In principle, an RFID system is the communication between a reading device and a transponder (tag / label) at a defined frequency, such as radio communication.

An RFID system essentially has four functional components: memory element, readers, antennas and control.

The reader is the device that transmits the radio waves in order to decrypt an existing magnetic field. A passive RFID tag generates the energy from its magnetic field. The circuits in the microchip allows the reader to transfer the data to the data carrier.

The controller processes the data decrypted by the reader for further system processes.

The antenna is a coil of copper wire specified to emit RFID signals and allows the chip to transmit information to a reader which also has an antenna.

The TAG (or transponder) is a memory device, usually EEPROM, programmed with a series of bits with an integrated antenna to receive and transmit data.

The basic types of RFID tags can be classified as write and read only. Data stored via the read / write tags can be edited, added, or completely rewritten when the tag is in the range of the reader. Data stored in a read-only tag can be read, but can not be edited in any way. Read / write tags are much more expensive than just read tags
Active tags contain a battery that generates signals that are transmitted to the reader.
