What are RFID passive brands?
RFID passive marks are a device for recording electronic information that can be interpreted with devices known as RFID reader. RFID is an abbreviation to identify radio frequencies and RFID brands can be connected or implanted into any object or creation, including humans. RFID reader has access to RFID information remotely from a distance of several yards or meters. RFID passive brands differ from active RFID brands in that they do not have an independent energy source and must be activated by a reader. RFID passive brands are widely used in various business, government and transport applications.
The technology behind the RFID brands was a pioneer of Russian scientist Leon Themin at the age of 40. Later, scientists explored the potential of technology for benign use, such as monitoring and identifying aircraft. This device called a transponder is still used onAircraft in modern times. Progress in technology allowed miniaturization of the device and allowed the creation of RFID passive brands that could be connected to objects such as microchips, stickers or even medical devices that can be surgically implanted.
RFID passive brands include a small amount of computer circuits, antenna for receiving and transmitting information, and sometimes coverage for the protection or insulation of this device. The circuits and antenna can be so small that they are virtually undetectable because the limited functioning of the device does not require power or moving parts. When the RFID reader is used in the brand range, it sends a signal that activates the brand antenna. The antenna then transmits the information contained in the circuits to the RFID reader. The rest of the time is the sleeping brand.
Passive brands RFID has gained widespread use in industry and ruling method management method, replacement of previous methods that requestAdvising time -consuming product data input. Implant RFID chips have long been used in animals, first as monitors of livestock for farms and later to monitor or identify escaped domestic animals. In the 21st century, they are used to identify and pay in public transport, toll roads and even credit card transactions. Different governments and independent businesses used them to identify assets and staff to prevent access to theft and control. Starting 2000 years, they have also been added to various official documents such as passports.
The extensive use of RFID passive brands was not controversial; Privacy advocates defend themselves with RFID brands with personal data that officials or criminals could abuse. Some companies sell devices to block RFID signals, so the marks can only be activated with the knowledge and consent of a person. US Food and Drug Administration (FDA) Approved RFID -implanted RFID chips for humanTí in 2004, while Chip Company companies suggest that they can contain medical records or eliminate the need for cards. Needless to say, it did not fit well with privacy advocates. The FDA acknowledges that the implantation of new technology may exist possible complications, including allergic reactions, interference with medical devices or even cancer.
