LOW-POWER CONSUMPTION AND PARALLEL PROCESSING IMPLEMENTATION METHOD FOR HIGH-FREQUENCY WIRELESS SMART CARD

摘要

The present invention discloses a low-power consumption and parallel processing implementation method for a high-frequency wireless smart card, which comprises the following steps of: 1, starting a mobile communication terminal equipped with the high-frequency wireless smart card, resetting the high-frequency wireless smart card, initializing parameters, and configuring parameters of a radio frequency communication module; 2, finishing the initialization of the high-frequency wireless smart card, and setting the high-frequency wireless smart card to enter a working state from a sleep state when the high-frequency wireless smart card receives ISO7816 interrupt or clock interrupt or when the high-frequency wireless smart card receives ISO7816 interrupt or Input/Output (I/O) interrupt; 3, enabling the high-frequency wireless smart card to enter the sleep state, so that the mobile communication terminal is in the most power-saving state; and 4, when an interrupt signal is received, the high-frequency wireless smart card implements processing according to conditions set in the step 2. By the method of the present invention, the high-frequency wireless smart card can transmit data by high-frequency transmission, and the high-frequency wireless smart card implemented by the method has the characteristic of low-power consumption and high card swiping response speed.
