Abstract

The invention relates to an electronic payment terminal product, in particular to a method for automatically identifying pluggable audio devices and a terminal. When an audio device is plugged into the terminal, a signal is provided for a micro-programmed control unit (MCU) of the terminal so as to judge a plug state of the audio device and control the terminal to perform powering-on operation of by utilizing internal electrical characteristics of an audio interface of the audio device. When the audio device is pulled out of the terminal, another signal is provided for the MCU so as to judge a pulling-out state of the audio device and control the terminal to perform powering-off operation. The method can ensure long-term usage of the terminal and further strengthens application compatibility of mobile payment terminals to various audio devices.

Description

technical field [0001] The invention relates to an electronic payment terminal product, in particular to a terminal for automatically identifying and plugging audio equipment, which can realize automatic plug-in identification of the terminal connecting to the audio equipment. Background technique [0002] With the rapid development of electronic and computer technology, its application has penetrated into all fields of life. Electronic payment products are no exception. Personal portable payment will be a development direction of electronic payment in the future, which requires payment terminals to be designed with low power consumption and portable. Low power consumption requires that the terminal can effectively save power, and can automatically power on when the mobile payment terminal is connected to the audio device; when the mobile payment terminal is disconnected from the audio device, the terminal can automatically power off. To realize this function, the automatic...
