The billing system can also comprise a tax control printer connected with the host mobile terminal device, and the tax control printer completes printing operation of the paper invoice after receiving an invoice printing instruction of the host mobile terminal device.
Based on the billing system shown in fig. 2, the present embodiment further provides a billing method applied to tax control, and as shown in fig. 3, the method mainly includes the following steps:
step S1: establishing wireless communication connection between the host mobile terminal equipment and the billing monitoring device, and sending an equipment verification request to the billing monitoring device by the host mobile terminal equipment;
step S2: the billing monitoring device receives a device verification request sent by the host mobile terminal device and performs device verification on the host mobile terminal device;
the host mobile terminal equipment and the invoicing monitoring device establish wireless communication connection through the wireless communication module, after connection, when the host mobile terminal equipment needs to use invoicing software, the host mobile terminal equipment needs to firstly send an equipment verification request to the invoicing monitoring device, the equipment verification request comprises an encrypted personal identification code, and the personal identification code is used for identity verification of the invoicing monitoring device on the host mobile terminal equipment and verifying whether a user is a legal user.
After the billing monitoring device receives a device verification request sent by a host mobile terminal device, a main control security chip decrypts the encrypted personal identification code by using a decryption key prestored in the billing monitoring device to obtain the personal identification code sent by the terminal device, the personal identification code obtained by decryption is compared with the personal identification code prestored in the billing monitoring device, if the two personal identification codes are consistent, the terminal device passes verification and can perform subsequent operation, and if the two personal identification codes are inconsistent, the terminal device fails verification, and the main control security chip sends a verification error prompt to the terminal device. The decryption key is a decryption key which is agreed by the billing monitoring device and the host mobile terminal equipment and corresponds to a key of the host mobile terminal equipment for encrypting the personal identification code.
Step S3: after the equipment passes the verification, the host mobile terminal equipment sends invoice detail data to the invoicing monitoring device according to the invoicing request of the user;
step S4: the invoicing monitoring device judges the legality of the invoicing detail data sent by the host mobile terminal equipment;
step S5: when the tax control code is judged to be legal, the invoicing monitoring device calculates the tax control code according to the stored encryption algorithm and encryption key for calculating the tax control code and sends the tax control code to host mobile terminal equipment;
step S6: host mobile terminal equipment receives and stores the tax control code sent by the invoicing monitoring device, and generates an electronic invoice according to invoice detail data and the tax control code.
When a user needs to make an invoice, firstly, inputting or selecting required invoice detail data on a client interface of invoice making software of host mobile terminal equipment, after the input or selection of the invoice detail data is completed, the host mobile terminal equipment organizes all invoice detail data to send to an invoice making monitoring device, the invoice making monitoring device judges whether the invoice making detail data sent by the host mobile terminal equipment is legal or not according to stored related invoice information and time provided by a real-time clock, if the invoice making detail data is legal, the invoice making monitoring device calculates a tax control code according to an encryption algorithm and an encryption key which are stored by the invoice making monitoring device and used for calculating the tax control code, and sends the tax control code to the host mobile terminal equipment, and the host mobile terminal equipment receives and stores the tax control code sent by the invoice making monitoring device and generates an electronic invoice according to the invoice detail data and the tax control code; and if the invoice detail data are illegal, the invoice making monitoring device gives an error prompt to the invoice making detail data of the mobile terminal equipment.
In practical application, after receiving the tax control code, the host mobile terminal device can be connected with a tax control printer according to the invoice detail data and the tax control code to directly complete the printing operation of the invoice; if the invoice is not required to be printed currently, when the invoice is required to be printed, the host mobile terminal equipment only needs to read invoice detail data and tax control codes in the storage equipment and then print the invoice.
In this embodiment, the invoice detail data includes, but is not limited to, data such as invoicing date, invoice code, invoice number, invoicing type, invoicing amount, taxpayer identification number, and the like. Different invoice types and different invoicing operations correspond to different invoice detail data, for example, the invoice detail of a positive invoice and the invoice detail of a negative invoice are different, and when the positive invoice is invoiced, the invoicing monitoring device needs to check the validity of the following data: the invoicing date, the invoice code, the invoice number, the invoicing amount, the classification amount and the taxpayer identification number; when a negative invoice is invoiced, the invoicing monitoring device needs to check the validity of the following data: the invoice date, invoice code, invoice number and taxpayer identification number are checked according to selectable functional marks in the monitoring management data to determine whether the original invoice is in a tax control disc, whether the invoice date is within the invoice limit days of the negative invoice, and whether the invoice amount and the classification amount are less than or equal to the invoice amount and the classification amount of the original invoice.
When the invoicing monitoring device judges whether the invoicing detail data sent by the host mobile terminal equipment is legal or not, the invoicing monitoring device specifically judges which data items in the invoicing detail are set according to the stipulations of the tax monitoring management department, and can check all the invoice detail data items or some invoice detail data items according to the stipulations; and only if the invoice detail data items to be checked all accord with the setting specification of the invoicing monitoring device, the legality judgment is calculated. For example, the requirement of judging the invoicing date must be consistent, and if the invoicing date in the data is inconsistent with the date read from the real-time clock, an error is reported; if the invoicing date exceeds the invoicing termination time, the invoicing can not be performed, and whether the invoicing date is within the invoicing limit days or not is judged; when judging whether the invoice amount is legal, whether the invoice amount exceeds the maximum limit amount, and whether the invoicing amount and the classification amount are smaller than or equal to the invoicing amount and the classification amount of the original invoice needs to be judged.
The invoicing method provided in the embodiment may further include a step of reporting invoice, that is, tax reporting, to the tax bureau, and when the invoice needs to be reported, one reporting mode is as follows: the host mobile terminal equipment sends a data signature reporting instruction to the invoicing monitoring device, the invoicing monitoring device generates a clock calibration factor according to the instruction, carries out signature on the summary result of the invoice detail data and the clock calibration factor, and finally sends the signature result to the host mobile terminal equipment; the host mobile terminal equipment can directly send the signature result to a tax administration server (provided with tax administration software) of a tax bureau to verify the signature data after the tax administration server successfully receives the signature data, and check and count the submitted data after the verification is passed. After successful completion, the tax administration management software returns the management data ciphertext and the current clock ciphertext to the host mobile terminal device, the host mobile terminal device sends the returned data to the invoicing monitoring device, and the invoicing monitoring device decrypts the data packet, updates the management data and modifies the time. Only the management data for one type of invoice can be updated at a time.
Another tax declaration mode is as follows: the user can also carry the billing monitoring device to directly go to the tax bureau for tax return. The tax administration software of the tax bureau sends a data signature reporting instruction to the invoicing monitoring device, the invoicing monitoring device generates a clock calibration factor according to the instruction, and carries out signature on the summary result of the invoice detail data and the clock calibration factor, and finally sends the signature result to the tax administration server, and the tax administration server carries out subsequent operations such as signature verification and signature verification.
And after the tax is successfully reported, the user determines whether to purchase the invoice according to the condition of the residual number of invoices which are not invoiced. When the invoice is purchased, the tax bureau management software inputs the purchased invoice purchase-receiving information to the invoicing monitoring device.
In this embodiment, the result of summarizing the invoice detail data sent by the invoicing monitoring device refers to summarizing the invoice detail data from the invoicing start time (current time when tax is declared last time) to the current time, in practical application, the invoicing monitoring device does not store the invoice detail data sent by the host mobile terminal device for each invoicing, and the invoicing monitoring device counts and summarizes the invoice detail data once every time the host mobile terminal device successfully invoices or discards one invoice, and stores the summarized result in the invoicing monitoring device, and once the device receives an invoice data sending instruction, the device can directly read the detailed summarized data from the invoicing start time to the current time, and directly perform signature. The time calibration factor is a random number and is used for encrypting the calibration time (used for time calibration of the real-time clock) returned by the tax bureau, the host mobile terminal equipment decrypts the time calibration factor after receiving the encrypted calibration time to obtain the calibration time, and the real-time clock is subjected to time calibration according to the calibration time.
In practical application, a public key corresponding to a private key of the invoicing monitoring device for digital signature can be stored in advance in a server of the tax bureau, or the private key and the public key can be stored in the invoicing monitoring device at the same time, when the digital signature is verified by management software of the tax bureau, the public key in the invoicing monitoring device is obtained through communication with the invoicing monitoring device, or the public key corresponding to the device and stored in the server of the tax bureau is obtained, the public key is adopted to verify the digital signature, and whether signature data are correct is judged.
Specifically, after the host terminal device sends a data submission signature command to the invoicing monitoring device, the invoicing monitoring device generates a 16-byte clock calibration factor, digitally signs a summary result of a series of invoice data such as a start date (4 bytes), an end date (4 bytes) and a classified accumulated amount of invoiced positive invoices generated in the period of time (1), a classified accumulated amount of invoiced positive invoiced negative, and the clock calibration factor by using a private key stored in the invoicing monitoring device for digital signature, and returns the signature result to the host mobile terminal device, and the user can submit a tax or purchase a new invoice to a tax bureau through the invoicing monitoring device and the host mobile terminal device (can be an online tax declaration or a tax bureau for submission).
In the billing system and the billing method provided in this embodiment, the host mobile terminal device can directly utilize the very popular electronic products around the user, such as a mobile phone or a tablet computer, and the billing monitoring device can be made into a device with small volume, low power consumption, rich communication and convenient carrying, such as a bracelet, and the user can perform operations of billing, storing invoice data, online tax reporting and the like only by installing special tax control application software on the mobile phone or the tablet computer, that is, the system can be simplified into a mobile phone plus a 'bracelet'. The user uses the bracelet and is equipped with a smart phone or an IPAD with certain capacity, and billing operation can be carried out. The system can make a user draft and make out an invoice anytime and anywhere, when the invoice needs to be printed, only a wireless printer needs to be connected through a mobile phone and an IPAD (internet protocol digital assistant), the electronic invoice stored in the mobile phone and the IPAD can be printed (the printer needs to place a corresponding paper special invoice), when the user goes to tax office to tax or buy the invoice, the user also needs to go to the tax office through the mobile phone and the bracelet or directly carry the bracelet, and the use convenience of the user is greatly improved.
