Browser applied to POS terminal

Abstract

The embodiment of the invention discloses a browser applied to a POS terminal. The browser comprises an extended module, an interface rendering module, a magnetic card control module, a card number input control module, a password input control module, a script module, a variable engine module and an event dispatching module, wherein the extended module is used for analyzing the self-defined extended attributes; the interface rendering module is used for receiving a rendering request, analyzing a hypertext markup language (HTML5) document and drawing a render tree; the magnetic card control module is used for acquiring the magnetic card information and encrypting the plaintext magnetic track data which corresponds to the magnetic card information; the card number input control module is used for encrypting the input card number data; the password input control module is used for encrypting the input password data and transmitting the encrypted data to a transaction background; the script module is used for analyzing script codes to obtain a script function and executing the script action which corresponds to the script function; the variable engine module is used for binding with interface elements so as to synchronously update the variable and the interface; and the event dispatching module is used for connecting the browser and a low-level module and packing and transmitting the events on the browser interface to the low-level module.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a browser applied to a POS terminal. Background technique [0002] POS (point of sale, point of sale) terminal is a multi-functional terminal, which can be installed in special merchants and acceptance outlets of credit cards to form a network with computers to realize automatic transfer of electronic funds. It has the functions of supporting consumption, pre-authorization , balance inquiry and transfer functions, which are safe, fast and reliable to use. [0003] POS application development, at present, follows the traditional development languages ​​of C / C++ and JAVA at home and abroad. In terms of interface development, the character-based interface development method is basically adopted, even after the color screen is popularized. Only a few vendors use GUI (Graphical User Interface, Graphical User Interface) tools. These old methods cannot achieve good display effects ...
