Imagine you're at a party full of strangers. You're nervous. Who are these people? How do you start a conversation? Fortunately, you've got a thing that sends out energy at tiny chips in everyone's name tag. The chips send back name, job, hobbies, and the time available for meeting-whatever. Making new friends becomes simple.
想象一下，你身处一个周围都是陌生人的聚会。你很紧张，这些人是谁？如何开启对话？还好，每个人的名牌上都有一个微小芯片，可以发出能量。芯片发送回姓名、工作、爱好和可用于会议的时间。结交新朋友变得简单。
This hasn't quite happened in real life. But the world is already experiencing a revolution using RFID technology.
这在现实生活中并没有发生。但是，世界正在经历一场使用RFID技术的革命。
An RFID tag with a tiny chip can be fixed in a product, under your pet's skin, even under your own skin. Passive RFID tags have no energy source - batteries because they do not need it. The energy comes from the reader, a scanning device, that sends out energy (for example, radio waves) that starts up the tag immediately.
带有微小芯片的RFID标签可以固定在产品中，在宠物的皮肤下，甚至在自己的皮肤下。无源RFID标签没有能源——因为不需要电池。能量来自阅读器（一种扫描装置），它发出能量（例如无线电波），立即启动标签。
Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient's medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person) section and pays for the bill with the wave of an arm.
这样的标记携带特定于该对象的信息，并且可以更新数据。RFID技术已经用于识别道路上的每辆汽车或卡车，它可能会出现在您的护照上。医生可以在皮肤下放置一个小芯片，帮助查找和获取患者的病历。在巴黎或纽约的夜总会，同样的芯片可以让你进入VIP区，然后挥动手臂支付账单。
Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler.
我们往回看：10年或12年前，你会听说即将到来的计算机时代。一个例子似乎总是浮出水面：你的冰箱会知道你什么时候需要买更多的牛奶。其概念是，计算机芯片可以放在任何地方，并在智能网络中发送信息，这将使日常生活更加简单。
RFID tags are a small part of this phenomenon. "The world is going to be a loosely coupled set of individual small devices, connected wirelessly," predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers accompanied by how many biscuits.
RFID标签只是这种现象的一小部分。“世界将是一组松散耦合的小型设备，通过无线连接，”J.Reich博士预测道。人权支持者对这种技术的可能性感到紧张。他们说，通过RFID标签跟踪学校的孩子太过分了。我们想象有这样一个世界，一家啤酒公司不仅可以知道你什么时候买了啤酒，还可以知道你是什么时候喝的，以及喝了多少啤酒，吃了多少饼干。
When Marconi invented radio, he thought it would be used for ship-to-shore communication, not for pop music. Who knows how RFID and related technologies will be used in the future. Here's a wild guess: Not for buying milk.
当马可尼发明无线电时，他认为它将用于船与岸上的通信，而不是流行音乐。谁知道未来RFID和相关技术将如何使用。这里有一个大胆的猜测：不是为了买牛奶。
