Rfid Tags And The Field Of The Invention Essay

An RFID reader is a network connected device (fixed or mobile) with an antenna that sends power as well as commands to the tags. The RFID reader acts like an access point for RFID tagged items so that the tags' data can be made available to business applications.

The RFID system mainly includes three parts: reader, antenna, and RFID tag, as shown. Because of the uniqueness of the RFID tag, the reader can locate and

Regardless of the frequency, method of communication, or the power supply, the goal of any RFID system is to enable specific data to be transmitted between a portable device and the tag, and then be processed and used accordingly. RFID systems are used for objects which get lost, stolen often, underutilized, or difficult to locate in a timely manner.

As we can see now RFID technology is becoming very popular around the world. However, in my opinion, I would like to say that RFID tags pose a risk to personal privacy. RFID tags easily to be stolen by hackers. They could steal your personal information such as your credit card or your passports. For example, now in some states of the U.S, the government allows the citizen to use RFID passports. However, many citizen still disagree to apply RFID passports because they think it contains many issued such as it is vulnerable to wireless attack by hackers (it can be read up to 30 feet away and copying without permission from the RFID owner). In addition, it is even more dangerous when the RFID passports can contain information that is corresponding to the photo of the RFID tags owner. So just think what will happen if someone hack your passports and what they can do with its information from that RFID passport? Therefore, even RFID tags is becoming popular and can be the next generation technology in the real world, but now, in my opinion, I would like to say that RFID still contains many problem that can harm to personal privacy.

The RFID technology consists of three kinds of tags i.e. active RFID tags, passive RFID tags, and battery

First of all, what are RFID chips, and what are they capable of? In more detail RFID stands for Radio Frequency IDentification, a technology that uses tiny computer chips smaller than a grain of sand to track items at

RFID tags can be read-only; some even have a factory-assigned serial number that it can be used as a key into a database, or read/write, object-specific data can be written on the tag by a system user. Programmable field tags may be written with an electronic product code by the user.

Radio wave technology has been used since the Second World War but the first application of modern RFID technology came in 1983 when Charles A. Walton received the first patent for his ‘Portable radio frequency emitting identifier’ (US Patent Office, 1983). Since Walton’s patent, modern RFID technology has evolved at a startling rate with “approximately 1500 RFID patents issued between 1997 and 2010” (Mehrjerdi, 2010). The impact RFID has had on global commerce has been wide-spread. Many major industries have found ways to implement the technology into their business practices. Examples include but are not limited to: manufacturing, logistics and inventory control, national defense and commercial farming (FDA, 2015).

RFID usage for patient identification is growing steadily! In many countries like US & France, relevant information is captured and made available for a quick knowledge/reading of patient 's medical and personal data.

Radio frequency identification (RFID) technology is used to electronically identify, track, and store information on a tag. Its main components are a tag, reader, and a database. It is used by all levels of government in various well-known areas, such as logistics support for the military and highway tolls. The purpose of this paper is to analyze the use of this technology by the United States Federal government and some of its major agencies, including the Department of Homeland Security, the Department of Defense, the Department of State, and Social Security Administration. There are more institutions within the Federal government that already use or are strongly considering implementing RFID technology, but have not yet done so for a number of reasons, such as lack of funding, privacy or security concerns. The main benefits and threats of this technology will be discussed for the institutions listed.

A passive RFID tag, more commonly used, is one that is not connected to a power source. These tags rely on the electromagnetic field that is generated by specific RFID tag readers to create enough electrical charge to transmit the stored data in radio waves (Venkateswara, 2011).

RFID is the wireless non-contact use of radio-frequency electromagnetic fields to transfer data. The purposes of automatically identifying and tracking tags attached to objects. Since RFID tags can be attached to clothing, possessions, or

The history of RFID can be traced back to the times of World War-II. However, the first practical application of this technology could be found in USA where Mario W. Cardullo received the first patent for an active RFID tag with rewritable memory on 23rd January, 1973.

RFID technology is not only used at gas stations, restaurants, and department but also at

As shown in Fig.2, there are no ASICs (Application Specific Integrated Circuit) or silicon chips inside the tag. Therefore, the tag should be able to response to interrogation impulse and reprocess the signal. The generalized theory of chipless RFID system is that the antenna motivates the reader area and induces currents on the metallic tags and the induced currents re-radiate the scattered fields back to reader. The response will be re-processed in a specific way through the designed structure, which makes tag recognizable. Normally, a chipless RFID tag is energy-efficient and battery-free because it is not necessary to support digital logic processing and maintain radiation. Thus, harvesting energy from the reader
