Abstract
A device for matching and identifying an audio interface of a mobile terminal and an electronic signature token are provided. The audio interface of the mobile terminal includes a first pin, a second pin and a third pin, the first pin is one of a microphone pin and a ground pin, the second pin is the other one of the microphone pin and the ground pin. The third pin is connected with the first and second pins via a switching module. When the switching module connects the third pin and the first pin to form a first loop, an impedance of the first loop is matched with an identification resistance of the mobile terminal. When the switching module connects the third pin and the second pin to form a second loop, an impedance of the second loop is matched with the identification resistance of the mobile terminal.
