Abstract

The utility model relates to an anti-counterfeiting bill processor. The existing congener equipment has the disadvantages of high cost and expensive price, and is not suitable for majority small-scale taxpayers. The utility model comprises a CPU, a memory, a keyboard, a display, an IC card reader-writer and a magnetic strip reader-writer which are connected with the CPU. The anti-counterfeiting bill processor has the anti-counterfeiting function of inspection bill authenticity and validity, and can create necessary conditions for unidirectional and crossed check. The utility model simultaneously has the advantage of low cost, and is suitable for popularization and use in middle and small taxpayers.

Description

The false proof bill processor

The utility model belongs to a kind of false proof bill processor.

The management of advancing tax amount of offset item is the important step of value added tax standardized management work, authenticity of drawing a bill and legitimacy in order to guarantee, tax administration department controls with special invoice cross audit system and anti-false tax-controlled system, the used hardware price height of this type systematic in the prior art, general small enterprise is with not rising, so a large amount of small-scale taxpayers can not enter the supervisory system of unification of the motherland, make administrative authority out of control to the legitimacy and the authenticity of this part enterprise tax invoice of opening in advancing to sell to.

It is low that the utility model aims to provide a kind of cost, easy to use, has antiforge function and can be unified monitoring, check the false proof bill of essential condition processor is provided.

Realize that the above-mentioned purpose technical scheme is: this processor comprises CPU, the storer, keyboard, the display that link with CPU, it is characterized in that, this processor also is provided with an IC-card read write line that links with CPU and can the reading and writing IC card content, and the magnetic stripe read write line that can read and write the magnetic stripe content that links to each other with CPU.

Principle of work of the present utility model and using method are: each household enterprise has through this processor of authorizing numbering and the IC-card that matches, put on record at its competent authorities' central database simultaneously, this enterprise uses IC-card when competent authorities buy blank invoice, competent authorities deposit invoice that this IC-card is purchased coding in central database, also write simultaneously IC-card, this enterprise need be when the buyer provides invoice as the seller, earlier IC-card is inserted the IC-card read write line, CPU judge this IC-card coding whether with this processor codes match, as be not inconsistent, CPU withdraws from by display prompts, if meet, display prompts is imported this numbering of opening invoice and related content, after keyboard input invoice number and related content, CPU compares judgement with the data that it deposits IC-card when buying invoice in, make the answer of " correct/error ", if it is correct, promptly can open the content of invoice with the keyboard input with display prompts, write the IC-card and the magnetic stripe (data are for changing) of this processor behind the invoice content-encrypt of CPU with input, simultaneously that the invoice content is hand-written or beat on invoice with external printer, to be attached to the magnetic stripe of invoice content at last on the offsetting slip of invoice and give the buyer, promptly finish this operation of making out an invoice.

This processor can check invoice to provide people and possessor's consistance by IC-card, thus the legitimacy of certified invoice, and the data of providing invoice with the utility model can have two backups: 1, the seller's IC-card; 2, be pasted on the buyer and hold magnetic stripe on the invoice offsetting slip; Like this seller competent authorities can by IC-card readout device inspection read the invoice content whether with the IC-card data consistent, whether invoice offsetting slip content can be read by the inspection of magnetic stripe readout device by buyer competent authorities consistent with the content that writes magnetic stripe, to realize unidirectional checking, check the authenticity of invoice, on the other hand, if after the seller's IC-card, the buyer's magnetic stripe content being deposited in the central database of competent authorities separately respectively, can be both sides competent authorities again and bill is carried out cross audit establish indispensable basis.This device antiforge function is strong, and cost is low, and low price is beneficial at medium-sized and small enterprises and applies, and is convenient to national management department a large amount of small-scale taxpayers are carried out the unified monitoring of paying taxes.

The embodiment explanation:

Referring to being CPU and memory portion in figure two, the frame of broken lines A.

This routine CPU is that the AT89C52 that atmel corp makes forms.

This routine storer comprises external program memory EPROM27C256, latch HC573, can realize the code translator AmPAL16R8B of different big or small spaces addressing function, non-volatile private data storer AT29C010.

In the use, important procedure (as check IC-card coding and the machine code that matches etc.) is deposited among the 8KROM that CPU carries, require outage needs such as not lose, maintain secrecy, can rewrite to satisfy this part important procedure; Deposit general procedure in external program memory, can realize expanding function easily; Data messages such as IC-card, magnetic stripe to input deposit non-volatile private data storer in, can not change to guarantee these information requirements, are difficult for losing, needs (preventing that the user from changing data privately) such as maintain secrecy;

This example is made clock chip with DS12887.

This routine magnetic stripe read write line is connected with CPU with the PC mouth by the PA of interface 8255, and CPU comes drive stepping motor by 8255 driving transistorss, 8550 gauge tap CON2 simultaneously, and in order to transmission magnetic stripe (seeing figure three E), the Stepping Motor Control signal is from parallel interface.

This routine IC-card read write line uses IC-card and the deck that meets the ISO7816 standard, is connected (seeing figure three F) with CPU by contact pin JP2.

The special-purpose display screen of the band Chinese character base that this routine LCD LCD selects for use Tsing Hua Tong Fang to produce, this special use display screen can directly insert in contact pin JLCD1 and upward link to each other with data bus, and the required negative supply of this LCD display provides (seeing figure three G) by the 7660 negative supply change-over circuits of forming.

This routine keyboard is made up of function key, letter key and numerical key, can import Chinese character, English alphabet and numeral, and keyboard is connected (seeing figure three D) by interface SN74LS164 with CPU

This routine set device serial line interface is formed (seeing figure two B) by MAX232AA and 9 coupled pin serial socket DB1, and parallel interface is formed (seeing figure two C) by 82C55 and the coupled parallel socket DB1 of 25 pins.

During practical application, when needing, CPU can be connected with PC by serial line interface, and PC receives initialization command or other steering order, controls printer or connects networking with central database.

The utility model also can be networked as the terminal device of unified monitoring network with the central database of the competent department of taxation, also can utilize specific software used for administrative authority, legitimacy as check IC-card that enterprise holds after linking with central database, be the numbering of enterprise's IC-card input with enterprise terminal processor coupling, deposit the IC-card content in central database, check that enterprise holds the content of offsetting slip magnetic stripe, deposit offsetting slip magnetic stripe content in central database etc.

Claims
