Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a rail transit multimodal reading and writing system. Background Art

[0002] In the early days, rail transit ticketing mainly relied on paper tickets. This type of ticket requires manual ticket sales and ticket checking. Passengers need to queue up at the ticket window to buy tickets between specific stations, and the staff will manually check the tickets when entering and exiting the station. This method is not only inefficient, but also prone to human errors, such as fake tickets, wrong tickets, etc. With the development of technology, magnetic card tickets have emerged, which store information through magnetic strips to achieve automatic ticket checking, but magnetic strips are easily interfered by magnetic fields, have limited information storage capacity, and may lose or damage data after long-term use.

[0003] With the emergence of new Internet-based transportation tools, such as mobile NFC transportation cards, rail transit QR codes, and rail transit reader-writer systems, they need to be constantly updated. At the same time, with the acceleration of globalization, exchanges between countries around the world in the fields of economy, culture, education, and tourism are becoming increasingly frequent. As the center of economy and culture, cities have attracted a large number of foreigners to work, study, travel, and live. This large-scale population flow has made urban public transportation, especially urban rail transit, an important way for foreign passengers to travel on a daily basis. According to relevant statistics, in many international metropolises, the annual passenger flow of foreign passengers has shown an upward trend year by year, which has put forward higher requirements on the service capacity and quality of urban rail transit.

[0004] More importantly, public safety issues are receiving increasing attention. In a crowded public transportation environment such as rail transit, real-name ticket purchase and ride can help improve safety. By accurately recording the identity of passengers, personal information can be quickly traced in the event of a security incident, assisting in investigating and responding to potential terrorist attacks, public security incidents, etc. For example, during some large-scale events or special periods, strict identity verification of people riding rail transit can effectively prevent criminals from entering the rail transit system.

[0005] Therefore, designing a multimodal reading and writing system for rail transit is an urgent problem to be solved. Summary of the invention

[0006] In order to solve the technical problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a rail transit multimodal reading and writing system, which can realize multi-media identification and interaction and has a high-performance reader-writer ticket processing system, as well as realize real-name ticket purchase for domestic and foreign users.

Obviously, the drawings described below are only some embodiments of the present invention, and for ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0032] Figure 1 The figure schematically shows the composition of the rail transit multimodal reading and writing system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0033] The description of the embodiments of this specification should be combined with the corresponding drawings, which should be considered as part of the complete specification. In the drawings, the shape or thickness of the embodiments may be enlarged and indicated for simplification or convenience. Furthermore, the parts of each structure in the drawings will be described separately. It is worth noting that the elements not shown in the drawings or not described in words are in a form known to ordinary technicians in the relevant technical field.

[0034] The description of the embodiments herein and any reference to directions and orientations are only for the convenience of description and are not to be construed as any limitation on the scope of protection of the present invention. The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination, and the present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0035] like Figure 1 As shown, the present invention proposes a rail transit multimodal reading and writing system, including a processor module and an identification module, an ID card processing module, an ODA authentication module, and a SAM module connected to the processor module.

[0036] The present invention can be applied to scenes such as gate terminals or self-service ticket purchasing terminals of rail transit. By configuring a processor module, an identification module, an ID card processing module, an ODA authentication module, and a SAM module in the system, the integration of multiple technologies such as RFID, NFC, and QR code scanning can be realized. Combined with the improvement of the Internet application platform and the post-payment payment system, the present invention can meet the diversified payment needs of modern urban rail transit systems, improve the efficiency of riding, significantly enhance the user experience, and has a high market application value and promotion prospects. On the basis of solving many problems in the use of traditional transportation cards, it further promotes the business upgrade of public transportation and drives the further development of the transportation card field.

[0037] Based on the various modules of the present invention, various card usage problems of traditional transportation cards can be optimized, and the reading and writing of NFC, QR code, digital currency, super SIM card, UnionPay card, foreign card, ID card and other ticket media can be realized in the same system, and many offline processing processes can be adjusted to online, which effectively solves the waste of human resources and system resources in rail transit travel scenarios and improves the operational efficiency of rail transit.

[0038] The multifunctional reader / writer system that can handle a variety of ticket media has become increasingly sophisticated, enabling efficient boarding of various media. While promoting various new types of gate-passing media, it also ensures the user experience to the greatest extent possible.

[0039] The identification module includes a radio frequency submodule, a bank card identification submodule, an ID card submodule, and a QR code submodule;

[0040] The radio frequency submodule is used to identify and read RFID cards and NFC cards, and complete the ticket card data interaction through the processor module, write cards, consume, and deposit RFID cards and NFC cards, and generate transactions and upload them to the terminal device.

[0041] The radio frequency submodule is also used to identify digital currency and super SIM cards. When digital currency or super SIM cards are identified, the processor module uses the national secret algorithm to verify the data, parses the valid data read, generates a transaction and transmits it to the terminal device, which then transmits the corresponding data to the Internet background for transaction matching and deduction.

[0042] In some embodiments of the present invention, the radio frequency submodule is also used to read the user's ID card when purchasing tickets, and the ID card processing module completes encryption and decryption to complete real-name ticket purchase.

[0043] The radio frequency module of the reader in the prior art can only process TYPE-A cards, and the ID card is a TYPE-B card. Therefore, it is necessary to modify the radio frequency module of the reader and writer, and add a new ID card processing module hardware. The ID card information read by the radio frequency sub-module of this application sends the read ID card original data to the ID card processing module. The ID card processing module calls the SAM card module to process the ID card original data, obtains the ID card information through verification and decryption, and returns the ID card information to the processor module to complete the real-name ticket purchase.

[0044] The present invention utilizes a radio frequency submodule and an ID card processing module to read ID card information and complete real-name ticket purchase.

[0045] For the RF submodule and ID card processing module to read the ID card information, just put the ID card close to the corresponding device to quickly obtain the personal information in the ID card. This automated information reading method greatly shortens the time of manual information entry, avoids possible errors caused by manual input, and makes the ticket purchase process smoother and more efficient, especially in ticket sales scenarios with large passenger flow, which can significantly reduce the waiting time of users.

[0046] The information reading system is directly connected to the real-name ticket purchasing system. After obtaining the ID card information, it can be verified immediately. Once the verification is passed, the ticket purchase can be completed quickly. Users do not need to wait in line for manual ID inspection and then go to another window to buy tickets as in the past. The whole process is fast and convenient, greatly improving the efficiency of ticket purchase.

[0047] When manually entering ID card information, data entry errors may occur due to visual fatigue, carelessness, etc., such as typos in names, confusion of ID card numbers, etc. Automatic reading methods such as ID card recognition submodules and radio frequency technology can obtain information with extremely high accuracy, ensuring the accuracy of user personal information in ticket purchase and other links, and avoiding subsequent troubles caused by information errors.

[0048] The system reads ID card information according to the set procedures and standard formats, ensuring the standardization and consistency of all user information. The user's ID card information can be stored and processed in a unified format, which is convenient for the management and query of the ticketing system and also provides a high-quality data foundation for subsequent data analysis and other work.

[0049] In some embodiments of the present invention, the QR code submodule is used to process rail transit related QR codes.

[0050] After identifying the QR code related to rail transit, the QR code submodule reads the data information of the QR code and sends it to the processor module. According to the characteristics of the rail transit scenario, the specific data in the QR code is decrypted and signed using the national secret algorithm. The public key of the authentication center is saved in the reader parameter file. According to different indexes and other information, the corresponding public key is found in the parameter file. This method improves the security of the public key. Through three-layer data verification, the national secret algorithm is applied to rail transit to ensure the security of data.

[0051] The bank card identification submodule is used to identify the bank card and complete the deduction transaction through the ODA authentication module and the processor module.

[0052] In some embodiments of the present invention, the bank cards include UnionPay cards and non-UnionPay cards, and the non-UnionPay cards include at least Visa cards, Mastercard cards, American Express cards, and JCB cards, realizing functions such as direct card swiping of foreign bank cards such as VISA and MasterCard to pass through gates, purchase tickets, make up tickets, and refund, eliminating the user's additional steps of opening, registering, or binding applications, and having the characteristics of convenience and efficiency.

[0053] In some embodiments of the present invention, after the bank card identification submodule identifies a domestic UnionPay card, it reads the card file content, parses and verifies it according to the domestic UnionPay UICS standard, and performs ODA authentication on the card, parses out the key card data, generates a transaction and transmits it to the terminal device. The terminal device then transmits this data to the subway ticketing backend, and then to the acquiring institution backend for transaction matching, deduction and other operations.

[0054] In some embodiments of the present invention, after identifying a foreign bank card, the bank card identification submodule reads the card file content, parses and verifies it according to the EMV standard of the international card organization, and performs ODA certification on the card, parses out the key card data, generates a transaction and transmits it to the terminal device, and the terminal device then transmits this data to the subway ticketing backend, and then to the acquiring institution backend, and finally reaches the foreign card organization backend through the domestic agent bank of the foreign card organization for online card verification, pre-authorization and deduction operations.

[0055] By simplifying the entry and exit processes to provide a seamless and fast user experience while ensuring the security of funds, it can also reduce the number of operation steps and waiting time for users when entering and exiting the station, improve passage efficiency, reduce communication costs, and use the back-end system to handle complex verification and settlement work.

[0056] Users can quickly enter the station by simply tapping their card on the card reader, without having to wait for the pre-authorization result. The entire process is transparent to the user, who does not need to perform additional operations or wait. Even if the pre-authorization fails or one side of the transaction is missing, it will not affect the user's normal entry and exit.

[0057] In some embodiments of the present invention, it further comprises:

[0058] Parameter module, parameterization is to adapt to the system operation and operation needs, meet the business change requirements, and control the pre-made data of the specified business implementation. Parameter data is divided into ACC parameters, card parameters, QR code and bank card public key parameters according to different data sources. The parameters define the processing specifications, operation requirements and public keys required for processing of various types of tickets, QR codes, bank cards, etc. processed by the reader. The parameterization of the reader software realizes the parameterization of ticketing rules. According to the operation needs of the operating enterprise, different functions and ticketing rules can be realized by setting different parameters;

[0059] Data security processing: When the RF submodule identifies a one-ticket card or one-card card and needs to read or write card data, in order to prevent unauthorized reader / writer devices from illegally tampering with the card or swiping the card with an illegal reader / writer, the system will extract a random number from the card before any card reading and writing operation. Subsequently, the random number will be encrypted using the DES algorithm by calling the SAM card module. The card will use the same key to decrypt the encrypted data. Only when the data is verified to be correct will the subsequent card reading and writing business processes continue.

[0060] For Internet product tickets such as QR codes, key data in the data transmitted between the tickets and readers is encrypted using the national secret algorithm, and the key is stored in the parameters of the reader in the rail transit station, effectively ensuring that key information will not be intercepted or leaked by a third party.

[0061] For personal documents such as ID cards, the data transmitted by the ID card and the reader are encrypted data. After the business process is completed, all data of this interaction will be cleared, and no identity information will be retained locally, thereby eliminating the risk of privacy information leakage.

[0062] The serial numbers of the above-mentioned steps involved in the method of the present invention do not mean the order of execution of the method. The execution order of each step should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the implementation mode of the present invention.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
