Abstract

Provided is an electronic payment terminal product, especially a method and terminal for automatically identifying pluggable audio device. When an audio device is plugged into a terminal, a signal is provided to a micro-programmed control unit (MCU) of the terminal to determine the plug-in state of the audio device and control the terminal to perform powering-on operation 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 to the MCU to determine the pulling-out state of the audio device and control the terminal to perform powering-off operation. The invention can ensure long-term usage of the terminal, and further enhance application compatibility of the mobile payment terminals with various audio devices.

Description

technical field [0001] The invention relates to an electronic payment terminal product, in particular to a terminal for automatically recognizing and plugging audio devices, which can realize automatic plug-and-recognition of terminal-connected audio devices. Background technique [0002] With the rapid development of electronics and computer technology, its application has penetrated into every field of life. Electronic payment products are no exception. Personal portable payment will be a future development direction of electronic payment, which requires payment terminals to be low-power 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 connection identification between the mobile pay...
