What is RFID card?
》The full name of RFID card is radio frequency identification proximity cards. It can be divided into three frequencies: low frequency(125Khz), high frequency(13.56Mhz) and ultra-high frequency(860-960Mhz).

How does rfid card work?
》RFID reader sends a set of fixed frequency electromagnetic waves to RFID card. There is a LC series resonant circuit in the card. Its frequency is the same as that of reader writer. Under the excitation of electromagnetic wave, LC resonant circuit generates resonance, so that there is charge in the capacitor. At the other end of the capacitor, there is an electronic pump with one-way conduction to send the charge in the capacitor to another capacitor. Internal storage, when the accumulated charge reaches 2V, this capacitor can be used as the power supply to provide working voltage for other circuits, to transmit the data in the card or connect the data of the reader writer.

Applications of RFID cards
》It is mainly used in identification, access control, supply chain, inventory tracking, vehicle cost, consumption, school management, safety, production control and asset management.
》RFID cards have adequate security. Because RFID carries the electronic information, and the content of data vias a password to protect, so that its contents can not easily be forged and altered.
