Description

Traffic payment method and device

Technical field

The present application relates to the field of near field communication (English: Near Field Communication, abbreviation: NFC), and particularly relates to a method and device for payment of traffic.

Background technique

Near Field Communication NFC is a wireless connection technology that uses electromagnetic induction to realize short-range communication between electronic devices. The working mode of NFC includes card simulation mode (English: Card Emulation, abbreviation: CE). With the popularization of NFC technology, the number of NFC-enabled terminals (referred to as NFC terminals) is increasing. NFC terminals work in card emulation mode, simulating traffic cards and financial contactless integrated circuits (English: Integrated Circuit, Abbreviation: IC) card has become an important application scenario for NFC terminals to be used for payment. Users can use the NFC terminal to simulate a transportation card to take the bus, or use the NFC terminal to simulate a financial IC card, and use the mobile phone to checkout with a non-contact POS machine.

Taking the NFC terminal simulation traffic card as an example, for the segmented toll system public transportation system (such as the subway), the more common analog transportation card application payment method is to brush the card once and for all. The specific implementation is:

When the user swipes the analog traffic card to the station, the contactless card reader (such as the gate) selects the traffic card application in the simulated traffic card, reads the subway application data file in the simulated traffic card, specifically, the contactless card reader sends READ CAPP DATA command and receive response message returned by the simulated traffic card. The contactless card reader determines whether the last transaction was successful according to the data recorded in the subway application data file, and if the transaction is successful, sends an acquisition processing option including a transaction amount of 0 to the simulated transportation card (English: Get Processing Option, abbreviation :GPO) instruction. After that, the contactless card reader writes the inbound information into the subway application data file by using the write application data file command, updates the subway charge special data record, fills in the city code, the operation enterprise code, the record format version number, the transaction flag, and the charge. Area trading time, toll area transaction line code, toll area transaction site code, toll area transaction gate code, toll area transaction serial number and dedicated tracking area code (English: Tracking Area Code, abbreviation: TAC), etc. And write the location of the information related to the charging area. After completing the above operation The rear station gate opens and the user enters the station.

When exiting the station, the contactless card reader first reads the subway application data file in the simulated traffic card, and according to the data record of the application file, determines whether the charging area is normally entered in the last time; if it is normal, it calculates according to the inbound information. The amount is consumed and a transaction order GPO containing the transaction amount is sent; after that, the contactless reader writes outbound information to the subway application data file. Specifically, the contactless card reader has obtained an inbound record by reading the READ CAPP DATA command, and according to the record, the subway charge special data record is updated, and the toll area transaction time and the toll area transaction line are filled out. Code, transaction area code of the toll area, code of the transaction area of the toll area, transaction amount of the toll area, transaction number of the toll area, special TAC, etc., and retain the city code, operation enterprise code, record format version number, transaction mark Enter the original value in the fields of the toll area transaction time, the toll area transaction line code, the toll area transaction site code, the toll area transaction gate code, the toll area transaction serial number, etc., and finally record the record in the simulated transportation card. Complete the simulation of traffic card side billing and user outbound.

In the above-mentioned process of using the simulated traffic card application to realize the transportation payment, when at least two people travel together on the segment-based toll system, if the passenger cannot reach a simulated traffic card, the passenger needs to queue up for a long time to purchase the card. Buying a ticket for change, resulting in inconvenient travel or even a ride, the user experience is poor.

Summary of the invention

detailed description

The present invention will be further described in detail with reference to the accompanying drawings, in which FIG. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

In view of the problem that the prior art utilizes the simulated traffic card application to realize the transportation payment, the problem that at least two people share the same simulated traffic card entry and exit station cannot be realized. The embodiment of the present application provides a transportation payment method and device, by changing the transportation card. The business logic can realize one card and more brushes, and two or more people can use the same traffic card to enter and exit the station.

The embodiment of the present application can be applied to a scenario of card payment, and is preferably applied to a mobile payment scenario. The traffic card involved is a traffic card simulated by a terminal device such as a mobile phone or a tablet computer, and is carried in a terminal having an NFC function. The system architecture applied in the embodiment of the present application is as shown in FIG. 1, and includes a terminal 101 and a charging device 102. The terminal 101 is provided with an NFC function and may include various handheld devices having wireless communication functions, wearable devices, computing devices, or other processing devices connected to the wireless modem. Ready, for example, NFC-enabled mobile phones, tablets. The terminal 101 includes a main controller (English: Device Host, abbreviated as DH). For example, if the terminal is a mobile phone, the DH is a central processing unit (English: Central Processing Unit, abbreviated as CPU). The billing device 102 is used for deducting the traffic card application in the public transportation system, and may be a bus in-vehicle charging machine (also called an in-vehicle device); the charging device 102 may be applied to a segment-charging vehicle, for example Buses, subways, ships, etc. The charging device 102 can also be applied to a charging scenario with a time-slot charging, such as a parking charging scenario, the transportation card is a parking card, and the charging device 102 is configured to charge the parking card in the parking system by time.

Based on the system architecture shown in FIG. 1, the traffic payment method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

Referring to FIG. 2, the flow of the payment payment method provided by the embodiment of the present application is as follows.

In the following description, the terminal has an NFC function, and the terminal has built-in software and hardware capable of simulating a traffic card (referred to as a traffic card), and the terminal communicates with the charging device through the NFC, and performs a charging deduction through the simulated traffic card and the charging device.

Step 201: The terminal determines the number N, N of the number of people who need to make traffic payment, and is a natural number greater than 1.

Step 202: The terminal and the first charging device perform M times of inbound authentication, and generate M charging data records, where M is a natural number greater than 1 and less than or equal to N.

Step 203: The terminal and the second charging device perform M outbound authentication.

The above steps 201 to 203 will be described in detail below.

Specifically, the traffic card management application can be run in the operating system of the terminal (English: Operating System, abbreviated as OS), and the user can perform some basic settings and management on the traffic card in the traffic card management application. In step 201, when the user uses the traffic card application of the terminal, the user can input the number of people who need to make traffic payment in the interface of the traffic card management application in the OS, and the terminal detects the input operation of the user, and determines that the traffic payment needs to be performed this time. Number of people N.

Of course, the number N of people who need to make a traffic payment at the terminal can be different from the number M of the actual station. For example, the number of people who need to make traffic payment detected by the terminal is 5, but The number of intervening stations is 4.

Optionally, the terminal may also detect traffic interval information input by the user, that is, the inbound information and the outbound information.

After step 201, before step 202, the terminal determines whether the current balance of the traffic card is sufficient to pay the amount of the N-person current payment. The specific method is: the terminal determines whether the current balance of the traffic card is greater than or equal to the product of the highest single limit and N, and if so, determines that the current balance of the traffic card is sufficient; otherwise, it determines that the current balance of the traffic card is insufficient. Alternatively, if the terminal detects the traffic section information input by the user, calculating the traffic payment amount of the single person in the traffic section, and the terminal determining whether the current amount of the traffic card is greater than or equal to the product of the traffic payment amount of the single person in the traffic section and N, If yes, it is determined that the current balance of the transportation card is sufficient; otherwise, it is determined that the current balance of the transportation card is insufficient.

In the case that it is determined that the current balance of the transportation card is sufficient, step 202 is performed.

A terminal with NFC capability has the property that a data record is saved each time a complete inbound and outbound authentication is performed. The data record records the inbound information, outbound information, and deduction amount of the current transportation payment.

Prior to execution of step 202, a data record generated by the historical transaction process may have been saved in the terminal. In step 202,

In step 202, an inbound authentication is triggered each time the terminal is placed within the communication range of the first charging device, that is, whenever the terminal can communicate with the first charging device via NFC. Each time the terminal performs the inbound authentication, the terminal sends a complete data record of the history record to the first charging device, and the first charging device determines whether the last transaction of the terminal is successful through the received data record, and determines the transaction. If successful, the inbound authentication will be successful. Otherwise, the inbound authentication fails. The data record sent by the terminal to the first charging device may include information indicating that the traffic payment function is normal. A special case is that if the terminal does not have a historical transaction process before step 202, but the card balance is sufficient, and the last wrong transaction is not found, it may be a newly installed traffic card application of the terminal. In this case, The data record sent by the terminal to the first charging device may be a special data record, for example, the data record of the inbound information and the outbound information are empty, and the special data record is used as the traffic card for the traffic payment function. Instructions.

After the terminal sends the information indicating that the traffic payment function is normal to the first charging device, the first charging device returns a response message, which is recorded as a first response message, and the first response message is used to indicate that the inbound authentication is successful, and the The first response message includes inbound related information, such as the station name of the inbound station, the starting transaction amount, etc., and the starting transaction amount may be 0. After receiving the first response message returned by the first charging device, the terminal generates a charging data record based on the inbound related information included in the first response message, and the charging data is recorded after the historically saved data record. In this way, after performing the M times of the inbound authentication, the terminal generates M charging data records, and the inbound related information included in each of the charging data records of the M charging data records is the same, that is, The M station is the same station.

In step 203, an outbound authentication is triggered each time the terminal is placed within the communication range of the second charging device. When the terminal triggers the outbound authentication, the terminal needs to send a charging data record including the inbound related information to the second charging device, and the second charging device determines whether the terminal normally enters the station, and determines that the terminal normally enters the station. The outbound authentication will be executed successfully. Otherwise, the outbound authentication fails. Specifically, each time the terminal triggers the outbound authentication, the terminal sends a charging data record generated during the inbound authentication to the second charging device, because the inbound related information included in the M charging data records is the same, The charging data records sent by the terminal at each outbound authentication may be in any order, for example, may be selected from the first to the Mth.

Specifically, each time the outbound authentication is performed, the terminal selects one charging data record in the M charging data records according to the setting order, and sends the selected one charging data record to the second charging device. After receiving the charging data record, the second charging device determines that the terminal normally enters the station, and constructs a complete transaction data record including the inbound related information, the outbound related information, and the deduction amount, and records the complete transaction data. Writing to the card application of the terminal; or, after receiving the charging data record, the second charging device determines that the terminal normally enters the station, and returns a response message indicating that the outbound success is successful to the terminal, which is recorded as the second response message. . Optionally, the outbound related information, such as the station name and the transaction amount of the outbound, may be carried in the second response message. After receiving the second response message sent by the second charging device, the terminal adds the outbound related information included in the second response message to the corresponding charging data record, and generates a piece of information including the inbound related information and the outbound related information. Complete transaction data record. And finally The terminal performs the license transaction process according to the transaction amount included in the second response message, that is, the deduction is performed according to the transaction amount included in the second response message.

Optionally, the information of the terminal maintenance counter, that is, the terminal starts the counter after determining the number N of people who need to make the traffic payment, and performs one inbound authentication or each second charging device with each first charging device. The number of people who have passed is recorded or updated when an outbound authentication is performed. In this way, it is avoided that the actual number of inbounds exceeds the number of inbounds N set by the terminal, resulting in a transaction error.

Specifically, the initial value of the counter is set to zero. The terminal and the first charging device determine that the counter value is less than or equal to (M-1) before transmitting the saved information indicating that the traffic payment function is normal to the first charging device in the process of performing the inbound authentication. And greater than 0; and, after each completion of the inbound authentication, the counter is incremented by one;

The terminal and the second charging device determine that the counter value is less than or equal to (2M-1) before sending the selected charging data record to the second charging device in each process of performing the outbound authentication; And, after each completion of the outbound authentication, the counter value is incremented by one.

Optionally, the terminal may further maintain the latest data record location indication information (which may be simply referred to as location indication information), and indicate, by using the location indication information, a location where the information sent to the first charging device or the second charging device is located. That is, each time the inbound authentication is performed with the first charging device or the outbound authentication is performed with the second charging device, the terminal determines the location of the transmitted information according to the location indicated by the location indication information.

Wherein, when the terminal and the first charging device perform the first to (M-1)th inbound authentication, after each completion of the inbound authentication, the location indicated by the latest data recording location indication information is kept unchanged, In order to point to the location where the traffic is functioning properly. After performing the Mth inbound authentication, the location indicated by the latest data record location indication information is changed to the location of the charging data record generated when the first inbound authentication is performed;

When the terminal and the second charging device perform the first to (M-1)th outbound authentication, after each completion of the outbound authentication, the location indicated by the latest data recording location indication information is respectively changed to be executed. The location of the billing data record generated during the second to the Mth inbound authentication.

Optionally, in the case of M<N, since the number of inbounds initially detected by the terminal is N, then In this case, the terminal can determine the number of people who ultimately need to enter the station by:

After the terminal performs the Mth inbound authentication, if the terminal does not perform the (M+1)th inbound authentication after the terminal has passed the set time threshold, the number of people who need to make the traffic payment is adjusted from N to M.

Based on the foregoing embodiments, the traffic payment method provided by the embodiment of the present application is further described in detail below in conjunction with a specific application scenario.

Assuming that the terminal is a mobile phone, the mobile phone has an NFC function, and an application program of a simulated transportation card (referred to as a transportation card) is installed in the mobile phone, and a traffic card management application for managing the transportation card is installed, and the transportation card management application performs the traffic card. Some basic settings and management. The application scenario is the charging system of the subway in and out station. The first charging device and the second charging device are the gates in the subway, which are respectively the inbound gate and the outbound gate.

As shown in FIG. 3, in the subway inbound and outbound charging system, the flow of the mobile phone to realize multi-person simultaneous inbound is as follows.

Step 301: The user opens the mobile phone, and switches the mobile phone interface to the traffic card management application interface, and selects the number N (N=2, 3, 4, . . . ) at the same time.

Optionally, you can also enter the ride interval. The N value is not higher than the maximum number of passengers defined by the bus company. The bus card management application is an application in the mobile phone OS.

Step 302: The mobile phone determines whether N people are allowed to ride at the same time.

Specifically, after receiving the number N of the user input, the traffic card management application in the mobile phone starts to perform a policy check to determine whether the current balance of the traffic card simulated by the mobile phone supports the N-person ride; specifically, the traffic card management application queries the traffic card. The current balance, if (balance + segment deduction deduction limit) is greater than or equal to (N* maximum single occupancy limit), or if (balance + segment deduction deduction limit) is greater than or equal to (N * user input ride interval Corresponding to the fare), step 303 is performed; otherwise, step 303' is performed.

Step 303, allowing the N people to ride at the same time.

Specifically, the number of simultaneous passengers N is transmitted to the traffic card application, and the counter is initialized and the latest data recording position indication information (referred to as position indication information) is initialized. The data record can be a dedicated data record for the subway charge.

The traffic card management application configures the traffic card and writes the number of passengers N simultaneously into the "simple passenger limit" field in the traffic card application. The counter is used to record the number of inbounds and the number of outbounds. The traffic card management application configures the initial value of the counter to zero. The initial value of the position indication information is set at the position of the data record generated by the most recent transaction. Specifically, the location indication information may be set in the form of a “latest data record pointer”, which is a pointer to a subway charging dedicated data record that successfully completed the transaction last time, or reads a subway charging dedicated data record corresponding to the last successful transaction. ID of the ID.

Assuming that m+1 subway ride records have been saved in the traffic card, the traffic card management application after the traffic card is configured, the data record files in the traffic card are as shown in Table 1 below.

Table 1

R_m R _m	进站信息Inbound information	出站信息Outbound information	位置指示信息Location indication
R_m-1 R _m-1	进站信息Inbound information	出站信息Outbound information	————
……......	……......	……......	————
R₀ R ₀	进站信息Inbound information	出站信息Outbound information	————

Table 1 and "-" in the following tables indicate that the data record corresponding to the row is not set with "position indication information", and the field labeled "location indication information" indicates the data record setting "position indication information" corresponding to the row. . The fields of "-" and "location indication information" can be designed in the form of yes/no (ie true/false or yes/no). R ₀ to Rm are used to indicate the label of the data record, and Rm corresponding to the row where the position indication information is located is the latest data record.

In step 303', the mobile phone prompts the user that the balance in the traffic card is insufficient or the status of the traffic card is abnormal.

Step 304: Swipe the card, check whether the number of inbounds in the mobile phone is less than (N-1), and if yes, go to step 305; otherwise, go to step 306.

Whether the value of the traffic card check counter is less than (N-1), for example, N=5, and whether the value of the traffic card check counter is less than 4.

Step 305: The traffic card in the mobile phone responds according to the latest data record indicated by the location indication information. Inbound gate, increment the counter value by one and return to step 304.

When the first card is put in, the counter value is 0, the Rm corresponding to the position indication information is the latest data record, and the traffic card in the mobile phone is sent to the inbound gate according to the data record corresponding to Rm. After the first person enters the station, the value of the counter is incremented by 1 to become 1. The counter value is incremented by 1 each time the second to the (N-1)th time is swiped, but the latest data record indicated by the position indication remains unchanged and remains at R _m .

Step 306: Swipe the card, check whether the number of inbounds in the mobile phone is equal to (N-1), and if yes, go to step 307; otherwise, go to step 309.

Step 307: The traffic card in the mobile phone responds to the inbound gate according to the latest data record indicated by the position indication information, and increments the counter value by one.

Step 308: Update the latest data record indicated by the location indication information to the data record generated when the first person enters the station.

Step 309: Perform an outbound process.

Taking the first swipe into the station as an example, the above steps are illustrated. When the user first uses the traffic card in the mobile phone to swipe the station, in the inbound processing flow, the inbound gate sends a read application data file (ie READ CAPP DATA) command to read the CAPP file to determine whether the transaction was successful last time. When the traffic card receives this command, it performs the check of the number of people who have entered the station. If the value of the counter of the traffic card is less than or equal to (N-1), it is determined that the traffic card is in the multi-person inbound mode; the latest data record pointer in step 303 is used. The pointed data record is replied to the inbound gate, or the subway charging data record pointed to by the latest subway charging dedicated data record is recorded in response to the inbound gate; the indicia of the plurality of inbound data records may be consecutive integers.

After receiving the response, the inbound gate determines that the traffic card last transaction is normal, sends a GPO with an authorized amount of 0, and the traffic card receives the GPO response message after receiving the GPO;

After receiving the response message of the GPO, the gate of the inbound gate determines that the last transaction is successful, enters the segmentation charging process; and uses the UPDATA CAPP DATA CACHE command to update the traffic information to the traffic card, specifically to the traffic Write a new subway charge-specific data record in the card, package Includes inbound information and default outbound information.

After the first person swipes in the station, the data record file update in the traffic card is as shown in Table 2.

Table 2

……......	……......	……......	……......
R₀ R ₀	进站信息Inbound information	出站信息Outbound information	————

The "NULL" indication in Table 2 and the following table is empty. It can be seen from Table 2 that after the first person swipes in the station, an inbound record is added to the data record file in the traffic card, but the location of the latest data record indicated by the latest position indication information remains unchanged, meaning In the next card swipe, the gate will still be answered with the record R _m .

Optionally, when the Nth card is swiped, that is, the Nth person enters the station to swipe the card, the user can prompt the last person to enter the station through the mobile phone interface.

When the Nth person swipes into the station, the value of the counter is (N-1), and the value of the traffic card check counter is less than (N-1), step 306 is performed.

After the Nth person swipes into the station, the traffic card modification position indication information points to Rm+1, so that the Rm+1 transaction record becomes the latest data record, and the data record file in the traffic card is as shown in Table 3.

table 3

……......	……......	……......	……......
R₀ R ₀	进站信息Inbound information	出站信息Outbound information	————

It can be seen from Table 3 that after N people have entered the station, the position indication information points to the data record generated when the first person enters the station, which means that the next time the card is swiped, only the Rm+ of the inbound information will be included. One data record answers the gate, triggering an outbound settlement.

It is worth noting that the traffic card judges the working mode of the traffic card according to the counter that indicates the number of people who have entered the station. When 0<= counter <=N-1, it is the multi-person card inbound mode.

Multiple users must be on the same bus, so when the traffic card receives the update card application data file command, it checks the inbound information in the data record containing only the inbound information in the application data file, and the update card application data file command. Whether the inbound information is consistent; if it is inconsistent, an error is reported and the card application is set to the abnormal mode.

In order to prevent the actual number of inbound calls from being less than the set number of passengers at the same time, the traffic card preset time threshold T, after exceeding T, the electronic card automatically calculates the number of inbound information in the current card, and updates the position indication information. The data record points to the first inbound record.

Based on the method flow shown in FIG. 3, referring to FIG. 4, the signaling flow of the inbound authentication is as follows.

The first inbound authentication signaling process is:

S401. The inbound gate sends a READ CAPP DATA command to the mobile phone, and the mobile phone receives the READ CAPP DATA command sent by the inbound gate, reads the CAPP file, determines the inbound mode of the traffic card, and prepares for the response.

S402: The mobile phone returns a response message to the inbound gate, and the response message includes the Rm data record.

S403. The inbound gate sends a UPDATA CAPP DATA CACHE command to the mobile phone to update the traffic information to the traffic card, and writes the Rm+1 data record in the data record file of the traffic card.

S404. The mobile phone returns a response message to the inbound gate.

The second to Nth inbound authentication signaling process is similar to the first inbound authentication signaling process, only In the step S403, the data records of the Rm+2 to Rm+n are sequentially written, n=N.

As shown in FIG. 5, in the subway inbound and outbound charging system, the flow of the mobile phone to realize multi-person simultaneous outbound is as follows.

Step 501: The user holds the mobile phone to swipe the card at the exit, and the traffic card receives the READ CAPP DATA command to obtain the information of “the number of simultaneous riders N” and the “count of used times”.

Step 502: Determine whether the counter value is greater than or equal to N and less than or equal to 2N-1. If yes, execute step 503, otherwise perform step 504.

Step 503, the traffic card can determine that the current multi-person outbound mode; the data record pointed to by the latest data record pointer (that is, the first inbound record) is answered by the inbound gate, or the latest subway charging dedicated data record mark is utilized. The subway charging data record pointed to the inbound gate.

Step 503', the traffic card can determine that the current mode is single player.

Step 504: The gate receives the READ CAPP DATA response message, reads the inbound information to determine the normal inbound, starts to execute the gate billing process, uses the GPO to send the transaction instruction to the traffic card, and the traffic card should perform the outbound process license transaction;

Step 505: The gate uses the inbound data record included in the response obtained by the READ CAPP DATA to generate a complete data record including the inbound and outbound information and the transaction amount, and writes the complete data to the traffic card by using the UPDATE CAPP DATA CACHE command. Record; after receiving the command, the transportation card saves the complete data record to the terrain application data file CAPP, and updates the "new subway charge special data record mark" to point to the next inbound data record; at the same time, the counter is incremented by one; After the individual leaves the station, the charge record file in the card is shown in Table 4.

Step 506: When the card is swiped again, it is determined whether the value of the counter is equal to 2N-1. If not, the process returns to step 501 to continue to swipe the card out; after each card is sent out, the position indication information is moved. The position of the latest data record; if it is determined that the value of the counter is equal to 2N-1, step 507 is performed.

In step 507, when the counter value is 2N-1, the last person is prompted to leave the station through the mobile phone interface. The traffic card automatically restores the "simple occupancy limit N" to 1, and restores the inbound and outbound processing to single-person mode, that is, single-use status.

In single-player mode, N and counters are no longer checked during use, the counter value is reset to zero, and the latest subway charge-specific data record points to the latest transaction record.

After the above Nth person exits the station, the data record file in the traffic card is shown in Table 5.

Based on the method flow shown in FIG. 5, referring to FIG. 6, the signaling flow of the outbound authentication is as follows.

S601, the outbound gate sends a READ CAPP DATA command to the mobile phone, and the mobile phone receives the READ CAPP DATA command sent by the outbound gate, reads the CAPP file, determines that the traffic card is in the outbound mode, and prepares for the response.

S602. The mobile phone returns a response message to the outbound gate, and the response message includes the Rm+1 data record, and the Rm+1 data record is an inbound record containing only the inbound information.

S603. The outbound gate sends a UPDATA CAPP DATA CACHE command to the mobile phone to update the outbound information to the traffic card, and writes the Rm+1 data record including the outbound information in the data record file of the traffic card.

S604. The mobile phone returns a response message to the outbound gate.

The second to the Nth outbound authentication signaling flow is similar to the first outbound authentication signaling flow, except that the first Rm+2 to Rm+n, n=N are sequentially written in the step S603, and each data record is recorded. The corresponding outbound information is written in the middle.
