RFID "Radio Frequency IDentification " in English. Is a technique of automatic data recording in which tiny chips are attached to the tracking of goods or packaging.
RFID is used not only for the identification of objects, but also with a living being tracked with radio waves. With these chips small objects can be found without direct contact, for example, a bag money, a bag.
big business consortiums now replaced the old bar code for these chips, so that almost every object and every person can be tracked without being seen. There is currently no regulation or law in Germany or in the world, with which society could be protected from danger or even the abuse of technology.
How the RFID?
RFID chips are very discreet and have small antennas that have a transponder coded. There is a transponder each microchip, an antenna, magnetic disks, power source. They are distinguished in part much from each other by the different models. Transponder RFID can have a writable memory where information is stored on your location.
There are indicators that distinguish between different chips, for example, radio frequencies distinguish the transfer rate, life expectancy, cost per unit, memory space, scope and extent of harvest functional in some products, but they have attracted attention (eg store card companies). There
RFID - ways. They are carried in the customer cards, credit cards and a price tag where they do not attract attention. Always depends on the job for which they are determined.
These serve as protection from theft and alarm system for buildings. The RFID is used for a long time. Large chain retail as Metro, Rewe, Tesco and Wal-Mart use RFID chips.
Used for:
• animal identification
• The road barrier car journey
• contactless chip cards in Asia are distributed without contact in the new notes rechargeable
• Administration of the existence of goods (the control of books in the library of Stuttgart)
• The vehicle identification: E-Plate fees are automatically identified near reading devices
However, in my opinion there are also disadvantages in RFID chips. The RFID technology risk is the loss of self-determination and management of information.
find that, therefore, is a risky bet because of the imminent arrival of the RFID - Transponder without adequate data protection. Another point is whether the goods contain liquid metal or the transponder may not work, and can not be read. I think there is a problem if several products are on a shelf.
I very interested in this subject, since I myself am a user of RFID chips, how my car key. Since I am also a student, I find it interesting that our student ID cards at the university have these chips.
