BROWSER APPLIED IN POS TERMINAL

摘要

An embodiment of the present invention discloses a browser applied in a POS terminal, the browser includes an extension module configured to parse a custom extended attribute; an interface rendering module configured to receive a rendering request, parse a Hypertext Markup Language HTML5 document and draw a rendering tree; a magnetic card widget module configured to obtain magnetic card information, encrypt plaintext magnetic track data corresponding to the magnetic card information and transmit encrypted data to a transaction background for business logic; a card number input widget module configured to encrypt input card number data and transmit encrypted data to the transaction background for business logic; a cipher input widget module configured to encrypt input cipher data and transmit encrypted data to the transaction background form business logic; a script module configured to parse script codes to obtain script functions, and execute script actions corresponding to the script functions; a variable engine module configured to be bound with an interface element so as to achieve synchronous update of the variable and the interface; an event distribution module configured to link the browser with an underlying module, package events of an interface of the browser, and transmit packaged events to the underlying module.
