A pos terminal communication method and system

Abstract

The invention discloses a POS terminal communication method. The method is characterized in that S1, a POS terminal sends transaction information to a background server through at least two communication modes. The invention also discloses a POS terminal communication system. The system comprises the POS terminal and the background server, wherein the POS terminal is used for sending the transaction information to the background server through the at least two communication modes; and the background server is used for processing the transaction information which is firstly delivered. By using the POS terminal communication method in the invention, a transaction information communication success rate of the POS terminal is increased and a user experience is improved. In the POS terminal communication system, the POS terminal and the background server are combined so as to solve a problem that a processing speed is slow and reduce a failure rate of POS terminal transaction and a reversal rate of a background. The POS terminal communication method and the system can be widely used in the POS terminal communication field.

Description

technical field [0001] The invention relates to the field of POS terminal communication, in particular to a POS terminal communication method and system. Background technique [0002] Thread: is a single sequential flow of control in a program. A relatively independent and schedulable execution unit in a process, which is the basic unit for the system to independently schedule and allocate CPU, and refers to the scheduling unit of the running program. Running multiple threads simultaneously in a single program to do different tasks is called multithreading. [0003] Socket: Two programs on the network exchange data through a two-way communication connection, and one end of this connection is called a socket. [0004] The POS system is the point-of-sale information system, which refers to the direct reading of product sales information (such as product name, unit price, sales quantity, sales time, sales store, buying customers, etc.) ), and transmit it to relevant departme...

AI Technical Summary

Problems solved by technology

Due to the versatility of the POS terminal, it is determined that it will be used in various industries, and the use is scattered and cannot be concentrated, resulting in different use environments, insufficient communication adaptability, poor communication stability, slow transaction communication speed, and low reliability; In addition, most of the places used are crowded places, and the network reliability is complex and changeable

[0006] When the POS terminal is in the transaction, after the user swipes the card, when the POS terminal sends the transaction data to the background, the transaction speed is often slow due to the poor network environment and low reliability, and it takes a long time to return the transaction result. , and the slow transaction result will inevitably lead to a high transaction failure rate or background correction, and the user experience is very poor
