Smart card
A smart card includes a main stuff body and a data display module. The main stuff body includes a RF antenna, a charge pump module, a first processing module, and a second processing module. The RF antenna is utilized for receiving a read/write signal and a card data signal. The charge pump module is applied for generating inductive working power by coupling resonance when the RF antenna receives the card data signal. The first processing module is deployed for receiving the read/write signal and transmitting a data signal representing the card data to the reader/writer. The second processing module is utilized for transforming the card data signal into a displaying signal for showing the card data. The data display module is applied for receiving the displaying signal to show the card data by inductive working power and keeps in displaying the card data when inductive working power is gone.
