   The other day, I happened to meet someone I hadn’t seen for many years. I couldn’t believe the change in him. As a matter of fact, he didn’t even seem like the     person.

 When I first knew Bill, back in     , he was one of the most carefree(无忧无虑的) people I had ever      . He was always ready to have a     . He usually went out for beer at three o’clock in the morning or drove 50 miles to see an old      he really liked. Bill and I were in the same class in college, and      was never dull when he was     . With him there was one wild      after another. Sometimes I wonder how we      to study for our exams.

 Last week I was in Houston on business, and I ran into Bill in the bar at the hotel.     , I wasn’t even      it was he. Was this short-haired businessman really the same person? I wasn’t really sure until I came near him, but it indeed was Bill. Now he works for a bank. He      most of the evening about his job, his new car and his house. How he had changed! Back when we were in college, the     thing Bill cared about was possessions. Now they seemed to be his main     . Although I have changed quite a bit myself, somehow, I never      Bill changing so much. My image of him      the one I had formed      the time when we were college students together.

 I suppose it’s      to expect people to remain the same, especially      I have changed so much myself. But I must say that I enjoyed the old Bill much more than the new Bill. Maybe he       the same way about me.

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 get a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting – whatever. Making new friends becomes simple.

This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.

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 (装置), that sends out energy (for example, radio waves) that starts up the tag immediately.

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.

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 he put everywhere and send information in smart network that would make ordinary life simpler.

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.

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.
