[0060] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0061] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0062] The main solution of the embodiment of the present application is: to detect the area where the target passenger is located through the UWB radio frequency module, the area where the target passenger is located includes a preset authentication area, a card reading area or a card writing area; and to perform corresponding interactive operations based on the area where the target passenger is located.

[0063] The features of the existing general UWB gate payment software processing solutions are as follows (1) to (5):

[0064] (1) Based on the existing gate NFC payment process.

[0065] (2) UWB is a new payment medium and is connected to the gate reader in the form of a payment channel module.

[0066] (3) The payment process uses the same instructions as the original NFC payment.

[0067] (4) The original instruction passed to the NFC channel is passed to the UWB module, and the response data is received to complete the entire payment.

[0068] (5) The entire process is initiated by the gate machine and executed sequentially.

[0069] Reference Figure 1 , Figure 1 Schematic diagram of UWB payment processing flow in general mode.

[0070] The UWB payment processing flow in general mode is as described in A1~A22 below:

[0071] A1, the gate starts searching for the card.

[0072] A2: The large reader receives the card and initiates the UWB RF module to check whether there is a UWB tag in the transaction area.

[0073] A3, if a UWB tag is detected, FiRa Authentication is initiated. After successful authentication, the tag's MAC address and positioning coordinates are returned to the large reader.

[0074] A4, after receiving the response, the large reader returns a successful card search response to the gate.

[0075] A5, after the gate receives the MAC address of the response tag, it initiates a transaction instruction to the large reader.

[0076] A6, after receiving the transaction instruction, the large reader sends an application selection instruction to the UWB radio module.

[0077] A7, the UWB radio module forwards the application selection command, obtains the response, and returns the response to the large reader.

[0078] A8, after receiving the response, the large reader continues to organize the read file 1 instruction and sends the read file 1 instruction to the UWB radio module.

[0079] A9, after receiving the transaction instruction, the large reader sends an application selection instruction to the UWB radio module.

[0080] A10, the UWB radio module forwards the read file 1 instruction, obtains the response, and returns the response to the large reader.

[0081] A11, the large reader checks whether it needs to continue reading the file. If it does, go to step 8 for execution. If not, go to the next step.

[0082] A12, the large reader organizes the wallet reading instructions and sends instructions to the UWB radio module.

[0083] A13, the UWB radio module forwards the wallet read instruction, obtains the response, and returns the response to the large reader.

[0084] A14, a large reader performs itinerary matching and fare calculation.

[0085] A15, the large reader organizes the transaction initialization instructions according to the result of the previous step and sends them to the UWB radio module.

[0086] A16, the UWB radio module forwards the transaction initialization instruction, obtains the response, and returns the response to the large reader.

[0087] A17, the large reader performs MAC1 calculation and verification after receiving the response.

[0088] A18, after successful verification, organizes the consumption transaction instruction and sends it to the UWB radio frequency module.

[0089] A19, the UWB radio module forwards the consumer transaction instruction, obtains the response, and returns the response to the large reader.

[0090] A20, the large reader performs MAC2 calculation and verification after obtaining the response.

[0091] A21, after successful verification, sends a transaction completion response to the gate.

[0092] A22, the gate ends the transaction after receiving the transaction completion response.

[0093] However, the UWB payment processing flow in the general mode has the following three defects:

[0094] 1. Each instruction must interact with the UWB module, which involves many interaction processes, many error points, and a low success rate.

[0095] 2. The communication field of UWB is much larger than that of NFC, and is easily affected by external factors (human body occlusion, metal occlusion, environment). The long interaction time leads to a high failure rate.

[0096] 3. Sequential execution: the transaction process is initiated by the gate, which has low execution efficiency. It is not suitable for multi-tag gate processing.

[0097] Therefore, the present application provides a solution, which actively detects the target passenger through the UWB radio frequency module, determines that the area where the target passenger is located is a preset authentication area, a preset card reading area or a preset card writing area, and performs corresponding interactive operations based on the area where the target passenger is located. It can actively initiate UWB authentication, UWB card reading or UWB card writing functions, thereby improving processing efficiency and being suitable for quickly processing multi-user gate-passing scenarios.

[0098] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a travel interactive device, etc., or an electronic system capable of realizing the above functions, a rail transit system, etc. The following takes the rail transit system as an example to illustrate this embodiment and the following embodiments.

[0099] Based on this, the present application embodiment provides a travel interaction method, referring to Figure 2 , Figure 2 A flow chart of the first embodiment of the travel interaction method of the present application is provided.

[0100] In this embodiment, the travel interaction method is applied to a rail transit system, and the rail transit system includes an ultra-wideband UWB radio frequency module, including steps S10 to S20:

[0101] Step S10, detecting the area where the target passenger is located by using the UWB radio frequency module, where the area where the target passenger is located includes a preset authentication area, a card reading area or a card writing area;

[0102] Reference Figure 3 , Figure 3 Schematic diagram of the target passenger's card swiping behavior to enter the gate.

[0103] like Figure 3 As shown, when the target passenger enters between gates Gate1 and Gate2, he needs to pass through the authentication area, card reading area and card writing area. At this time, the UWB radio frequency module can be used to detect the area where the target passenger is located. The area where the target passenger is located includes the preset authentication area, card reading area or card writing area, wherein the preset authentication area, card reading area and card writing area can be customized and is not limited to Figure 3 as shown in .

[0104] Step S20, performing corresponding interactive operations based on the area where the target passenger is located.

[0105] Different interactive operations are performed in the authentication area, the card reading area and the card writing area.

[0106] This embodiment provides a travel interaction method, which actively detects the target passenger through a UWB radio frequency module, determines that the area where the target passenger is located is a preset authentication area, a preset card reading area or a preset card writing area, and performs corresponding interaction operations based on the area where the target passenger is located. UWB authentication, UWB card reading or UWB card writing functions can be actively initiated, thereby improving processing efficiency and being suitable for quickly processing multi-user gate-passing scenarios.

[0107] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. On this basis, step S20, performing corresponding interactive operations based on the area where the target passenger is located, also includes steps S21~S22:

[0108] Step S21, if it is detected that the target passenger enters the preset authentication area, the identity of the target passenger is authenticated by the UWB radio frequency module;

[0109] Step S22, if the identity authentication is successful, the target passenger associated tag carried by the target passenger is set to an authentication success state through the UWB radio frequency module, and the target passenger associated tag is added to a preset authentication success tag data queue.

[0110] Among them, passengers enter the authentication area, and passengers hold label products with UWB function to enter the UWB authentication area.

[0111] After the UWB radio frequency module detects that the target passenger has entered the authentication area, it starts the FiRa authentication process and establishes a secure transmission channel.

[0112] If the identity authentication is successful, the state of the tag with UWB function is set to the authentication success state, and the tag MAC address is added to the authentication success data queue.

[0113] This embodiment provides a travel interaction method, after the identity authentication is successful, the target passenger associated tag carried by the target passenger is set to the authentication success state and added to the preset authentication success tag data queue. This step ensures that only authenticated passengers can be identified and recorded by the system, effectively preventing unauthorized access and potential security risks.

[0114] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. On this basis, step S20, performing corresponding interactive operations based on the area where the target passenger is located, also includes steps S23 to S27:

[0115] Step S23, if the target passenger enters the preset card reading area, the UWB radio frequency module is used to check whether the target passenger associated tag is in the authentication successful tag data queue;

[0116] Among them, when the target passenger enters the card reading area, the UWB radio frequency module checks whether the tag with the MAC address is in the authentication success queue.

[0117] It should be noted that this step is to confirm whether the target passenger has completed identity authentication. Only when the target passenger's associated tag is in the authentication successful tag data queue, the system will continue to perform subsequent card reading operations.

[0118] Step S24: if not, constructing a comprehensive card reading data instruction packet through the UWB radio frequency module, and sending the comprehensive card reading data instruction packet to the target passenger associated tag;

[0119] Among them, if the associated tag of the target passenger is not in the data queue of the successfully authenticated tag, the system will construct a comprehensive card reading data instruction packet containing the information required for card reading through the UWB radio frequency module and send it to the associated tag of the target passenger.

[0120] As an implementation method, the integrated card reading data instruction packet may include a header, a data portion, and a tail portion. Each portion is explained below:

[0121] Header: The header usually contains basic information such as the type, length, and version number of the instruction packet, which is used to identify and parse the instruction packet.

[0122] Data part: The data part is the core of the instruction packet, which contains the specific information required for card reading. This information needs to be encoded in a specific format to ensure that the UWB radio module can parse it correctly.

[0123] Tail: The tail usually contains a checksum or terminator to verify the integrity and correctness of the instruction packet.

[0124] Step S25, receiving, through the UWB radio frequency module, a first response returned by the target passenger associated tag based on the integrated card reading data instruction packet;

[0125] Among them, after receiving the comprehensive card reading data instruction packet, the associated tag of the target passenger will return a response signal, indicating that the instruction has been received and is ready to perform the card reading operation.

[0126] Step S26, obtaining card reading data from the first response through the UWB radio frequency module, and adding the card reading data to a preset card reading success data queue;

[0127] The UWB radio module will extract the card reading data from the first response returned by the target passenger's associated tag, which usually includes key information such as the passenger's ID and card number. Then, the system will add the card reading data to the preset card reading success data queue for subsequent processing and analysis.

[0128] Step S27, setting the target passenger associated tag to a card reading success state through the UWB radio frequency module.

[0129] Among them, after completing the card reading operation and successfully obtaining the card reading data, the system will set the associated tag of the target passenger to the card reading success status through the UWB radio frequency module, indicating that the passenger has completed the card reading process.

[0130] This embodiment provides a travel interaction method. Before reading the card, it will first check whether the associated tag of the target passenger is in the authentication successful tag data queue. Only authenticated passengers can be identified and read by the system, effectively preventing unauthorized access and potential security risks.

[0131] Based on the first embodiment of the present application, in the fourth embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. On this basis, the rail transit system also includes a large reader and a gate, and step S20, performing corresponding interactive operations based on the area where the target passenger is located, also includes steps S28~S213:

[0132] Step S28, if the target passenger enters the preset card writing area, the UWB radio frequency module is used to check whether there are multiple target passenger associated tags in the card writing area in the card reading success state;

[0133] Among them, the target passenger enters the card writing area, and the UWB radio frequency module checks whether there are multiple tags with successful card reading in the card writing area. If so, it continues to check.

[0134] Step S29: if not, the card reading data in the card reading success data queue is obtained through the UWB radio frequency module and sent to the large reader;

[0135] If it does not exist, the card reading data in the queue is sent to the large reader.

[0136] Step S210, judging the card reading data by the large reader / writer, if the card reading data is valid, generating a card search success result, and sending the card search success result to the gate machine;

[0137] Among them, after receiving the card reading data, the large reader responds to the gate machine with the card search success result.

[0138] Step S211, constructing a transaction instruction through the gate machine and sending the transaction instruction to the large reader;

[0139] Among them, after the gate receives the successful card search result, it organizes and initiates the transaction instruction.

[0140] As an implementation method, a transaction instruction usually contains all the key information required to complete a transaction, including but not limited to the following (1) to (4):

[0141] (1) Passenger information: This is usually a unique identifier used to distinguish different passengers. In the application scenario of the UWB RF module, this identifier may come from the passenger's associated tag, such as card number, ID, etc.

[0142] (2) Transaction type: indicates the type of transaction, such as entry, exit, transfer, etc. Different types of transactions may involve different fare calculation rules and itinerary data matching logic.

[0143] (3) Timestamp: records the time when the transaction instruction is generated, used to ensure the timing and validity of the transaction.

[0144] (4) Other additional information: Depending on the specific application scenario, some additional information may also need to be included, such as discount information, discount codes, etc.

[0145] Step S212, performing itinerary data matching and fare calculation based on the transaction instruction through a large reader / writer to obtain the fare;

[0146] Among them, as an implementation method, when the large reader receives a transaction instruction from the gate machine, it will first parse the passenger information and transaction type in the instruction. Then, the large reader will access its stored itinerary database, which records each passenger's entry and exit records, transfer information, etc. Next, the large reader will search for the corresponding itinerary record in the itinerary database based on the passenger information and transaction type in the transaction instruction. This process may involve matching the time range, matching the station information, etc. If a matching itinerary record is found, the large reader will extract it for subsequent fare calculation.

[0147] After obtaining the matching trip data, the large reader will calculate according to the system's fare rules. These rules may be based on factors such as distance, time, station type (such as ordinary station, transfer station, etc.), passenger type (such as adults, students, elderly, etc.). During the fare calculation process, the large reader may also consider some preferential information or discount codes, which are usually provided in the additional information of the transaction instruction. Finally, the large reader will come up with a specific fare amount, which will be returned to the gate as part of the transaction result.

[0148] Step S213, based on the ticket price, complete the transaction operation through the gate, the large reader / writer, and the UWB radio frequency module.

[0149] Among them, based on the ticket price, transaction preparation, payment verification, tag reading and writing, status update, gate control, transaction records and settlement, etc. are required through gate machines, large readers and writers, and UWB radio frequency modules.

[0150] This embodiment provides a travel interaction method. Through the coordinated work of the gate, large reader / writer and UWB radio frequency module, passengers can quickly pass through the gate and reduce the waiting time in queues.

[0151] Based on the fourth embodiment of the present application, in the fifth embodiment of the present application, the same or similar contents as those in the fourth embodiment can be referred to the above description, and will not be repeated in the following. On this basis, step S213, based on the ticket price, completes the transaction operation through the gate, the large reader, and the UWB radio frequency module, and also includes steps S2131~S2133, S2135~S2137, S2139~S2140:

[0152] Step S2131, constructing a transaction initialization instruction based on the fare through the large reader / writer, and sending the transaction initialization instruction to the UWB radio frequency module;

[0153] The large reader / writer constructs a transaction initialization instruction based on the previously calculated fare information. This instruction contains basic transaction information, such as transaction type (consumption), passenger identification, fare amount, etc. After the construction is completed, the large reader / writer sends this instruction to the UWB radio module for further processing.

[0154] Step S2132, forwarding the transaction initialization instruction to the target passenger association tag through the UWB radio frequency module, and obtaining a second response returned by the target passenger association tag based on the transaction initialization instruction;

[0155] After receiving the transaction initialization instruction sent by the large reader, the UWB radio module forwards it to the target passenger's associated tag. After receiving the instruction, the associated tag will verify according to its own status (such as whether the balance is sufficient, whether it has been authorized, etc.), and return a second response to the UWB radio module.

[0156] Step S2133, sending the second response to the large reader / writer through the UWB radio frequency module;

[0157] After receiving the second response from the associated tag, the UWB radio module forwards it to the large reader, which will determine whether the transaction can continue based on the response.

[0158] Step S2135, constructing a consumption transaction instruction through the large reader and sending it to the UWB radio frequency module;

[0159] If the large reader determines that the transaction can continue according to the second response (for example, the balance of the associated tag is sufficient), a consumption transaction instruction is constructed. This instruction contains specific information about the consumption, such as the consumption amount, passenger identification, etc. After the construction is completed, the large reader sends this instruction to the UWB radio module.

[0160] Step S2136, forwarding the consumption transaction instruction to the target passenger associated tag through the UWB radio frequency module, and obtaining a third response returned by the target passenger associated tag based on the consumption transaction instruction;

[0161] After receiving the transaction instruction sent by the large reader, the UWB RF module forwards it to the associated tag of the target passenger. After receiving the instruction, the associated tag will perform the consumption operation (such as deducting the corresponding amount) and return a third response to the UWB RF module.

[0162] Step S2137, sending the third response to the large reader / writer through the UWB radio frequency module;

[0163] After receiving the third response from the associated tag, the UWB radio module forwards it to the large reader, which will confirm whether the transaction is successfully completed based on this response.

[0164] Step S2139, sending a transaction success response to the gate machine through the large reader;

[0165] If the large reader determines that the transaction has been successfully completed according to the third response (for example, the associated tag has successfully deducted the corresponding amount), it sends a transaction success response to the gate. This response indicates that the transaction has been successful and the gate can perform the corresponding operation (such as opening the gate).

[0166] Step S2140, receiving the transaction success response through the gate and completing the transaction.

[0167] After receiving the successful transaction response from the large reader, the gate machine confirms that the transaction has been successfully completed. At this time, the gate machine can perform corresponding operations to complete the transaction process, such as opening the gate to allow passengers to pass.

[0168] This embodiment provides a travel interaction method. Through the coordinated work of the gate, large reader and UWB radio module, passengers can quickly pass through the gate, reducing the waiting time in line. In addition, this application simplifies the number of interactions with the large reader during the payment process, improves transaction speed, and reduces failure rate. This application adopts a multi-module distributed processing solution with higher execution efficiency.

[0169] Based on the fifth embodiment of the present application, in the sixth embodiment of the present application, the same or similar contents as those in the fifth embodiment can be referred to the above description, and will not be described in detail later. On this basis, the step S2135, before constructing the consumption transaction instruction through the large reader and sending it to the UWB radio frequency module, also includes step S2134:

[0170] Step S2134, performing a first message authentication code verification on the response data in the second response through the large reader;

[0171] If the first message authentication code is successfully verified, step S2135 is executed: a consumption transaction instruction is constructed through the large reader and sent to the UWB radio frequency module.

[0172] In order to ensure the integrity and authenticity of the response data, the large reader will perform a message authentication code (MAC) check on the response data in the second response.

[0173] Message authentication code is a technology used to verify the integrity and authenticity of information. It generates a fixed-length authentication code through a specific algorithm based on a key and a message (here, the response data). The receiver (here, the large reader) recalculates the authentication code for the received message using the same key and algorithm, and compares it with the authentication code provided by the sender (here, the associated tag, forwarded through the UWB radio module). If the two match, it means that the message has not been tampered with during transmission and is indeed from a legitimate sender.

[0174] Therefore, in step S2134, the large reader / writer uses a predefined key and algorithm to perform a first message authentication code check on the response data in the second response to ensure the integrity and authenticity of the data.

[0175] The step S2139 includes step S2138 before sending a successful transaction response to the gate machine through the large reader / writer:

[0176] Step S2138, performing a second message authentication code verification on the response data in the third response through the large reader;

[0177] If the second message authentication code verification is successful, step S2139 is executed: a transaction success response is sent to the gate machine through the large reader / writer.

[0178] Similar to step S2134, step S2138 involves the large reader verifying the message authentication code of the third response from the target passenger's associated tag forwarded by the UWB radio module. This response contains the processing result of the associated tag on the consumption transaction instruction (such as whether the consumption is successful, the remaining amount, etc.).

[0179] In step S2138, the large reader uses the same key (or another predefined key, depending on the system design) and algorithm as in step S2134 to perform a second message authentication code check on the response data in the third response. This verification process is intended to ensure the integrity and authenticity of the third response data, thereby confirming whether the consumption transaction is successfully completed and that the response is indeed from the legitimate sender (i.e., the associated tag of the target passenger).

[0180] This embodiment provides a travel interaction method. Through two message authentication code verification steps, the system can increase the security and reliability of the transaction process and prevent data from being tampered with or forged during transmission.

[0181] Based on the sixth embodiment of the present application, in the seventh embodiment of the present application, the same or similar contents as those in the sixth embodiment can be referred to the above description, and will not be described in detail later. On this basis, step S10, the area where the target passenger is located is detected by the UWB radio frequency module, and the area where the target passenger is located includes a preset authentication area, a card reading area or a card writing area, including steps S11 to S13:

[0182] Step S11, scanning and receiving the UWB signal emitted by the target passenger associated tag carried by the target passenger through the UWB radio frequency module, and recording the intensity and round-trip time of the UWB signal;

[0183] Among them, the UWB radio frequency module deployed in specific areas (such as stations, airports, access control systems, etc.) actively scans the UWB (ultra-wideband) signals in the surrounding environment. When the target passenger carries a device equipped with a UWB associated tag (such as a smart bracelet, card, mobile phone, etc.) and enters the area, its associated tag will emit a UWB signal. After receiving these signals, the UWB radio frequency module will record the signal strength (usually expressed in decibel milliwatts dBm, reflecting the power of the signal) and the round-trip time of the signal (that is, the time difference from the UWB radio frequency module transmitting the inquiry signal to receiving the response signal from the associated tag).

[0184] Step S12, calculating the distance of the UWB signal based on the round-trip time;

[0185] The UWB RF module uses the recorded round-trip time and the known speed of electromagnetic wave propagation (about the speed of light in air) to calculate the distance the UWB signal travels from the UWB RF module to the target passenger's associated tag and back through simple mathematical calculations (distance = speed × half of the time, because the calculation is a one-way distance).

[0186] Step S13, judging the area where the target passenger is located as the authentication area, the card reading area or the card writing area based on the strength and distance of the UWB signal.

[0187] Among them, since this application predefines different areas (such as authentication area, card reading area, card writing area, etc.), each area corresponds to different business logic and security requirements. The UWB radio frequency module determines the area where the target passenger is currently located based on the strength of the received UWB signal and the calculated distance information, combined with the preset area division rules (such as distance threshold, signal strength threshold, etc.).

[0188] This embodiment provides a travel interaction method. This application uses UWB technology to achieve high-precision positioning and area judgment of target passengers, providing reliable data support for subsequent authentication, card reading, card writing and other operations.

[0189] For example, to help understand the implementation process of the travel interaction method of the above embodiment, please refer to Figure 4 , Figure 4 This is a schematic diagram of the UWB payment gate processing flow for this application.

[0190] Among them, this plan divides the card swiping behavior of passengers entering the gate into three stages.

[0191] 1. The first stage is the UWB certification stage.

[0192] 1.1 When a passenger arrives near the gate, since the passenger holds a tag product with UWB function, the passenger's positioning information can be updated through the UWB radio frequency module to determine whether the distance between the passenger and the UWB radio frequency module is less than the authentication area. If the distance between the passenger and the UWB radio frequency module is greater than or equal to the authentication area, no processing will be performed.

[0193] 1.2. If the distance between the passenger and the UWB RF module is less than the authentication area, the UWB RF module detects that the passenger has entered the authentication area and determines whether the authentication is successful.

[0194] 1.3. If the authentication fails, the FIRA authentication process is started, a secure transmission channel is established, and it is determined whether the startup is successful. If the startup is successful, the tag status is set to the authentication success status, and the tag MAC address is added to the authentication success data queue; if the startup fails, the tag status is set to the reset status and the positioning information is updated again.

[0195] 1.4. If the authentication is successful, determine whether the distance between the passenger and the UWB RF module is less than the card reading area. If the distance between the passenger and the UWB RF module is greater than or equal to the card reading area, re-update the positioning information. If the distance between the passenger and the UWB RF module is less than the card reading area, enter the UWB card reading stage to determine whether the card reading is successful. If the card reading fails, execute 2.1. If the card reading is successful, determine whether the distance between the passenger and the UWB RF module is less than the card writing area. If the distance between the passenger and the UWB RF module is greater than or equal to the card writing area, update the positioning information. If the distance between the passenger and the UWB RF module is less than the card writing area,

[0196] 2. The second stage is the UWB card reading stage.

[0197] 2.1. The UWB radio frequency module organizes a comprehensive card reading data instruction package, which includes an application selection instruction, a read file 1 instruction, a read file n instruction, and a read wallet instruction, and sends the comprehensive card reading data instruction package to the UWB tag.

[0198] 2.2 Obtain the data packet response returned by the UWB tag, and determine whether obtaining the data packet response returned by the UWB tag is successful.

[0199] 2.3. If the data response returned by the UWB tag fails, update the positioning information.

[0200] 2.4. If the data packet response returned by the UWB tag is obtained successfully, the card reading data is added to the card reading success data queue through the UWB radio frequency module, and the card reading success status flag is set to determine whether there are multiple tags in the card writing area.

[0201] 3. The third stage is the UWB card writing stage.

[0202] 3.1. When the passenger enters the card writing area, the UWB RF module checks whether there are multiple tags with successful card reading in the card writing area. If so, it continues to check.

[0203] 3.2. If it does not exist, take the card reading data from the queue and send it to the large reader.

[0204] 3.3. When the large reader receives the card reading data, it will parse and store the card reading data and respond to the gate machine with the result of successful card search.

[0205] 3.4. After receiving the successful card search result, the gate organizes and initiates the transaction data instruction.

[0206] 3.5. After receiving the transaction instruction, the large reader matches the travel data and calculates the fare.

[0207] 3.6. After the calculation is completed, the transaction initialization instruction will be organized according to the fare and sent to the UWB radio module.

[0208] 3.7. The UWB radio frequency module forwards the transaction initialization instruction packet to the UWB tag and obtains the correct response. The UWB radio frequency module sends the correct response to the large reader.

[0209] 3.8. The large reader performs MAC1 calculation and verification on the response data.

[0210] 3.9. After successful verification, the consumption transaction instruction is organized and sent to the UWB radio frequency module. After receiving it, the UWB radio frequency module forwards the UWB tag and obtains the correct response.

[0211] 3.10. The UWB radio module sends the correct response to the large reader.

[0212] 3.11. After the large reader receives the response, it performs MAC2 verification.

[0213] 3.12. After the large reader / writer successfully verifies, it sends a successful transaction response to the gate machine.

[0214] 3.13. The gate completes the entire transaction after receiving the response.

[0215] Therefore, this application decentralizes the entire payment process, distributes processing, splits payment tasks, and processes multiple modules in a collaborative manner, which can improve the utilization rate of each module and speed up the payment processing process. In addition, this application divides a single payment process into an authentication stage, a card reading stage, and a card writing stage, and processes the payment process by stage, which can improve the gate's ability to handle multiple tags passing through the gate continuously.
