Terminal offline charging service method and system

Abstract

The invention relates to a terminal offline charging service method and system. The method includes the following steps: a user requests a service from a charging terminal; the charging terminal generates a random password and related identifier information and encrypts the random password; a user terminal receives the random password encrypted by the charging terminal and the identifier information, and sends the random password and the identifier information to an application server; the server decrypts the encrypted random password and provides a payment interface to the user terminal for the user to make payment; after the application server confirms that the user has made payment, the decrypted random password is sent to the charging terminal through the user terminal; the charging terminal receives the decrypted random password and verifies the decrypted random password, and provides the a corresponding service after the verification is successful. In the whole process of the charging service, the charging terminal is in an offline state, that is to say, the terminal and the server are not connected via a network, so the operation cost of a charging system is greatly saved and the deployment difficulty of the charging terminal is reduced.

Description

Technical field [0001] The present invention relates to the field of self-service charging services, in particular to a method and system for charging service of offline terminals. Background technique [0002] With the development of communication and electronic technology, e-commerce has become an indispensable part of people’s lives. In most cities, self-service charging services are everywhere, such as vending machines, automatic coffee machines, etc. However, the current self-service The charging service system generally connects the charging terminal and the application server on the network, and deploys it online, which leads to the need to maintain a wired or wireless channel between the application server and the charging terminal. This type of deployment has the following defects: Operators pay high channel fees; if wired deployment is adopted, there will be greater restrictions on the deployment location of toll terminals. After all, laying out network cables is a cumb...

[0002] With the development of communication and electronic technology, e-commerce has become an indispensable part of public life. In most cities, self-service charge service equipment can be seen everywhere, such as automatic vending machines, automatic coffee machines, etc. However, the current self-service Toll service systems generally connect toll terminals and application servers to the network and deploy them in an online form, resulting in the need to maintain a wired or wireless channel between the application server and toll terminals. This deployment method has the following disadvantages: Operators pay high channel fees; if wired deployment is adopted, the deployment location of toll terminals is greatly restricted. After all, laying network cables is a cumbersome project, and wired lines are easily damaged and difficult to maintain; toll terminals must be kept at all times. online state, will result in large power consumption
