四段第二句话可以知道①②③符合题意。

5.D。细节理解题。文章最后一段Simon Binns的话可以看到各选项内容，只有D不符合文中句意。

长难句分析

1.The firm behind the technology, Sthaler, has said it is in “serious talks” with other major UK supermarkets to adopt hi-tech finger vein scanners at pay points across thousands of stores.

发明这项技术的公司Sthaler表示，他们正在和英国其他主要超市“认真沟通”，让数千家商店的收银处采用高科技指尖静脉扫描仪。

这是个复合句。宾语从句中serious有“认真的”之意。宾语从句中的不定式是目的状语。

2.It requires the person to be alive, meaning in the unlikely event a criminal hacks off someone’s finger, it would not work.支付者必须是活人，这意味着一旦犯罪分子切下某人的手指，那也是行不通的。

这是个复合句。句中meaning及其后面的内容是分词做状语，“it would not work”是虚拟语气。例如：If I were in Beijing now, I would visit the Forbidden City.如果我现在在北京，我就去参观紫禁城了。
