Rod cores RFID

Basically, an RFID system is the communication between a reader and a transponder (tag / label) at a defined frequency as a radio communication.

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

The reading device is the device that transmits the radio waves to decrypt an existing magnetic field. A passive RFID tag generates the energy from its magnetic field. The circuits in the microchip, it allow the reader to transmit the data to the disk.

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

The antenna is designed to emit a coil of copper wire around RFID signals and allows to transfer the chip information to a reader, which also has an antenna.

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

The basic types of RFID tags have the write and read only be classified. Data stored on the read / write tags can, edited, added or completely rewritten, when the day is in the range of the reader is. 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 read-only tags.
Active tags contain a battery that generate signals that are transmitted to the reader.
