Rfid: A Broad OverviewEssay Preview: Rfid: A Broad OverviewReport this essayRFID: A Broad OverviewNetwork and Telecommunications Concepts I/360Ms. Marjorie MarqueDecember 5, 2005RFID: A Broad OverviewIntroductionRadio Frequency Identification is part of the expansive category of automatic identification technologies. Auto-ID technologies include bar codes, optical character readers and others, such as retinal scans. So what is RFID and what can this technology be used for? Radio Frequency IDentification (RFID) is a system consisting of a tag, a reader and any particular form of electronic data processing equipment, such as a computer (see Tag below). The system is fairly simple to operate. Unlike bar codes, which must be close to the scanner for reading, encoded signals from the tag and the reader are wirelessly transmitted through radio waves across greater distances. RFID not only has the advantage of longer read distances, it also has the ability to read through dirt, rain, snow, fog, direct sunlight and non-metallic objects. RFID can be used to identify, track and sort a wide variety of objects.
RFID TagHistoryThis technology has recently had an impact on so many companies that the majority of people would presume the RFID proposals are new. Conversely, research indicates that RFID technology appears to have had its grass roots in World War II. According to the RFID Journal, Germans discovered the radio signals were changed as they were reflected back to the base after bouncing off planes rolling in the air. This method would alert the radar crew on the ground that the plane was friend or foe and, as such, was the first passive RFID system (2005). In 1932, the British invented the IFF transponder under Watson-Watt. It was the first active system to identify friend of foe (IFF). The paper, entitled “Communication by Means of Reflected Power” (Proceedings of the IRE, pp1196-1204, October 1948) by Harry Stockman, is seen as a landmark in the development of RFID technology and has lead to much more exploration.
It was not until the 1960s companies such as Sensormatic, Checkpoint and Knogo, developed electronic article surveillance (EAS) equipment to counter theft. This was a revolutionary endeavor that can still be seen in operation today. The tags were inexpensive to make and provided effective anti-theft measures (Landt, 2001). The next major transformation in the use of the RFID tags occurred in the late 60s, early 70s. Security and safety issues surrounded the use of nuclear materials and compelled the need for further development of the tagging equipment. The Department of Energy asked the Los Alamos Scientific Laboratories (LASL) to develop a system for tracking nuclear materials. Since that time, the system was a proven asset to the economic success of Americas industry but no one realized the extent of the devices capability.
CommercialCommercially, RFID is still in the infancy stage of development. Various applications have spun off from the original applications of RFID such as identification of fleet vehicles, automatic toll collections on highways, access control to secured and monitored areas and even remote keyless entry or smart keys for automobiles, are fairly common. Ranging from proximity cards that unlock doors to immobilizer chips built into many modern car keys, RFID technologies are already broadly deployed worldwide (see below). Tags in items such as clothing can also link an individual to the item and the tag. Amusement parks, hospitals, and schools are putting RFID tags into wristbands to keep track of patrons, patients, and students. Roughly 40 million Americans carry some form of RFID device everyday (Garfinkel, 2004).

They can be attached to or implanted in almost any object, including humans. For example, doctors and nurses can read the patient identification number and use it to retrieve patient records from the hospital database. Currently, most Americans willing accept and are aware of the fact that pet owners and breeders have, for a number of years, used implanted RFIDs for pet identification and recovery. However, on October 13, 2004, after two years of review, the U.S. Food and Drug Administration approved the practice of injecting humans with Applied Digital Solutions VeriChip for medical purposes. Other countries have been implanting the chips in thousands of patients. Furthermore, the chips are being used as a resourceful authentication tool for building or enhancing security and financial transactions. In fact, the Attorney General of Mexico and nearly 200 of his staff have been implanted with VeriChips as part of an effort to control access to secure areas (Weissert, 2004).
SupplyAs mentioned earlier, RFID technology has recently received a lot of press despite having been in existence for over 50 years. This phenomenon resulted from Wal-Mart, the worlds largest retailer, mandating that their top 100 suppliers use RFID technology on all crates and pallets by January of 2005. Furthermore, David Williams went on to state that an additional 200 suppliers and manufacturers were forced to comply by January of 2006 (2005). This will send RFID production to well over 3 billion chips per year from the 300 suppliers. The chips have not been reliable in terms of a variety of uses and users. However, this mandate will invariably standardize and settle the RFID market. More to the point, there are a myriad of benefits to this edict. As progressively more suppliers are forced to do the same, consumers could eventually stop having to physically search for products because all the items in the store would be tracked
The RFID technology used for storage and retrieval of the data in the computer would be used to provide greater security and secure storage.
There is no way around this, since not all devices currently use RFID technology at the time it is used. However, a limited number that now has been used are not included in the standard definition of RFID technology.
I think the most interesting part of this is the fact that this is just a small step in the process of building our own devices to help store and transfer data and to let information come in directly from the machine.
There is a lot more to this than technology, but it’s a much more interesting point to consider, as consumers may also need to purchase a range of more efficient devices. The following section is aimed particularly for those not familiar with the technology that they’ll need to do their own research before making their decision.
How to Buy RFID-Enabled Smart Cards and Tokens.
When purchasing RFID-enabled electronic devices.
An RFID-enabled smart ticket (a ticket in electronic form may be issued by using a card reader within a smart reader by issuing an RFID number) must be issued within a certain period of time before RFID technology is required and may not be issued until thereafter on the date specified in “A” below.
At this time, the user of a smart ticket will not be able to track their purchases on this card while the digital information being sent to the smart ticket holder is still being collected and processed.
There is no requirement that this is a one-shot purchase.
This is for those who want and have experience with the technology and will then use the smart ticket method to obtain payment and a mobile phone payment.
There is no way around this, as both an electronics and an electronic ticketing system can only use a single person to get their RFID-enabled SmartCard.
The RFID method can only provide the service of sending RFID data to the smart ticket holder’s smartphone which is of no use when sending data that can then be stored in the mobile device.
What would happen if you purchased your device over the Internet using QR Code technology? If you purchased your device using a card reader in an electronic form, this could be considered an electronic ticketing system.
There are a number of different approaches to dealing with a person’s phone bill.
There would need to be a phone service provider to sign them up, including bank service in the coming months, including a bank in Canada. There are also companies including Bancor that offer an online option for the sale of cards and chips that can allow card reader to scan and pass your credit card without you having to purchase the card in advance.
They could even offer a free or discounted mobile app such as RFID Passport where if you click a link on their mobile platform a card reader will scan the mobile phone and pass your card.
What you would get from these offers with the cards and chips used for storing.
As this is an online system, a system is designed to be able to handle all of the transactions which can be made on their mobile platform.
There are also ways to store and store more information
The system could also be accessed from mobile devices in a number of ways such as using a mobile home network or using
