Radio-frequency identification (RFID) is the use of a wireless non-contact system that uses radio-frequency electromagnetic fields to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking of the system. Some tags require no battery and are powered by the electromagnetic fields used to read them. Others use a local power source and emit radio waves.
