    Zhanfeng card  is also a leader in the smart card industry for many years, in fact, most of the business of smart card industry and IC induction card contact IC card and contactless are composed of IC chip and induction antenna, it is then packaged in a standard PVC card with no exposed parts of the chip and antenna circuit. The read-write process of contactless IC card is made up of IC chip and reader in a certain distance range ( usually 5 to 15 mm ), through the transmission of radio waves to complete the read and write operation of the chip data. Contactless IC card is a passive body, its working principle is : when the reader to read and write operations on the card, the signal sent by the reader is superimposed by two parts component : a part of the power signal, the signal received by the card, with its own L / C resonance, to generate a momentary energy to supply the chip work. The other part is the combination of data signals, command chip to complete the data modification, storage, etc, and return to the reader, complete a read and write operation. 

    IC card will usually use the following chip as the package chip, the chip is as follows : Mifare1S50,
FM11RF08, Mifare1S70; rFID cards, 1442, 4428, 5542, 5528, HID, Mifare UltraLight IC U1; iCODE 2,
Atmel T5557, TK4100, EM4102, EM4100ID, German Kur magnetic stripe cards, etc.
