Card swiping method and device for determining mobile terminal for swiping card, utilizing intensity of ultrasonic signal

Abstract

The present invention relates to a card swiping method for determining card swiping of a mobile terminal by using ultrasonic signal strength, comprising: closely contacting, by a mobile terminal, a card reading device, wherein a multi-interface integrated circuit module in the mobile terminal receives a ultrasonic signal transmitted by an ultrasonic wave transmitting module in the card reading device; measuring, by the multi-interface integrated circuit module, strength of the received ultrasonic signal, and comparing the measured strength with an ultrasonic signal strength threshold which allows card swiping; and if the strength of the received ultrasonic signal received by the multi-interface integrated circuit module is greater than the ultrasonic signal strength which allows card swiping, interactively performing card swiping procedures by the multi-interface integrated circuit module and the card reading device.
