RFID is in use all around us. If you have ever chipped your pet with an ID tag, used EZPass through a toll booth, or paid for gas using SpeedPass, you've used RFID. In addition, RFID is increasingly used with biometric technologies for security. Unlike ubiquitous UPC bar-code technology, RFID technology does not require contact or line of sight for communication. RFID data can be read through the human body, clothing and non-metallic materials. Components A basic RFID system consists of three components: An antenna or coil A transceiver (with decoder) A transponder (RF tag) electronically programmed with unique information The antenna emits radio signals to activate the tag and to read and write data to it. Antennas are the conduits between the tag and the transceiver, which controls the system's data acquisition and communication. Antennas are available in a variety of shapes and sizes; they can be built into a door frame to receive tag data from persons or things passing through the door, or mounted on an interstate toll booth to monitor traffic passing by on a freeway. The electromagnetic field produced by an antenna can be constantly present when multiple tags are expected continually. If constant interrogation is not required, the field can be activated by a sensor device. Often the antenna is packaged with the transceiver and decoder to become a reader (a.k.a. interrogator), which can be configured either as a handheld or a fixed-mount device. The reader emits radio waves in ranges of anywhere from one inch to 100 feet or more, depending upon its power output and the radio frequency used. When an RFID tag passes through the electromagnetic zone, it detects the reader's activation signal. The reader decodes the data encoded in the tag's integrated circuit (silicon chip) and the data is passed to the host computer for processing. RFID tags come in a wide variety of shapes and sizes. Animal tracking tags, inserted beneath the skin, can be as small as a pencil lead in diameter and one-half inch in length. Tags can be screw-shaped to identify trees or wooden items, or credit-card shaped for use in access applications. The anti-theft hard plastic tags attached to merchandise in stores are RFID tags. In addition, heavy-duty 5- by 4- by 2-inch rectangular transponders used to track intermodal containers or heavy machinery, trucks, and railroad cars for maintenance and tracking applications are RFID tags. Active or Passive or … RFID tags are categorized as either active or passive.
Radio is device that use technology of using radio waves to transfer information, such as sound, by using the properties of electromagnetic energy waves transmitted through space, such as their phase, amplitude, frequency, or pulse width. If radio waves passing an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be get back into its original form.
For years law enforcement has been searching for more effective less lethal options to apprehend suspects. One of the newest technologies available is the Taser, also known by industry standards as an electronic controlled device (ECD). The Taser uses electricity to override the central nervous system, an effect referred to as “neuro-muscular incapacitation (NMI), to cause temporary incapacitation to allow officers to gain control of a subject.
Since then barcode readers are now called laser scanners. Almost every item that you purchase in a shop has a barcode on the packaging. These look like a series of thick and thin black lines. The barcode contains details about the product. It also contains a check digit, so that the computer can validate that the data has been read in correctly.
Drones use Radio Frequency (RF) transmitters (TX) and receivers (RX) to send the information used to control the drone. Inside the radio, transmitters encode the digital data from the movements of sticks and switches into an electric current, which gets sent through wires to the radio’s antenna. There, the electric currents generate electromagnetic radiation, or radio waves. Waves with different amplitudes (heights) or frequencies (durations) carry different messages. (FM and AM radio stations stand for Frequency Modulation and Amplitude Modulation, respectively.) The radio wave moves through the air at 186,000 miles per second, is picked up by the drone’s receiver and undergoes the same magic in reverse — radio waves turn into electric currents, which are then interpreted by the drone as adjustments to

This year we will reach the two billion passenger landmark, which on current trends will translate into 30 million pieces of mishandled baggage" [6]. The IATA surveyed airlines on their understanding of the reasons for and proportions of bags being mishandled. Among the main reasons, the airlines identified two areas where RFID can fix
Radio-wave technology is one of the most important technologies used by man. It has forever changed the United States and the world, and will continue to do so in the future. Radio has been a communications medium, a recreational device, and many other things to us. When British physicist James Clerk Maxwell published his theory of electromagnetic waves in 1873, he probably never could have envisioned the sorts of things that would come of such a principle. His theory mainly had to do with light waves, but fifteen years later, a German physicist named Heinrich Hertz was able to electrically generate MaxwellÕs ÒraysÓ in his lab. The discovery of these amazing properties, the later invention of a working wireless radio, and the resulting technology have been instrumental to AmericaÕs move into the Information Age. The invention of radio is commonly credited to Guglielmo Marconi, who, starting in 1895, developed the first ÒwirelessÓ radio transmitter and receiver. Working at home with no support from his father, but plenty from his mother, Marconi improved upon the experiments and equipment of Hertz and others working on radio transmission. He created a better radio wave detector or cohere and connected it to an early type of antenna. With the help of his brothers and some of the neighborhood boys he was able to send wireless telegraph messages over short distances. By 1899 he had established a wireless communications link between England and France that had the ability to operate under any weather conditions. He had sent trans-Atlantic messages by late 1901, and later won the Nobel prize for physics in 1909. Radio works in a very complicated way, but hereÕs a more simple explanation than youÕll get from most books: Electromagnetic waves of different wavelengths are produced by the transmitter, and modulations within each wavelength are adjusted to carry ÒencodedÓ information. The receiver, tuned to read the frequency the transmitter is sending on, then takes the encoded information (carried within the wave modulations), and translates it back into the sensory input originally transmitted. Many of the men who pioneered radio had designs for it. Marconi saw it as the best communication system and envisioned instant world-wide communication through the air. David Sarnoff ( later the head of RCA and NBC) had a vision of Òa radio receiver in every homeÓ in 1916, although the real potential of radio wasnÕt realized until after World War I.
The sensor, in this case, can be a camera whereas the marker can be something as simple as a QR code. For example, a QR code sticker can be put on the hood of a car which will allow you to see a virtual hood on the car when you see it through the camera.
The microchip under the skin puts off radio frequencies, which activate when scanned, showing the unique identification number of the animal which can be used to get their owner’s information (“Why Pet Microchips Aren't Always
Radars work by sending out wave frequencies, and then detecting the object once the waves are sent back from the target. The wavelengths are usually microwaves, but the type of wave is not strictly a microwave. The strength of the returning signal helps determine what the object is.
A small Bluetooth chip is inserted into a device, the chip replaces the cables and carries all the information normally carried by cables. Then the device transmits the information at a special frequency to a receiver Bluetooth chip via an antenna (made of copper wiring) attached on to the Bluetooth chip. The wave is produced by the movement of the electrons up and down in the antenna when data is transmitted from the master device. (Freeman, 2001) The Bluetooth chip and its antenna are shown in figure 1.
The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology.
RFID, or radio frequency identification, is the new system that is replacing the use of barcodes. RFID tags allow users to more quickly obtain information from the object that the RFID tag identifies (Evans, 2012, p. 190). RFID tags are more helpful and will eventually replace barcodes entirely because they allow the user to scan the object without physically touching or optically reading anything on it. Rather than reading an identification number that is then looked up in a database, it is possible to gather information directly from the tag (Bonsor).
