The RFID revolution has started and our lives are changing forever! well, for your information, radio Frequency identification has with us since the Second World War, when it was used to identify planes from a distance. Now the united State army uses it to control it tanks in irag.
But RFID isn't only limited to military use. The retail giant Wall-Mart uses it to tracks good from the minute they enter the warehouse to the time the customer takes them home and consumes them.
And it's not only the retailer who can benefit from RFID technology. And we be able to find out all we need to know about a product from the RFID tag on it. We will also be able to do our weekly shop without actually having to enter a supermarket.
It's an electronic label formed by a small atenna and a chip the size of a grain of sand. The great advantage of RFID technology is that the tags can be read from a distance and do not have to be in the visual field of a laser reader.
Other uses of this revolutionary idea run from pet indentification to luggage labelling in airports. But the personal information on the tag poses a threat to security, and there is growing group of opponents to RFID.
