Abstract

The invention provides a method for invoice issuing and authenticity verification in the coal industry, which comprises a bill printing system and a bill verification system. In the method, a two-dimensional bar code is scanned to collect coal bill information, and the authenticity of the invoice is verified by the decryption mechanism of a tax control background system. The method enables the coal industry to meet the policy requirement for billing of the tax control cash register of State Taxation Administration, and meets the service requirement of verifying the authenticity of bills of sale of the coal industry.

Description

The method of a kind of coal industry invoice issuing and authenticity verification

Technical field:

The present invention relates to the method for a kind of coal industry invoice issuing and authenticity verification.Coal industry sales department opens the coal sales invoice that comprises invoice tax control sign indicating number and two-dimensional bar code according to this method by tax-control cash register, coal industry invoice validation department is by scanner scanning coal sales invoice, gather invoice information and invoice tax control sign indicating number, whether the deciphering module checking invoice information by background system of tax control collecting apparatus is consistent with invoice tax control sign indicating number, thereby veritifies the true and false of invoice.

Technical background:

Open by hand make out an invoice leak, true from false of bills checking of coal sales invoice ubiquity falseness and check and write off difficult problem, concrete manifestation is as follows:

(1) true and false difficulty of making out an invoice is distinguished, the falseness leak of making out an invoice is many;

(2) can't gather the electronic bill counterfoil in real time, veritify the information of making out an invoice and have difficulty.

By modernized information approach, by means of network or facility provide a kind of safe, reliably, the solution of coal invoice issuing and veritification efficiently, become coal industry and be badly in need of the difficult problem that solves.

Summary of the invention:

The method that the purpose of this invention is to provide a kind of coal industry invoice issuing and authenticity verification

The objective of the invention is to realize in the following manner, may further comprise the steps:

(1) gives tax-control cash register typing coal sales invoice information by tax-control cash register or by the coal sales system transmissions, drive external bar code printer by tax-control cash register and print the information that contains invoice tax control sign indicating number and two-dimensional bar code invoice;

(2) verification terminal is by the two-dimensional bar code of bar code scan rifle scanning coal sales bill, reduction coal sales invoice information and invoice tax control sign indicating number, whether the decryption mechanisms checking invoice information by background system of tax control collecting apparatus is consistent with invoice tax control sign indicating number, thereby verifies the true and false of this coal sales bill.

Excellent effect of the present invention is

1) encryption chip by tax-control cash register generates invoice tax control sign indicating number, possess safe, the characteristics that data are with a high credibility, invoice data satisfies security and the reliability requirement of the tax bureau to invoice.

2) by the two-dimensional bar code collection, check true from false of bills in real time by means of tax-control cash register GB key mechanism, satisfy the requirement that coal industry ticket checking link in real time, safely, is efficiently veritified true from false of bills.
