System for accessing a POS terminal, method for downloading and updating applications and method for performing electronic operation using such a system

摘要

The present invention refers to system for accessing POS terminals (10), with or without pin pad, using a client system (15) to connect such POS terminal (10) to a network comprised by at least one server (30), the system enabling any POS terminal (10) to execute applications (25) located in such servers, through a plurality of specific protocols (20) in a process similar to the Internet, as well to download and update applications from application servers (30) and to perform electronic operations in transaction serves (35).

主权项

1. A system for supporting Web applications on a point-of-sale (POS) terminal, the system comprising:
a client apparatus configured to connect the POS terminal to a network using a plurality of communication protocols and transaction protocols, transaction protocols including at least HTTP, ISO8583 and XML operations; the client apparatus including at least one customized WML and Script extension added to preexisting WAP standards to form an application development and runtime environment for developing applications for download and use on the POS terminal, the client apparatus comprising a processor and a memory having computer code stored therein, the computer code configured, when executed by the processor, to cause the client apparatus to:
download, run, and update applications from application servers connected to the network using HTTP on top of TCP/IP;enable one or more applications to use multiple communication protocols when connected to distinct access networks;extend a web based runtime environment to perform electronic ISO8583 operations using POS peripheral devices, the web based runtime environment configured to support persistence of information and to prevent multi-application interference by supporting multi-applications independently carried out in logical distinct environments; andrecognize, access, and control a plurality of POS peripheral devices, the POS peripheral devices comprising input and output peripheral devices, wherein the system further comprises: transaction servers configured to be accessed by the client system for executing electronic operations using different transaction protocols.
