Method for realizing tax controlled data monitoring of POS system

Abstract

This invention provides one POS system for tax control data monitor method, which comprises the following steps: directly connecting one single machine top case device between POS machine and printer and the top case is connected to the tax control servo through network; when starting system, POS top case getting network control right to judge whether to permit POS work, if yes, then transferring it to POS machine; if not, then stopping switch POS network and receive POS print order.

Description

technical field [0001] The invention relates to a network monitoring method, specifically for the existing POS machine (POS machine, ie, a commercial cash register) networking system, by adding a tax control set-top box and a server to realize the monitoring of tax control data. Background technique [0002] At present, in large and medium-sized commercial places, there are various types of POS machines, that is, commercial cash registers. In accordance with the relevant current national standards, in order to strengthen the tax management, the data in the tax control memory, invoice memory and tax control IC card in the tax control equipment can be guaranteed to be accurate and properly preserved. [0003] as attached Figure 7 In the existing POS machine networking system shown, the business server and the financial server are connected to and monitor multiple POS machine terminals through network cables. Information such as commodity transaction invoice details and daily...

Problems solved by technology

The existing POS machine networking system as described above cannot randomly generate tax control data and load anti-counterfeit tax control codes for the commodity transaction data formed by each POS machine terminal

For example, regular accounting of tax payments usually requires separate financial calculations. The workload is quite huge, and it is not easy to control the real-time inspection of tax control invoices.

[0004] For example, according to the existing POS machine networking system and tax control method, a software module is usually added to the POS machine to generate tax control data by intercepting and monitoring the real-time data of each POS machine; The hardware modification is relatively large, and the design cost is high

Or insert a PCI card into the POS machine, but this kind of method depends on the network environment at the terminal, and there are security loopholes that may easily cause the loss of tax control data, and it is necessary to configure the corresponding PCI card reader device and invest a lot in equipment.
