The Non-Contact Mifare smart card consists of Mifare chip, inductive antenna, and then packaged
in a standard PVC card without any exposed part of the chip and antenna circuit. Non-contact
Mifare card read and write process, by the Mifare chip and the reader in a certain distance range
(usually 1-5mm), through the transmission of radio waves to complete the chip data read and write
operations.
Non-contact Mifare card is a passive body, its working principle is: When the reader is to read and
write the card, the reader sends the signal consists of two parts superposition: part of the power
signal, the signal from the card after receiving, resonate with its own L/C, producing a momentary
energy to supply the chip to work. The other part is the combination of data signals, command chip
to complete the data modification, storage, etc., and return to the reader to complete a read and
write operations.
