Description

Technical Field

[0001] The present invention relates to the technical field of payment terminals, and in particular to a method and system for automatically downloading SN and a key at a payment terminal. Background Art

[0002] During the production process, payment terminals usually need to download data information such as SN and keys before they can be used normally. The common method of downloading SN and keys during the production process of payment terminals is to connect the barcode scanner and the payment terminal to the computer via a data cable, scan the SN barcode or QR code attached to the payment terminal device to the computer through the barcode scanner, and then download it to the payment terminal through the computer tool. This operation method requires unplugging the data cable and plugging in another device after downloading one device, which is troublesome. Summary of the invention

[0003] To solve the above problems, the present technical solution provides a method for a payment terminal to automatically download SN and key.

[0004] To achieve the above purpose, the technical solution is as follows: A method for automatically downloading payment terminal data, comprising the following steps: S1: The mother terminal is configured to simulate the NFC tag card mode and electrically connected to the conveyor belt control device, and the child terminal is set to the NFC card reader mode; S2: The sub-terminal is labeled with identification information, and when the sub-terminal is turned on, if it determines that the SN and key information do not exist, it enters the download mode, or enters the download mode by pressing a button, and continuously sends a card search instruction; wherein the identification information includes a barcode or a QR code; S3: The mother terminal controls the conveyor belt through the conveyor belt control device, so that the sub-terminal on the conveyor belt moves to the position corresponding to the code scanning device, and the code scanning device automatically scans the identification information on the sub-terminal and transmits it to the mother terminal; S4: The conveyor belt continues to work. When the sub-terminal approaches the mother terminal, the mother terminal responds to the card search instruction of the sub-terminal and establishes a communication link, and controls the conveyor belt to stop; S5: The mother terminal sends the NDEF format data including the SN and key information to the child terminal; S6: After the sub-terminal completes data reception, the NFC function is turned off; S7: Repeat steps S3-S6; or the steps are ended, and the mother terminal controls the conveyor belt to stop.

[0005] The method for automatically downloading payment terminal data as described above also includes a computer terminal, the code scanning device is electrically connected to the computer terminal, and the mother terminal is electrically connected to the computer terminal.

[0006] In the above-mentioned method for automatically downloading payment terminal data, in step S3, the code scanning device scans the identification information on the sub-terminal and transmits it to the computer terminal. The computer terminal obtains the corresponding SN and key information and transmits it to the main terminal.

[0007] In the above-mentioned automatic downloading method of payment terminal data, in step S5, the mother terminal converts the SN and key information into text format and packages the data in NDEF format as the card data of the simulated NFC tag card. The mother terminal starts to enter the simulated NFC tag card mode and continues to listen for whether there is a card search instruction.

[0008] In the method for automatically downloading payment terminal data as described above, in step S6, the sub-terminal sends a card reading instruction to the mother terminal, and the mother terminal sends the data to be sent to the sub-terminal as response data to the sub-terminal. After receiving the data, the sub-terminal performs parsing processing. The sub-terminal converts the data to be sent to the mother terminal into a text-encapsulated NDEF format and transmits it to the mother terminal through a card writing instruction. After receiving the card writing data, the mother terminal performs parsing processing.

[0009] In the above-mentioned automatic downloading method of payment terminal data, in step S7, the mother terminal exits the simulation card mode after confirming that all information has been transmitted and issues a command to control the conveyor belt to continue rotating. After determining that all information has been received, the sub-terminal turns off the NFC function and exits the download mode.

[0010] In the above-mentioned automatic downloading method of payment terminal data, in step S7, when the mother terminal does not receive the identification information scanned by the code scanning device within a preset time, the conveyor belt is controlled to stop.

[0011] In the above-mentioned method for automatically downloading payment terminal data, the processing steps of the sub-terminal are: S01: Enter download mode; S02: Send a card search command; S03: if the card search instruction is responded, go to the next step; otherwise, return to step S02; S04: Enter card activation mode; S05: After receiving activation feedback, proceed to the next step; otherwise, return to step S02; S06: Enter card reading mode; S07: After receiving the response feedback, proceed to the next step; otherwise, return to step S02; S08: Process data and issue card reading and writing instructions; S09: After receiving the response feedback, proceed to the next step; otherwise, return to step S02; S10: The processing is completed and the step ends; otherwise, return to step S06.

[0012] In the above-mentioned method for automatically downloading payment terminal data, the processing steps of the mother terminal are: S21: Initialization; S22: SN and key information are detected, and the next step is entered; otherwise, step S22 is repeated; S23: Enter the NFC tag card simulation mode; S24: After receiving the card search instruction, proceed to the next step; otherwise, repeat step S24; S25: responding to the card search instruction and triggering the conveyor belt control device to stop the conveyor belt; S26: After receiving the activation instruction, proceed to the next step; otherwise, repeat step S26; S27: receiving response feedback; S28: If the card reading and writing instruction is received, proceed to the next step; otherwise, repeat step S28; S29: perform data processing; S30: The processing is completed, the conveyor belt control device is triggered, the conveyor belt is started, and the step ends; otherwise, return to step S28.

[0013] A payment terminal data automatic downloading system comprises a computer terminal, a code scanning device electrically connected to the computer terminal, a mother terminal electrically connected to the computer terminal, a conveyor belt control device electrically connected to the mother terminal, a conveyor belt electrically connected to the conveyor belt control device, and a sub-terminal.

[0014] The beneficial effects of this application are: The present invention provides a method for automatically downloading data from a payment terminal, which is a data downloading method that does not require plugging in a data cable, that is, a method for short-distance transmission using NFC. The mother terminal is simulated into an NFC tag card, and the child terminal uses a card reader mode. When the child terminal is close to the mother terminal, data transmission is achieved through NFC to achieve information download, eliminating the trouble of plugging in and out of the data cable.

[0028] like Figure 1 As shown, a payment terminal data automatic downloading system includes a computer terminal 1, a code scanning device 2 electrically connected to the computer terminal 1, a mother terminal 3 electrically connected to the computer terminal 1, a conveyor belt control device 4 electrically connected to the mother terminal 3, a conveyor belt 5 electrically connected to the conveyor belt control device 4, and a sub-terminal 6.

[0029] The working principle of this embodiment: 1. Find a payment terminal with NFC function (called sub-terminal) and an automatic code scanning device (can be a code scanning gun or a payment terminal with code scanning function), and connect them to the computer through data cables. The sub-terminal acts as a card reader, and the sub-terminal implements the card simulation function on the mother terminal device, and the mother terminal is connected to the conveyor belt control device.

[0030] 2. Add a function mode of downloading SN and key through NFC on the payment terminal (sub-terminal) that needs to download information. Turn on the machine and judge whether SN does not exist or press a certain button to enter this mode. In this mode, the sub-terminal continuously sends card search instructions through NFC to detect whether there is a mother terminal simulation card approaching.

[0031] 3. Place the automatic barcode scanning device and the mother terminal next to or above the conveyor belt on the production line and adjust the position and angle so that when the child terminal is conveyed to the barcode scanning device, the barcode scanning device can quickly and accurately scan the barcode or QR code content. When the child terminal is conveyed to the mother terminal, the child terminal can recognize the card simulated by the mother terminal.

[0032] 4. During production, after the previous workstation has tested the basic functions of the sub-terminal, affix a barcode or QR code to the corresponding position of the sub-terminal, and let the sub-terminal enter the mode of downloading SN information through NFC, then put the sub-terminal on the conveyor belt and adjust the angle.

[0033] 5. When the sub-terminal is transferred close to the code scanning device, the SN code information attached to the sub-terminal is scanned and transmitted to the computer-side tool. If the key needs to be downloaded, the tool sends the SN to the background server to obtain the key information corresponding to the SN, and then transmits the SN and key information to the mother terminal. The mother terminal converts the data information into text format and encapsulates the data in NDEF format as the card data of the simulated card. The mother terminal starts to enter the simulated card mode and listens for card search instructions.

[0034] 6. When the sub-terminal approaches the mother terminal through the conveyor belt, the mother terminal responds after receiving the card search command. After receiving the response, the sub-terminal sends a command to further confirm whether the mother terminal simulated card is detected and activated. After receiving the activation command, the mother terminal responds and sends a command to control the conveyor belt to stop transmission and wait for the information download to be completed.

[0035] 7. After the sub-terminal establishes a data link with the mother terminal, the sub-terminal sends a card reading command to the mother terminal. The mother terminal sends the data to be sent to the sub-terminal as response data to the sub-terminal. After receiving the data, the sub-terminal performs parsing and processing. The sub-terminal converts the data to be sent to the mother terminal into text package NDEF format and transmits it to the mother terminal through the card writing command. After receiving the card writing data, the mother terminal performs parsing and processing. After confirming that all information has been transmitted, the mother terminal exits the simulated card mode and issues a command to control the conveyor belt to continue rotating. After judging that all information has been received, the sub-terminal turns off NFC and exits the download mode.

[0036] 8. Repeat steps 4 to 7 through the above operations to realize the automatic download of SN, key and other information, eliminating the trouble of plugging and unplugging data cables and saving labor costs.

[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
