Radio or wireless is a way of transmitting energythrough empty space—that is, instead of using a wire cable. The energyis carried by invisible waves of electricityand magnetism that vibrate through theair at the speed of light. The basic science and the practicaltechnology of wireless communication was developed in . See more
Imagine your mission is to design an anti-shoplifting device usingsome old radio sets you found in the garage. You could build something a bit like aradar (with a combined radio transmitter and . See moreIt's all a bit more complex than I've made it sound so far because there are, in fact, two quite different types of RF tags and they work in a slightly different way.

But instead of sounding an alarm like the doors do, it kicks off a magnetic pulse generator that fries a simple fuse in any stickers near by (it can also demagnetize your credit cards). Once that fuse is blown, the sticker stops responding to the “Anyone out there?” signals.
For example, some retailers attach RFID tags to merchandise, which are only removed after the item is purchased.
