RFID
The abbreviation RFID stands for "radio-frequency identification", i.e. identification by means of electromagnetic waves.
With this technology, objects can be identified automatically and without contact by radio waves. Each RFID system consists of a transponder attached to the object and a reader that reads the code stored in the transponder. In theory, an RFID transponder can be as small as a grain of rice and can even be implanted in humans or animals.
RFID technology is mainly used in the logistics industry. For example, in bottling plants, an RFID connection can accompany the transmission of the transported materials or be used in the garment industry and article surveillance.
