Description
Technical field
The present invention relates to electronic invoice verify data fields, more particularly, to one kind for testing electronic invoice
The method and system of card.
Background technique
Presently, there are electronic invoice checking system be all online examination service, this online examination, which services, is substantially all
It is the invoice inquiry business of querying condition based on several elements of invoice (such as invoice codes, the amount of money, are made out an invoice the date at invoice number).
Firstly, this examination mode carries out inquiring and authenticating only for electronic invoice information, it can not be to the true and false of electronic invoice layout files
It is verified；Secondly, checking system can not directly give examination as a result, needing user according to query result and the hair being an actually-received
Ticket carries out artificial nominal value comparison and records comparison result, therefore does not support automatically to check, to the subsequent informationization of electronic invoice
Financial application brings inconvenience；Again, the offline examination demand being unable to satisfy under special screne；Finally, electronic invoice can not be verified
Relevance between information and layout files is existed and is cracked down on counterfeit goods the security breaches of invoice using the nominal value element set of true invoice.
(application number: 201611248924.9) a kind of electronics authority unifies checking method and its system to the prior art, is used for
Electronics authority unifies checking system, the echo request including receiving any electronics authority searching platform input, and echo request includes
Electronics authority data to be checked；The corresponding examination code of electronics authority data is generated by preset algorithm；According to examination code, rear
Hold whether inquiry in default storing data library is previously stored with identifying code identical with examination code；If so, returning to electronics authority number
It prompts according to the successful result of examination to corresponding electronics authority searching platform；If no, returning to the mistake that electronics authority is not present
It accidentally prompts to corresponding electronics authority searching platform.However, the prior art, cannot test the layout files of electronics issue of bidding documents
Card does not confirm whether the format of invoice is correct when the data to electronic invoice are verified.
Therefore, it is necessary to a kind of technologies, to realize the technology verified to electronic invoice.
