Electronic bill processing method, device and system

Abstract

The invention discloses an electronic bill processing method, which comprises the following steps of: detecting whether a user logs in a chip operating system (COS) with a UKEY function device; when the user is detected to log in the COS, calling bill data in the UKEY function device to process a bill; and detecting whether the UKEY function device communicates with a bill server, and transmitting the data, which are obtained after the bill processing, to the bill server to process the data if the UKEY function device is detected to communicate with the bill server, or temporarily storing the data, which are obtained after the bill processing, in the UKEY function device if the UKEY function device is detected to not communicate with the bill server. The embodiment of the invention also discloses an electronic bill processing device and an electronic bill processing system. When the method, the device and the system are used, the drawback of a 'pure offline' or 'pure online' billing system can be overcome; and by taking the UKEY as a data carrier, the billing system has the advantages of high capacitance, high safety, convenient installation and carrying and the like.

Description

technical field [0001] The invention relates to the field of bill information processing, in particular to a method, device and system for realizing electronic bill processing. Background technique [0002] The existing stand-alone bill issuing system generally adopts the form of a local installation package. After the installation is completed, a system administrator maintains the operator list, enters the bill content, bill number, and stores the issued bill data in the local database. When reporting to the management terminal, use the program to import the data to the U disk, and bring the U disk to the management terminal to declare. If the ticket format changes, you need to re-download the installation package containing the new version of the ticket to reinstall and upgrade. [0003] There is also an online version of the bill issuing system, which adopts the form of a webpage. After the management terminal generates a login password for the client, the bill clerk wil...

AI Technical Summary

Problems solved by technology

[0004] For the stand-alone billing system, the billing data of the system can only be stored in the local machine, and the data must be exported to a USB flash drive or other storage media when declaration is required, and the server cannot know the billing situation of the client in real time

In the implementation of the stand-alone version of the billing system, U-version and other media are used as data transmission tools, which may easily cause the computer at the data receiving end to be infected by viruses

[0005] For the online version of the online billing system, the system must be correctly connected to the Internet to issue bills normally. If the network is abnormal or disconnected, the billing cannot be issued, which does not meet the existing network environment and business requirements.

The online version of the online invoicing system must require the invoicing companies to have access to the Internet, and when the number of invoicing companies reaches a certain peak, there will inevitably be network congestion. When the network congestion occurs, the "pure online" invoicing system cannot issue invoices
