Description

Bar code display method, equipment and device

Technical field

The present invention relates to the field of information technology, in particular to a bar code display method, equipment and device.

Background technique

With the popularization of mobile payment technology, users can use a payment application APP (Application) installed on a terminal (such as a mobile phone) to make a payment. In addition, in the era of mobile Internet, various service media such as cards and coupons are gradually virtualized and electronic. Users only need to select and display the QR code/barcode of the card and coupon through their mobile phones to enjoy the corresponding services.

For apps with card package functions, due to the many types of cards and coupons they manage, how to quickly select and display QR codes/barcodes in places where the service is used will seriously affect the service experience of the app. Taking a user using a specific APP to take a bus as an example, there are two ways for the user to choose the QR code of the bus card. One is to select the card package function and choose the bus card to swipe the code; the other is to choose to pay and choose to take the bus Code. If the currently displayed card is the corresponding bus card, it can be used directly. If it is showing other bus codes (such as subway bus codes), you need to switch to the bus card and use it again. In scenarios where the target QR code needs to be quickly selected (for example, when a large number of passengers are queuing behind the bus in the morning and rush hours), such an operation method will bring a very poor experience to the user.

Summary of the invention

In view of the above problems in the prior art, the embodiments of the present invention provide a novel barcode display method, device and device, which can intelligently display barcodes that users may use, provide users with a good experience and help APP Improve customer retention rate.

Conventionally, in order to help users quickly select, locate, and display QR codes/barcodes, apps with card package functions usually adopt the following two solutions:

1. Classification scheme-according to the service category of the card and voucher, for example, the barcode and the travel code in the APP payment function are classified, and the user can quickly choose to use the service when using the service. The disadvantage of this solution is that when the user has a large number of cards and coupons of the same type, the user's operating experience cannot be significantly improved.

2. The recently used priority display scheme-display the cards and coupons in the order in which they are used. The scheme assumes that the cards and coupons that the user recently used will continue to be used. The disadvantage of this scheme is that not all users' card and coupon usage satisfy this behavior.

In order to solve the problems of conventional APP card coupon display, an embodiment according to the first aspect of the present invention provides a barcode display method, which includes using a processor to execute the following processing actions:

Obtain the usage characteristic variables when using the barcode through the APP;

Associating the usage characteristic variable with the corresponding barcode to construct a barcode classification function;

Extract the current use feature variables when the barcode is being used through the APP;

Based on the currently used characteristic variable, use the barcode classification function to generate a barcode classification result, the barcode classification result including a barcode corresponding to the currently used characteristic variable; and

The barcode corresponding to the currently used characteristic variable is automatically displayed in the APP.

Preferably, the APP includes two or more barcodes, and the barcodes are two-dimensional codes or barcodes. Those skilled in the art can understand that the barcode can also be other suitable digital codes. For example, the APP may be an APP with a coupon function such as Alipay, which may include a bus ride code (two-dimensional code or barcode), a subway ride code (two-dimensional code or barcode), and other barcodes.

Preferably, the barcode display method may further include using a processor to execute the following processing actions:

Acquiring the first usage characteristic variable when the first barcode is used through the APP;

Associating the first usage characteristic variable with the first barcode;

Acquiring a second usage characteristic variable when the second barcode is used through the APP, wherein the second usage characteristic variable is different from the first usage characteristic variable;

Determine whether the second barcode is the same as the first barcode;

If yes, also associate the second usage characteristic variable with the first barcode;

Otherwise, the second usage characteristic variable is associated with the second barcode.

In this way, as the user continues to use the barcode of the APP (for example, to make a payment), a barcode classification function for the APP is constructed.

Preferably, the use characteristic variable includes characteristic information related to the use of the barcode generated when the barcode is used, and preferably includes the date, time and location of the use of the barcode. In the scenario of using barcodes for payment, the use characteristic variables include the date, time and place of payment. Those skilled in the art can understand that other usage characteristic variables that help payment classification are also possible. Since the payment application APP is installed on a terminal such as a mobile phone, the date, time and place of payment can be obtained, for example, through a timer and GPS on the mobile phone.

Preferably, the barcode display method further includes: comparing the current use characteristic variable with the respective use characteristic variable of each barcode, and the payment classification function generates a use characteristic variable similar to the current use characteristic variable. The corresponding barcode.

Preferably, comparing the current use characteristic variable with the respective use characteristic variable of each barcode includes calculating the distance between the current use characteristic variable and the respective use characteristic variable of each barcode. The payment classification function generates a barcode corresponding to the use characteristic variable closest to the current use characteristic variable.

A barcode display device according to an embodiment of the second aspect of the present invention includes:

The acquisition module is used to extract the characteristic variables used when using the barcode through the application APP;

The classification function construction module is used for associating the use characteristic variable with the corresponding barcode to construct a barcode classification function;

The extraction module is used to extract the current use feature variables when the barcode is being used through the APP;

A determination module, configured to generate a barcode classification result using the barcode classification function based on the currently used characteristic variable, the barcode classification result including a barcode corresponding to the currently used characteristic variable; and

The display module is used to automatically display the barcode corresponding to the currently used characteristic variable in the APP.

A barcode display device according to an embodiment of the third aspect of the present invention includes: a processor; and a memory on which executable instructions are stored, wherein the executable instructions when executed cause the processor to execute The aforementioned bar code display method.

A machine-readable storage medium according to an embodiment of the fourth aspect of the present invention has executable instructions stored thereon, wherein the executable instructions, when executed, cause a machine to execute the aforementioned bar code display method.

It can be seen from the above that the barcode display solution of the above embodiment of the present invention, by learning the classification function of the relationship between the user’s behavior of using the barcode and the relationship between the scene factors and the use result, calculates and decides the barcode that the user is most likely to use in real time in the use scene . The technical effect that this solution can achieve is: when users use barcodes, card package apps can directly display the barcodes that best fit the current scenario, provide users with a good experience, and help APP improve customer retention.

The embodiment of the present invention proposes a bar code display method, equipment and device based on user behavior learning, which can help card package apps to make quick decisions and display bar codes that users may use when using them, so as to provide users with good use Experience.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 shows an overall flowchart of a barcode display method 100 according to an embodiment of the present invention. The method 100 may be executed by a server or one or more processors.

As shown in FIG. 1, in step 110, through, for example, a server or a processor, a use characteristic variable when using a barcode through an application program APP is obtained.

In one embodiment, the use characteristic variable includes characteristic information related to the use of the barcode generated when the barcode is used, and preferably includes the date, time and location of the use of the barcode. In the scenario of using barcodes for payment, the use characteristic variables refer to payment-related characteristic information generated during payment, such as the date, time and/or place of payment. Those skilled in the art can understand that other usage characteristic variables that help payment classification are also possible. Since the payment application APP is installed on a terminal such as a mobile phone, the date, time and place of payment can be obtained through GPS and online networks on the mobile phone, for example. For example, when a user uses a certain payment APP to make a payment through a barcode such as a QR code or a barcode, the date, time and/or location of the payment are automatically recorded through the GPS on the mobile phone and the online network.

The technical carriers involved in payment in the embodiments of this application may include, for example, Near Field Communication (NFC), WIFI, 3G/4G/5G, POS machine card swiping technology, QR code scanning technology, and barcode scanning technology. Technology, Bluetooth, infrared, Short Message Service (SMS), Multimedia Message Service (MMS), etc.

In step 120, the use characteristic variable is associated with the corresponding barcode through, for example, a server or a processor, to construct a barcode classification function.

According to one embodiment, the payment APP includes two or more barcodes, and the barcodes are two-dimensional codes or barcodes. Those skilled in the art can understand that the barcode can also be other suitable digital codes. For example, the APP may be an APP with a coupon function such as Alipay, which may include a bus ride code (two-dimensional code or barcode), a subway ride code (two-dimensional code or barcode), and other barcodes.

Fig. 2 shows an overall flowchart of a barcode classification method 200 according to an embodiment of the present invention. The method 200 may be executed by a server or one or more processors.

Continuing to refer to FIG. 1 and referring to FIG. 2, in step 210, the first use characteristic variable when the first barcode (for example, payment) is used through the APP is extracted through, for example, a server or a processor. For example, a user pays for a bus ride near a bus stop at 8:15 on a Monday morning. In this example, the first usage characteristic variable may include Monday, 8:15 AM, and bus station.

In step 220, the first usage characteristic variable is associated with the first barcode through, for example, a server or a processor. In the above example, the first barcode may be a bus boarding code (two-dimensional code or barcode). Therefore, through the processor, for example, "Monday", "8:15 AM", and "Bus Stop" are associated with the "Bus Boarding Code".

In step 230, using, for example, a server or a processor, extract a second usage characteristic variable when the second barcode (for example, payment) is used through the APP, where the second usage characteristic variable is different from the first usage characteristic variable. For example, a user uses a subway transit code to pay for a subway ride near a subway station at 9:00 on Monday morning. The second usage characteristic variable may include Monday, 9:00 AM, and subway.

In step 240, it is determined whether the second barcode is the same as the first barcode through, for example, a server or a processor. For example, the processor determines whether the subway boarding code as the second barcode is the same as the bus boarding code as the first barcode.

In step 250, through, for example, a server or a processor, if yes, the second usage characteristic variable is also associated with the first barcode. For example, suppose that the user uses a bus code to pay for another bus at 8:30 on Monday morning near another bus stop. In this case, through, for example, the processor, "Monday", "8:30 AM", and "another bus stop" can be associated with the "bus boarding code".

In step 260, through, for example, a server or a processor, otherwise, the second usage characteristic variable is associated with the second barcode. In the above example, the second barcode may be a subway ride code (a two-dimensional code or a barcode), and thus is different from the first barcode (ie, a bus ride code). Therefore, through the processor, for example, "Monday", "9:00 AM", and "Metro" are associated with "Metro boarding code".

Those skilled in the art can understand that users may first take a bus and then take the subway to work during normal working days from Monday to Friday. Thus, the date in the use feature variable may be "Monday", "Tuesday", "Wednesday", "Thursday", and "Friday". In addition, if the user's living habits are relatively regular, the location in the use feature variable can be omitted. That is, it is only necessary to associate the date and time in the use characteristic variable with the corresponding barcode. In addition, those skilled in the art can also understand that the user using the barcode to pay through the APP near the bus station may be to use the bus transit code to pay for the bus, or the user may use the barcode to make payment through the APP near the subway station. To use the subway transit code to pay for the subway. Therefore, the date and time in the use characteristic variable can be omitted, and only the location in the use characteristic variable is associated with the corresponding barcode.

Although the description above refers to taking transportation, those skilled in the art should be able to understand other application scenarios. For example, use McDonald’s coupons to order breakfast at 7:30 in the morning on a working day, and at noon on a working day. Use Ele.me coupons to order lunch in the company at 12:00, etc.

In step 270, a barcode classification function is constructed by associating the first and second usage characteristic variables with the corresponding (first or second) barcode through, for example, a server or a processor. The barcode classification function can determine the corresponding barcode according to the input usage characteristic variables.

Continuing to refer to FIG. 1, in step 130, through, for example, a server or a processor, the current use characteristic variable when the barcode is being used by the APP is extracted. For example, when the user takes out the mobile phone to make payment through the APP, the date, time and/or location when the user is using the barcode can be obtained through the GPS and online network on the mobile phone.

In step 140, a barcode classification result is generated based on the currently used characteristic variable and the aforementioned barcode classification function through, for example, a server or a processor, and the barcode classification result includes a barcode corresponding to the currently used characteristic variable.

In an embodiment, the barcode display method further includes comparing the currently used characteristic variable with the respective use characteristic variable of each barcode with the aid of the barcode classification function, and outputting similar to the currently used characteristic variable Use the barcode corresponding to the characteristic variable.

More specifically, the barcode display method further includes calculating the distance between the currently used characteristic variable and the respective use characteristic variable of each barcode by means of the barcode classification function, and outputting the distance from the currently used characteristic variable The barcode corresponding to the most recently used feature variable. For example, the user opens the payment app at a subway station at 9:5 a.m. next Monday. In this case, the currently used characteristic variables may include "Monday", "9:5 AM" and "Iron Station". Therefore, according to the embodiment of the present invention, the currently used feature variables ("Monday", "9:5 AM", and "Subway Station") can be respectively used with the corresponding service feature variables ("week of the week" One", "8:15 AM" and "Bus Stop") and the corresponding characteristic variables ("Monday", "9:00 AM" and "Subway") corresponding to the subway boarding code are compared. It can be seen that the date ("Monday") of the current use of the feature variable is the same as the date corresponding to the bus boarding code and the subway boarding code; and the location of the current use of the feature variable ("Metro") is the same as that of the subway. The location corresponding to the bus code is the same. Preferably, the distance between the corresponding use feature variables can be calculated. For example, the distance between the time of the currently used feature variable ("9:5 AM") and the time corresponding to the subway boarding code ("9:00 AM") is less than the time corresponding to the bus boarding code ("8:15 AM") distance between them. Therefore, according to the above example, the current use feature variable is more similar to the corresponding use feature variable when the user uses the subway ride code. Therefore, the barcode classification function can be based on the currently used feature variable ("Monday", " "9:5 AM" and "Metro Station") output the subway boarding code.

In step 150, the barcode corresponding to the currently used characteristic variable is automatically displayed in the APP through, for example, a server or a processor. In the above example, for the currently used feature variables ("Monday", "9:5 AM", and "Metro station"), the payment APP automatically displays the subway boarding code to facilitate the user to take the subway.

In another example, the barcode classification function can output the bus boarding code based on "Tuesday", "8:20 AM", and "Bus Stop" as the currently used feature variables, and pass it when the user pulls out his mobile phone The APP automatically displays the bus code when making a payment. In another example, the user takes out his mobile phone near a subway station at 3 o'clock on Sunday afternoon to open a payment app. In this case, according to the teaching of the present invention, the barcode classification function can output the subway boarding code mainly based on the location ("subway station") that is the currently used feature variable. Therefore, according to the present invention, the barcode classification function can be set with different weights for different usage characteristic variables. For example, the weight of "location" in the feature variable is greater than the weight of "time", which is greater than the weight of "date".

Preferably, each time the barcode is used, the barcode used and its corresponding use characteristic variables will be "learned", so as to perfect the barcode classification function constructed.
