Problems solved by technology

As a result, the user's password may be stolen by malicious software hidden in the smart operating system, threatening the security of the user's PIN
Even by randomly arranging keyboard numbers and other means, this threat cannot be solved, because in essence, the user’s input coordinate information is obtained by the smart operating system, and the user’s PIN still exists in the smart operating system, resulting in the possibility of the user’s PIN being stolen. risk

Abstract

The invention discloses an intelligent POS terminal capable of safely inputting a PIN code and a method thereof and relates to the POS terminal field. The terminal comprises a touch screen, an application processor and a safe processor. The application processor and the safe processor are connected. The intelligent POS terminal also comprises a touch screen change over switch. The touch screen change over switch comprises a first state and a second state. The safe processor is used for making the touch screen change over switch be switched between the first state and the second state. When the touch screen change over switch is in the first state, the touch screen and the application processor are isolated. When the touch screen change over switch is in the second state, the touch screen and the application processor are connected. In the invention, a user can be guaranteed to safely input PIN code information.

Description

technical field [0001] The invention relates to the field of POS terminals, in particular to an intelligent POS terminal capable of safely inputting a PIN code and a method thereof. Background technique [0002] In modern society, credit card consumption has become popular, and the application of POS (Point Of Sale) terminals is very common, and it can be seen in shopping malls, restaurants, hotels, hospitals and other places. Traditional POS adopts the proprietary operating system of each manufacturer, and users cannot install applications on it at will, which ensures the security of POS. [0003] With the development of POS terminal technology, Android-based (Android is a free and open-source operating system based on Linux, mainly used in mobile devices, such as smart phones and tablet computers, has appeared on the market, developed by Google and open Smart POS with smart operating systems such as mobile phone alliance leadership and development). These smart operating...
