POS machine, industrial control computer, system equipped with POS machine and industrial control computer, and method for system

Abstract

The invention provides a POS machine, an industrial control computer, a system equipped with the POS machine and the industrial control computer, and a method for the system. In the system with the POS machine and the industrial control computer, the POS machine enables a submitted data package to be encrypted when the POS machine is used for card-swiping payment, and transmits the data package to the industrial control computer in a mode of IP transfer. When the industrial control computer receives the data package from the POS machine, the industrial control computer carries out the integrity verification of the data package, and transmits the data package to a payment service system in a routing manner. When the industrial control computer receives payment service processing results from the payment service system, and transmits the data package of payment service processing results to the POS machine. The POS machine carries out the decryption and processing of verification integrity of the data package from the industrial control computer.

Description

technical field [0001] The invention relates to a POS machine, an industrial computer, a system with the POS machine and the industrial computer and a method thereof, in particular to a method and a system for networking the POS machine through a serial port. Background technique [0002] At present, there are more and more self-service devices used for sales business, and more and more POS machines are used when users swipe their cards for payment. Usually, POS machines are equipped with SIM cards, which can be accessed through the operator's dedicated 2G network. The payment service system completes the payment function. [0003] The so-called POS machine refers to the electronic cash register (Point Of Sale), which is a multi-functional terminal. It has functions such as supporting consumption, pre-authorization, balance inquiry and transfer, and is safe, fast and reliable to use. [0004] figure 1 It shows the composition diagram of the payment logic module composed of...

AI Technical Summary

Problems solved by technology

For example, the actual environment where the self-service equipment is placed is relatively closed in many places (for example: at the entrance of the corridor), and it is difficult to cover the 2G network, which affects the location of the self-service equipment.

[0008] When the self-service equipment is placed in densely populated places (such as office buildings), due to the limitation of 2G network base stations online at the same time, the 2G network of the POS machine is often kicked out of the link, causing the 2G network signal of the POS machine to be unstable and affecting user experience

[0009] Because the POS machine uses the 2G network to communicate with the payment service system, a specific SIM card needs to be installed on the POS machine, and a fee needs to be paid every year, which has the problem of high cost.
