Detailed ways

The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation modes.

Embodiment 1

This embodiment provides an offline payment method, which is mainly used for offline payment of service machines, including washing machines, dryers, dehydrators, etc. The offline payment method will be described in detail below, taking a washing machine as an example.

Figure 1 is a flow chart of the offline payment method in this embodiment. The offline payment method for the washing machine will be described in detail below with reference to Figure 1 . The offline payment method mainly includes the following steps: the washing machine obtains the service function selected by the user and generates a payment code; the mobile terminal obtains the payment code, and after the payment is successful, obtains the verification code corresponding to the payment code in the background server; Enter the corresponding verification code on the washing machine, and the washing machine will start running when the entered verification code matches the verification code stored in it.

When the washing machine does not have a network or the network signal strength is poor, the method described in this embodiment can be used to obtain the information on the washing machine through the mobile terminal, and then the user inputs the information from the mobile terminal to the washing machine, thereby realizing indirect interaction between the washing machine and the mobile terminal, and Through the direct interaction between the mobile terminal and the backend server, offline payment is realized, ensuring that the user can use the washing machine normally, without delaying the user's use because the washing machine cannot interact with the backend server, and improving user satisfaction.

Embodiment 2

This implementation is further improved on the basis of Embodiment 1. Figure 2 is a flow chart of the offline payment method in this embodiment. The offline payment method for the washing machine will be described in detail below in conjunction with Figure 2. This offline payment method mainly includes the following steps:

Step 1. Select the service function on the washing machine. The washing machine will generate the payment amount based on the selected service function; confirm whether the payment amount is correct.

The washing machine in this embodiment is provided with a display screen connected to the washing machine controller, and the corresponding service function can be selected by touching the display screen, wherein the service function includes selecting quick washing or step washing; wherein the fast washing includes standard one The step-by-step washing process includes selecting at least one of a washing program, a rinsing program, a dehydration program, and a drying program.

Among them, the standard one-button washing program, the one-button washing program corresponding to each type of clothing, and each program in step washing correspond to corresponding amounts.

Users can select service functions according to their actual situation, and the washing machine will generate a payment amount based on the service functions selected by the user and display the payment amount on the display. Users can check the corresponding charging standards through the display of the washing machine in advance, and check whether the payment amount displayed on the display is correct according to the selected service function.

In this embodiment, the user can also view the corresponding charging standards through the mobile terminal, or the charging standards pasted on the top plate of the washing machine, so that the user can directly view the relevant charging standards.

Step 2: If yes, the washing machine generates a payment code; then the washing machine fault is confirmed and the fault information is recorded.

The payment code in this embodiment may be any of a numeric code, an alphabetical code, a mixed code of numeric and alphabetic characters, a QR code or a bar code.

When the washing machine fails, the washing machine will be suspended from use. When it can connect to the back-end server, the washing machine will promptly update the fault information to the back-end server so that the staff can repair the faulty washing machine in time.

Step 3: The mobile terminal obtains the payment code generated by the washing machine.

The mobile terminal is a mobile phone, tablet computer, etc. The mobile terminal described in this embodiment is a mobile phone, and an APP capable of communicating with the background server is installed in the mobile phone.

Since there are many types of payment codes, different types of payment codes may use different methods for the mobile terminal to obtain the payment codes generated by the washing machine.

Specifically, if the payment code adopts any of a numeric code, an alphabetical code or a mixed code of numeric and alphabetic characters, the payment code is displayed on the display, and the user reads the payment code displayed on the display and puts the payment code on the display. The payment code is entered into the mobile terminal. If the payment code is a barcode or QR code, the user can scan the barcode or QR code displayed on the display through the APP, so that the mobile terminal can obtain the payment code.

Step 4: Pay according to the payment code. The mobile terminal sends the payment code and payment information to the backend server. The backend server sends the verification code corresponding to the payment code to the mobile terminal.

If the payment code uses any of a numeric code, an alphabetic code, or a mixed code of numeric and alphabetical characters, in order to ensure that the payment code entered by the user is correct, after the user enters the payment code on the mobile terminal, the user is required to confirm the entered payment code. Is it correct? If confirmed, select OK and pay. The mobile terminal will send the payment code and payment information to the backend server. If the payment code uses a barcode or QR code, when the mobile terminal obtains the payment code by scanning the code, it will jump directly to the payment page, and the user can make payment directly.

Each washing machine stores multiple check codes, and the check codes in the backend server correspond to the check codes and payment codes in the washing machine. The backend server receives the payment sent by the mobile terminal each time. When the payment code is entered, the backend server will send the verification code corresponding to the payment code to the mobile terminal.

In this embodiment, the check code is any one of a numeric code, an alphabetic code, or a mixed code of numeric and alphabetical characters. In order to reduce the possibility of being cracked, the check code is usually set to a mixed code of alphanumeric characters.

Step 5: Enter the verification code into the washing machine, and the washing machine will accumulate the number of times the verification code corresponding to the current payment code has been entered.

Each time the washing machine generates a payment code, it will display the payment code for a preset time, and automatically jump to the page for entering the verification code after the preset time. After the user enters the verification code into the washing machine and confirms the input, he clicks "Confirm". Each time he clicks "Confirm", it is considered that the verification code has been entered. In order to avoid the situation where the check code corresponding to the payment code is obtained after repeated input for many times without payment, this embodiment limits the number of times of inputting the check code. Usually the number of inputs is set to 2 or 3 times.

In order to avoid using the same verification code on different washing machines and successfully pairing, it is necessary to ensure that the verification code and payment code stored in each washing machine have different matching forms, that is, the same payment code in the two washing machines must match Different verification codes, and the same verification code in two washing machines need to correspond to different payment codes.

Step 6: Determine whether the number of times the verification code corresponding to the current payment code has been entered is greater than the preset number of times; if so, the current payment code and the verification code corresponding to the current payment code are invalid, and payment needs to be made again and a prompt will be displayed for the order. Automatic refund; if not, determine whether the check code corresponding to the current payment code of the washing machine matches; if yes, the washing machine starts running; if not, re-enter the check code.

When verifying whether the entered verification code matches the verification code corresponding to the current payment code of the washing machine, first confirm whether the entered verification code is consistent with the verification code stored in the washing machine, and then determine whether the current verification code of the washing machine is consistent with the current payment code. Whether the payment code corresponds; only when the entered verification code is consistent with the verification code stored in the washing machine, and the entered verification code corresponds to the current payment code, can the entered verification code and the current payment of the washing machine be confirmed The check code corresponding to the code matches.

When the current payment code and the verification code corresponding to the current payment code are invalid and payment needs to be made again, the washing machine will prompt the user that the order will be automatically refunded, that is, it will be displayed on the display that the order will be automatically refunded, and will be displayed for a period of time. Then jump directly back to the initial page, that is, the page where the user can select service functions.

If the current payment code and the verification code corresponding to the current payment code are invalid and payment needs to be made again, since the user has paid but has not used the washing machine, the corresponding order needs to be refunded. The specific refund process is as follows:

When the washing machine can communicate with the back-end server, the washing machine automatically updates the successfully matched verification code to the back-end server; the back-end server will confirm that the payment is successful but the matching is not successful based on the successfully matched check code and the verification code sent to the mobile terminal. Successful verification code; the backend server will refund orders corresponding to successful payment but unsuccessful matching of the verification code.

Generally, this type of washing machine will automatically prompt the user on how to operate it correctly, what kind of operation is wrong and how to refund the operation process before starting to use it; and the corresponding operation process is also pasted on the top wall of the washing machine, and there is also a corresponding one on the mobile terminal. Operation process, users can choose any method to view the relevant operation process; so that users can understand how to use this type of washing machine.

Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. An exhaustive list of all implementations is neither necessary nor possible. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
