RFID how does it work? Definition of RFID
Are you wondering what the RFID abbreviation means? The name comes from the English language and its extension is Radio Frequency Identification. The RFID system is a modern technology that uses radio waves to wirelessly identify any object. It is a standard for short-range and high-frequency radio communication - it allows for wireless data exchange at a distance of up to about 20 centimeters. An example of the use of RFID can be found in every field of business - including logistics, trade and distribution, construction and the IT industry.
