With rfid chips, it is possible to notice things, people or smart card and read the information from a distance. PC Everyone tells you what you should know about the technology that soon are all around you.
You pay by showing key bunch, lock up the Office with the clock and go ahead in the queue by waving his arm. It seems unnatural and strange — or practical and fun? Whatever you think so is rfid technology on the way to break through, and soon abuzz with so called tags on you and your stuff.
In practice, it is a matter of small chips using radio technology sends out the information stored in them. Technology is often explained as a radio-based variant of the bar codes, which are already on the packaging, library books, customer card, driver’s license, and a variety of other places. RFID technology has many more uses. We find them already, for example, access cards and some ski passes.–Car tariffs as soon as introduced in Stockholm based on rfid technology, and smart card for public transport are underway in several cities, says Pär Ström who is a consultant and expert on rfid.
Car duties without queue
To access the data in an rfid chips are needed–instead of a bar code reader–an rfid reader. The difference is that the reader does not need to be in direct contact with or even have free air between themselves and the chipset. It is sufficient, therefore, that you have an rfid-tagged gadget in your pocket, in a bag, or in the windshield of the car in order for the reader to recognize and register it, as long as the distance is not too great. It is usually about One decimetre and a few meters.
In the example of car tariffs means that you run through customs and the reader will record information in your rfid chips without having to stop. Is the chipset eliminates the hassle of valid staffed, card draws and note entries. The queues are shorter.
Hard label soft drinks
The big retail chains expect to save money on more efficient inventory management and, ultimately, lower personnel costs. For you as a customer, it may be an advantage to not have to unpack the goods on a tape, then pack them into bags. It is faster and the queues are shorter. Unfortunately, there are some technical problems:–The Radio waves are disturbed by such as fluid and metal; A can of soda is not at all to read by if the chipset sits directly on the metal, says Pär Ström.
In addition, the chips so far too expensive to make it worthwhile to label cheap consumer goods.
In food shops, it takes ten years before rfid replaces dash codes–if ever. I think it will more quickly, for example in clothing stores, says Pär Ström.
Where will it be in addition to the price, size and maybe laundry marking also an instrument for inventory management and theft protection.
Passports with chips upsets many
If you have your own rfid chips—for example, on a credit card or key ring–linked to the store’s database, it is enough that you approve your purchase with a code. Then charged to your bank account or credit card (which you yourself have notified in advance).
–In the United States, there are here already. Where the customer has a small plastic badge with a rfid chips, for example, sit on your keychain. It keeps you up against a reader, says Pär Ström.
Plastic trays first appeared in petrol stations but now works on such as McDonalds and in several shops.
–Last I heard a figure so had the system six million users.
Another area where rfid technology is already used in security and identification. Already used the technique in inpasserings and locking systems.
So far there is no problem, but many are worried that our personal privacy can be sharply circumscribed in a world where we are constantly carrying rfid tags on us.
The new biometric EU passports, introduced in Sweden as from 1 October this year, for example, should be equipped with rfid tags.Although Pär Ström do not want to exaggerate the danger, he did not think that it is a successful solution.
–Rfid goes after all to remotely read. It’s not easy, but a person who has the correct type of readers, and are close enough, can see who I am. I don’t know who gets information about me through my passport, “he said.
In the United States, which has the same type of pass, the issue has aroused great debate. But here at home, it has been awfully quiet.
“There are, for example, articles that provide tips for you to have the passport in aluminum foil, as the metal stop radio waves, says Pär Ström.
Under the skin
Even more controversial is that when rfid chips surgically inserted into the body. The nightclub, the Baja Beach Club in Barcelona got considerable attention when, in april last year offered their regulars to get a chip in his arm. Chipset comes in a glass capsule, which is about 12 millimeters long and two millimeters in diameter which is inserted into under the skin. Chipped guests get to go ahead in the queue, and the drinks will pay by waving your arm in front of a reader.
In the case of nattlubben, it is easy to think that partypinglorna may blame themselves if they want to operate in chips in the arm. But there are other examples where benefit and personal integrity are pitted against each other on more clearly.
In Italy and the United States experimented with rfid tags that make it easy to access medical information such as age, blood group, medication allergies or chronic illnesses.
In Mexico got 160 police officers and Prosecutor chips implanted in July last year. By extension, it may be necessary for all who live in the kidnap threat. Critics argue that the kidnappers probably quickly learn where to put the knife to remove the tag …
Despite some concerns may be legitimate – and despite the fact that Pär Ström is critical to some applications – think he yet not to worry too much.
– The fear is a bit excessive. But the technology must be handled properly, “he said.
And any chips in the arm as it gets for him – at least not in the foreseeable future.
“I am very skeptical of the idea. Possibly it would be okay for medical purposes. If it becomes plain that people have chips in the body, I see great risks to personal privacy. It would be too easy to read us, and thereby oversee us and would increase the risk that information about what we do fall into the wrong hands, says Pär Ström.
