POS switch-in group realizing method

Abstract

A method for implementing grouping of POS access, comprising the following steps: 101. Group configuration: configure POS access codes and address information of corresponding POS front-end devices in the same group on the POS access server; 102. Data channel establishment: POS access The incoming server finds the POS front-end processor corresponding to the configuration of the group according to the POS user access code accessed by the call, and establishes a TCP connection with the POS front-end device; at the same time, the POS server negotiates with the POS terminal to establish a data channel; 103. The transaction is completed: The POS terminal exchanges and processes the transaction data through the POS access server, the POS front-end processor and the bank host to complete the transaction process. The invention starts to establish a TCP connection in the calling stage, avoids parsing the transaction data message on the POS access server, thereby shortens the connection time between the POS terminal and the POS front-end machine, and speeds up the transaction process.

Description

[technical field] [0001] The invention relates to a POS system used in the field of financial settlement, in particular to a grouping realization method performed on a POS access server. [Background technique] [0002] The POS terminal is connected with the bank host system through the IP network. When working, "swipe" the bank card on the POS terminal and enter the relevant business information (transaction type, transaction amount, password, etc.), and the POS terminal sends the obtained relevant business information to the bank host through the POS access network. After the bank host performs corresponding processing, it returns the processing result to the POS terminal, thus completing a transaction. [0003] Due to the convenience and speed of the POS card swiping business, the transaction time can be shortened to a large extent. Code and urban public utilities management and many other fields have been widely used. [0004] figure 1 Shown is a POS business network ...

AI Technical Summary

Problems solved by technology

[0016] 2. The POS access server needs to analyze the application layer data message of the POS transaction to obtain the TPDU of the POS user, which makes the processing of the POS access server complicated and may cause incompatibility when the application layer protocol changes

However, due to the existence of these two shortcomings, the POS access server must wait for the POS terminal physical layer and the link layer to pass the negotiation before receiving the transaction data of the POS terminal before grouping and establishing a TCP connection with the bank's POS front-end computer; making the transaction The time becomes longer, which is not conducive to the real-time transaction

Moreover, the POS access server also needs to parse the POS transaction data message, which involves complex protocol processing at the application layer. Once the protocol changes, the POS access server has to be modified for compatibility, which brings inconvenience to the network.
