RFID (Radio Frequency IDentification, Radio Frequency Identification) is a method of automatically identifying objects, which means that data stored in so-called transponders or RFID tags are read or written using radio signals. Any RFID system consists of a reader (reader, reader or interrogator) and a transponder (also known as an RFID tag, sometimes the term RFID tag is also used).
Most RFID tags consist of two parts. The first is an integrated circuit (IC) for storing and processing information, modulating and demodulating a radio frequency (RF) signal and some other functions. The second is an antenna for receiving and transmitting a signal. Already known RFID applications (contactless smart cards in access control systems and in payment systems) gain additional popularity with the development of Internet services.

The Japanese company NEC has developed a lightweight, flexible battery (see photo), which is less than a millimeter thick and can be charged in half a minute.
The novelty is called "Organic Based Battery" (Organic Radical Battery, ORB) and contains a certain type of plastic that exists in the form of a gel. This gel allows the battery to be extremely flexible, with a thickness of only 300 microns.

An ORB can be embedded in devices such as smart cards, laptop computers, and smart paper. In addition, the absence of harmful chemical compounds in the battery makes it environmentally friendly.

Miniature radio frequency identification tags (Radio-Frequency Identification Tags, RFID), long used to track the movement of supplies and stocks, in recent times have become increasingly used for labeling consumer goods. Advocates of private information claim that the devices pose a threat to those who "carry" them, often unaware of it.

Americans living in states bordering on Canada or Mexico already receive a driver's license that can be read remotely. For the introduction of such documents designed to identify US citizens crossing the border of the country, advocate the Department of Homeland Security. But those who are concerned about the security and integrity of the personal sphere should think twice before receiving such an identifier.


The average consumer may not suspect how many RFID tags he has with him. They are integrated into personal items and even into some garments.
