The most basic RFID system consists of three parts: electronic tags (Tag), reader (Reader) and antenna (Antenna):
Electronic tags (Tag): by the coupling components and chips, each tag has a unique electronic code, that is, ID number. Attached to the object to identify the target object; when the electronic tag into the radio frequency signal generated by the reader antenna area (electromagnetic field), to obtain energy, and then to the reader to send the stored information and data. Sometimes also called radio frequency card, transponder
Reader (Reader): sometimes also known as the query, the communicator or known as the readout device, used to produce transmit radio frequency signal and receive by the electronic label reflected back by the radio frequency signal, that is, the electronic label data, after processing to obtain the electronic label data information. At the same time, also can through the reader to the electronic label inside write user data information. The reader can be designed as handheld or fixed.
Antenna (Antenna): In the electronic label and reader to pass between the radio frequency signal.
