Title:
SMART CARD AND PEAK CURRENT REDUCING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/076291
Kind Code:
A1
Abstract:
A smart card and a peak current reducing method therefor. The smart card comprises: a Bluetooth module (1) and a master control module (7), the Bluetooth module (1) comprising: a radio frequency open unit and a radio frequency close unit. The radio frequency open unit is used for informing the master control module (7) to run by reducing frequency in an interruption way before opening a radio frequency signal; and the radio frequency close unit is used for informing the master control module (7) to run by recovering normal frequency in the interruption way after closing the radio frequency signal. The peak current reducing method comprises the steps: informing the master control module (7) to run by reducing the frequency in the interruption way before the Bluetooth module (1) opens the radio frequency signal; and informing the master control module (7) to run by recovering the normal frequency in the interruption way after the Bluetooth module (1) closes the radio frequency signal. The smart card and the peak current reducing method therefor can perform peak shifting processing on the smart card, and reduce a peak current of the smart card.
