The basic principle of IC card operation is: the RF reader sends a set of fixed frequency electromagnetic waves to the IC card, and there is an LC series resonant circuit in the card, whose frequency is the same as that emitted by the reader, so that under the electromagnetic wave excitation, the LC resonant circuit resonates, so that there is a charge in the capacitor;
ic card is the meaning of integrated circuit card,ic card is a plastic card containing large-scale integrated circuits, its size and the size of the original magnetic card telephone magnetic card. ic cards can often be divided into memory cards, encryption cards and smart cards
