Radio Frequency Identification (RFID) is a radio technology system consisting of a transmitter and receiver which enables the contactless identification and localization of objects and living beings. In the industrial sector, RFID is often used for access authorization or for location. An RFID system consists of a transponder (which contains the identifying code and is located on or in the object or living being) and a reader for reading out the identifier. The identifier can be read out by a scanner with an RFID reader, for example.
