Magnetic card signal simulator

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.

Method, apparatus, and system for testing terminal

Embodiments of the invention disclose a data transmitting method, a server and a client. The method embodiments of the invention include: obtaining a client application list file uploaded by a client; determining whether a file in a object application list file exists in the client application list file, and determining whether a hash value sha2 of the file in the object application list file is identical to a hash value sha2 of a file in the client application list file; adding the non-existed file into an incremental file list when the file in the object application list file does not exist in the client application list file; adding a file which is not identical into the incremental file list when the hash value sha2 of the file in the object application list file is different from the hash value sha2 of the file in the client application list file; packaging and compressing the object application list file, a signature file of the object application list file and the file in the incremental file list to create an incremental upgrade package such that the client can upgrade the application package through the incremental upgrade package.

Data transmitting method, server and client

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.

Method and device of running application program across systems

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.
