Information statistical method and device

Abstract

The invention relates to an information statistical method and device. The method comprises following steps: calling an intermediate interface provided by a middle layer through an application layer; calling a corresponding hardware module interface of a system layer through the intermediate interface so that the system layer calls matched hardware module to process according to the hardware module interface; obtaining processing information of the matched hardware module returned by the system layer through the intermediate interface and sending the processing information to a message queue; reading processing information of each hardware module from the message queue through the intermediate layer; performing statistics on the processing information of each hardware module according to a preset configuration file through the intermediate layer and generating a statistics file. By means of the above information statistical method and device, the use condition of each hardware module of payment terminals can be flexibly computed; the statistics method is simple and there is no need to consume a large number of resources for application development.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to an information statistics method and device, in particular, to a payment terminal-based information statistics method and device. Background technique [0002] With the rapid development of Internet technology, more and more easy-to-use payment terminals (POS, Point Of Sale) have appeared on the market, which can connect payment terminals with smart devices such as mobile phones and tablets for data transmission. The payment terminal can complete card reading, PIN (personal identification number, personal identification number) input, data encryption and decryption, prompt information display and other operations, so as to realize the application of payment function. [0003] Nowadays, more and more merchants who use payment terminals need to know the usage of each hardware module on the payment terminal, such as the number of successful MODEM (modem) commu...

Problems solved by technology

In the traditional method, each application running on the payment terminal counts the usage of each hardware module. After each application calls the hardware module for use, the payment terminal system returns the processing result to the application, and then the application checks the processing result. For statistics, each application on the payment terminal needs to have the function of counting the usage of each hardware module, the early development consumes a lot of resources, and the statistical method is complicated
