Nov 24, 2016

RFID technology of basic work principle does not complex: label into magnetic field Hou, received interpretation device issued of RF signal, with induced current by get of energy sent out storage in chip in the of products information (PassiveTag, no source label or passive label), or active sent a a frequency of signal (ActiveTag, has source label or active label); interpretation device read information and decoding Hou, sent to central information system for about data processing.

RFID (radio frequency identification) system consists of two parts: a read/write unit and electrical transceiver. Reader antenna emits electromagnetic pulse, the transceiver receives the pulses and send the information you have stored to reader response. In fact, this is a non-contact data to memory read, write, or delete.
