问题    A UK supermarket has become the first in the world to let shoppers pay for groceries using just the veins in their fingertips.
   Customers at the Costcutter store, at Brunei 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 (生物特征识别的) 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 to being hacked and can be copied even from finger smears left on phone screens.
   But Sthaler 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.
   Vein scanners are also used as a way of accessing high-security UK police buildings and authorising internal trading at least one major British investment bank.
   The firm is also in discussions with nightclubs, gyms about using the technology to verify membership and even Premier League football clubs to check people have the right access to VIP hospitality areas.
   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 takes 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 the Daily Telegraph: "This makes payments so much easier for customers. They don’t need to carry cash or cards. They don’t need to remember a pin number. You just bring yourself. 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 haemoglobin (血红蛋白). Your vein pattern is secure because it is kept on a database in an encrypted form, as binary 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. "
Making payments with the finger vein scanners in physical stores and submitting payments online______.
选项 A、show the difference in how to link to shoppers’ bank cards
B、choose the same storage location for users’ bank details
C、yield the same better-than-expected results
D、differ in the degree of difficulty in the payment process
答案B
解析 推理判断题。由定位句可知，顾客的银行卡详细信息随后被存人支付服务提供商Worldpay，这与网购时存储银行卡详细信息的方式一样。由上文可知，手指静脉扫描仪是用于超市，即实体店，由此推知，在实体店使用手指静脉扫描仪付款与网上付款选择了相同的方式存储用户的银行卡信息，故答案为B)。A)“说明在如何连接购物者的银行卡方面存在差异”与原文不符，故排除；C)“产生了好于预期的相同结果”，原文未提及，故排除；D)“在支付过程中的难度不同”，原文未提及，故排除。
