What are the New Uses of RFID Chips?


 New Uses of RFID Chip

The outbreak of Avian flu in 2005 left the world full of fear and talk about the color change of avian. Recently, the American company Digital Angel has used its RFID (radio frequency identification technology) products to improve the ability of humans to prevent bird flu.

Biological body temperature detection RFID chip

The company announced that its "biological body temperature detection RFID chip" and its corresponding identification system will be available on the market, mainly serving the global bird market. The initial key service area is Asia, where the "bird flu" is the most serious.


This widely used identification system consists of a temperature sensor chip that can be implanted into the body, and a corresponding identification and temperature scanner, which can identify abnormal increases in poultry body temperature. This makes it possible to quickly identify and control outbreaks of avian influenza, or to control outbreaks of other bird diseases.

So far, "Digital Angel" has been committed to promoting the use of this RFID chip in the pet market and the horse market.

The application of disease prevention in other livestock, such as cattle and pigs, is still in the experimental stage.

Latest Use of RFID chips

Kevin McGrath, president of "Digital Angel", said: "Disease and bioterrorism are posing an increasing threat to the safety of the global food supply chain and the health of livestock and humans. The system targets these new applications. "

As early as in the 1980s, "Father of Cyberpunk" William Gibson had fabricated a sensor chip that could be implanted in the human body in his novel "The Nerve Wanderer". Of course, this chip can not only monitor body temperature, but also include all the feelings of the entire body:


He slammed the simulated stimulation control panel and turned her consciousness. Keith really wanted to laugh. He could feel the microporous tape on her chest and the small devices under the tape: radio transmitters, analog stimulation devices, and encryptors. The throat microphone sticks to the neck and looks like a painkiller.

The hands in the pockets of the pink raincoat kept stretching and relaxing. He only reacted after a few seconds. This strange feeling was caused by the extension and retraction of the blades.

What is an RFID chip?

What is RFID RFID? RFID is the abbreviation of RadioFrequencyIdentification, that is, radio frequency identification e799bee5baa6e78988e69d8331333433623764, commonly known as electronic tags.

What is RFID technology? RFID radio frequency identification is a non-contact automatic identification technology. It uses radio frequency signals to automatically identify target objects and obtain relevant data. The identification work does not require human intervention and can work in various harsh environments.

RFID technology can identify high-speed moving objects and can identify multiple tags at the same time, and the operation is quick and convenient.

RFID is a simple wireless system with only two basic devices. The system is used to control, detect and track objects. The system consists of an interrogator (or reader) and many transponders (or tags).

RFID classification RFID is divided into low frequency (LF), high frequency (HF), ultra high frequency (UHF), microwave (MW) according to different application frequencies, the corresponding representative frequencies are: 

Low frequency below 135KHz, high frequency 13.56 MHz, UHF 860M - 960MHz, microwave 2.4G, 5.8G RFID is divided into passive RFID, active RFID, and semi-active RFID according to the way of energy supply.

Passive RFID has a short read and write distance and low price. Active RFID can provide a longer read and write distance, but requires battery power supply, and the cost is higher. It is suitable for remote read and write applications.


What are the basic components of RFID?

Tag: composed of coupling elements and chips, each tag has a unique electronic code, attached to the object to identify the target object.

Reader (Reader): a device that reads (and sometimes writes) tag information, can Designed as a hand-held or fixed type.

Antenna: transfer radio frequency signals between the tag and the reader.

What is the basic working principle of RFID technology?

The basic working principle of RFID technology is not complicated: after the tag enters the magnetic field, it receives the radio frequency signal sent by the reader.

The bar code patent was issued in 1952, and since then it has been widely used, especially in grocery stores and department stores.

Most of us have not noticed that bar codes existed as early as the 1950s, so it is generally considered to be a new technology. Now with a new technology, RFID tags, barcodes are about to withdraw from the stage of history. RFID chips have become an important part of our daily lives, believe it or not.

This is because humans are always eager to adopt better and more advanced technologies. RFID technology was invented in 1969 and patented in 1973. RFID tags are actually microchips. The RFID chip is a transponder, or what we call a transmitter / transponder.

 It is always ready to receive wireless signals transmitted by transceivers or RFID readers. 

After receiving the specific wireless signal, the RFID chip will respond and send back its unique ID code to the e799bee5baa6e997aee7ad94e78988e69d8331333332636339 transmitter.

Most RFID chips do not have their own batteries, and always start working after the wireless signal wakes them up and requests an answer. Compared with bar codes, RFID chips have many advantages.

There are no restrictions on how to place RFID chips. The only requirement of the RFID chip is that it must be placed within the coverage of the reader and cannot be separated by water or metal. The RFID chip has a read-write protection function, and the data stored in the RFID tag can only be read or modified by authorized users.

RFID chips can be divided into 2 categories, namely, chips using passive technology and chips using active technology.

In the early days, the production cost of RFID chips was very high, but relevant experts predicted that their prices would be lowered sooner or later. RFID chips can be used for most items, even for living things on earth.

 RFID chips are commonly used in the security field, such as attaching luggage and items at airports to reduce luggage loss and simplify the tracking of luggage in the event of any technical failure.

When the customer's flight plan changes, the RFID chip can also help the staff to modify the luggage transportation itinerary. 

Several well-known manufacturers and retailers currently use RFID chips to manage the supply chain process from production to shipment, and then to the placement of goods on store shelves.

For example, RetailGiant, one of the largest employers in the United States, uses "smart shelves" to automatically remind managers and staff to replenish items on the shelves.

Large supermarkets such as Wal-Mart hope that all suppliers will support RFID tracking so that they can point the RFID reader at any sealed cargo box without having to open each box or use a barcode scanner.

In addition, major banks are also trying to issue new Visa cards, combining the advantages of smart cards and RFID chips to easily complete transactions without any cash or coins.

These smart cards can also be installed in mobile phones or other electronic devices to help users pay parking fees or purchase goods without having to pay for their wallets.

Using RFID chips to track assets can reduce the loss or misplacement of assets and improve the security of these items.

The use of RFID chips can improve the security of sensitive items and can be used as an additional verification method.
