Anti-locking method of an anti-counterfeit tax control module

Abstract

The invention relates to an anti-locking method for an anti-counterfeiting tax-control module. The method comprises the following steps that: Step 1, an enabling date and locking enabling release authorization are written into the anti-counterfeiting tax-control module; step 2, whether the locking enabling release authorization indicates locking or not is judged, if the locking enabling release authorization indicates locking, step 3 is executed, otherwise, step 7 is executed; step 3, whether a date setting state of the anti-counterfeiting tax-control module is in a setting accomplished state or not is judged, if the date setting state of the anti-counterfeiting tax-control module is the setting accomplished state, step 5 is executed, otherwise, step 4 is executed; step 4: tax related dates of the anti-counterfeiting tax-control module are set, and the date setting state of the anti-counterfeiting tax-control module is modified as a setting accomplished state; step 5, whether a current date is earlier than the enabling date in the anti-counterfeiting tax-control module is judged, if the current date is earlier than the enabling date in the anti-counterfeiting tax-control module, step 6 is executed, otherwise, step 7 is executed; step 6, a massage that the anti-counterfeiting tax-control module has not been enabled is outputted, and the method terminates; and step 7, the anti-counterfeiting tax-control module is utilized to record ciphertexts on invoices to be invoiced. With the anti-locking method for the anti-counterfeiting tax-control module of the invention adopted, the anti-counterfeiting tax-control module can be prevented from being locked because the enabling data is later than a valid date.

Description

technical field [0001] The invention relates to the technical field of tax collection, in particular to an anti-locking method of an anti-counterfeit tax control module. Background technique [0002] The existing tax collection technology requires merchants to be equipped with an anti-counterfeiting tax control module. The anti-counterfeiting tax control module has a validity period. Usually, its validity period is a tax collection period. If the current date exceeds its validity period, the anti-counterfeiting tax control module If the validity period is not extended in advance, the anti-counterfeiting tax control module will be locked. The function of the anti-counterfeiting tax control module is: when the merchant issues an invoice, the invoicing opportunity will encrypt the invoice date, bill flow, the national unified code of both buyers and sellers, transaction amount and tax amount to form a ciphertext. In addition to printing the ciphertext on the invoice issued by ...

Problems solved by technology

However, since each tax authority is facing a large number of merchants, it takes a period of time between the issuance of the anti-counterfeiting tax control module to the merchants and its official use to complete the release of the anti-counterfeiting tax control module, system debugging and other work. When the interval is too long and the activation date of the anti-counterfeit tax control module is later than its validity period, even if the merchant has not activated the anti-counterfeit tax control module to issue invoices, it must be extended to the tax authority. Otherwise, the anti-counterfeit tax control module group will be locked

Obviously, this wastes time and increases the workload of tax authorities and merchants
