Abstract: A method, an apparatus, and a system for testing a terminal. The method includes: receiving a smart card switching instruction; acquiring a card channel identifier from the smart card switching instruction; switching a connected-card channel to a target card channel corresponding to the card channel identifier when the target card channel corresponding to the card channel identifier is a contactless card channel; receiving a data request for a terminal test; acquiring, through a first relay repeater, response data in response to the data request, from a smart card to be tested within the target card channel; and sending, through a second relay repeater, the response data to the terminal whereby accomplishing the terminal test.

Abstract: The present application relates to the technical field of HTML5, and provides a method and a system for protecting security of a HTML5 file, and a terminal device. The embodiment of the present application monitors the operations on the HTML5 resource read-only protection zone by pre-establishing the HTML5 resource read-only protection zone, only allows the system authority process to perform read and write operations on the HTML5 resource read-only protection zone, and writes the data of the local HTML5 resource package into the HTML5 resource read-only protection zone to install HTML5 applications, restricting the HTML5 applications from accessing data in the non-HTML5 resource read-only protection zone, such that the non-system authority processes, including HTML5 applications, to only read the HTML5 resource read-only protection zone, and the system authority process is protected by firmware.

Abstract: Embodiments of the invention disclose a data transmitting method, a server and a client.

Abstract: A method of running an application program across systems is proposed, the method comprises loading a target application program; applying for a memory space on a current operating system for the target application program; modifying an address of a global variable and an address of an absolute jump instruction in the target application program according to an address of the applied memory space to adapt to the memory space of the current operating system; obtaining a SWI instruction of the target application program; and redirecting the SWI instruction to an instruction of calling the current operating system.

Abstract: An embodiment of the present invention provides a point of sale (POS) application development method and a cloud server, which are configured to realize development and deployment of an application through the cloud server so as to shorten the development cycle of the POS application. The method of the embodiment of the present invention includes: by a cloud server, receiving and saving application project data transmitted from a web client; by the cloud server, processing the application project data and obtaining an application package; by the cloud server, performing signature processing for the application package and obtaining a signed application package; by the cloud server, transmitting the signed application package to a POS so that the POS realizes an corresponding application based on the signed application package. Another embodiment of the present invention further provides a cloud server.

Abstract: A method of operating a functional module across platforms is proposed, the method includes: obtaining a source code of the functional module, the source code of the functional module being a standard C code; compiling the source code to generate a plurality of intermediate files; link processing the plurality of intermediate files to generate an object file; loading the object file; and allocating a memory space for a bytecode in the object file and dividing the bytecode into a code segment and a data segment running in the memory space. The method implements isolation between the functional module and the platform during the whole process, which can implement of operating a functional module cross platforms without any modification of the functional module, so that the operation is simple. Further, a device of operating a functional module across platforms is also proposed.
