1 Introduction
Since the birth of NFC technology, China Mobile E-Commerce Innovation Product Base has adopted the UnionPay 13.56MHz mobile payment standard in 2011, which indicates that operators and banks will jointly promote the standardization of mobile payment technology. In December 2013, China Mobile Relying on NFC technology, the mobile phone wallet business was named "and package". In 2015, China's financial IC card issuance exceeded 1 billion, and the People's Bank of China will fully apply financial IC cards, which in turn gave NFC payment a shot in the arm. Due to the high compatibility between the financial IC card and the NFC in the acceptance environment, the POS machine brought by the popularization of the financial IC card has been completely updated, which has paved the way for the application of NFC for mobile phones and other devices.
2. NFC technology application scenario
NFC (Near Field Communication Technology) is an evolution of contactless radio frequency identification (RFID) and interoperability technology that combines inductive readers, inductive cards and point-to-point functions on a single chip. Identification and data exchange with compatible devices, operating at 13.56 MHz. The applications that NFC can bring to us are very rich, and in general they can be divided into three categories:
The first type is the application of electronic cards. It can convert cards of physical cards such as bank cards, bus cards and membership cards into electronic cards, and use mobile phones as smart cards. With such integrated functions of electronic cards, no matter whether it is by bus or shopping, Still playing the attendance, the members only need to easily brush the phone to get it.
The second type is the application of reading information, that is, using NFC as a card reader, and reading the NFC tag to obtain information, which can be used for logistics management, product traceability, conference sign-in, and the like. You may say that these features are also available in the QR code. Where is the feature of NFC? Compared with the QR code, NFC is more convenient to use. The use of the QR code may be perceived. When the QR code is used. Need very accurate comparison labels, and need to wait for a long time, but with NFC, you only need to touch within a certain distance range, do not need such accurate content, and the speed of obtaining information is also better than the QR code. It is several times faster. At the entrance of the venue today, the NFC sign-in was placed and a lottery session was set up. Participants only need to take the signs you have now to report, and you can also see the information of the participants by signing in, and you can also participate in the lucky draw.
The third category is interactive applications that allow peer-to-peer information transfer and file sharing. As long as the NFC function in your hand is turned on and the two mobile phones touch it, you can easily complete the business card exchange, so that there will be no embarrassment that the business card is not brought.
The application of NFC will make our life become a machine and travel without worry. With the development of public transportation in various provinces and cities, the use of public transportation cards has provided the citizens with fast and convenient services, but recharging has become a difficult point in the operation of the card. There are many recharge points, high operating costs, and fewer recharge points. The public is not convenient. This paper is based on the mobile public card card issued by mobile, which can carry the application of public transportation and other industries, and can use the mobile and package accounts to complete the recharge of the bus card in real time. The user can also realize the mobile phone credit card ride, which not only improves the information level of public transportation, but also solves the problem of air traffic. It is difficult to recharge, reduce payment outlets, reduce labor costs, reduce counterfeit banknotes, and solve queues and other service problems.
3, and package NFC bus overall architecture
NFC cards belong to the category of CPU cards. NFC can not only realize the ordinary bus card function, but also solve the problem of opening and recharging ordinary bus cards. The bus card is to carry the bus application through the operator and the package card in the air. It can also use the air card to carry the bus application to replace the original bus card card method by brushing the mobile phone, so that one machine can be used to brush the bus.
According to the different stages of the operator's business development, the bus application can be carried by the mobile dual-interface card, NFC and other mode card forms. Due to the limitation of the popularity of the NFC terminal of the user, the mobile bus application solution needs to meet the requirements of different card forms.
For the operator's bus application, it is necessary to construct an operator bus service processing platform to meet the business processing functions of the operator's bus cooperation. For the carrier bus application under the NFC mode, it is also necessary to develop the operator and the bus application client. Complete related business.
(1) Mobile platform:
Mobile platform multi-application download management platform and key management system centralized management card application download, air card opening, air recharge, query, consumption record, delete and other statistical analysis of the transaction, provide data basis for card application operations, support provincial card application Access and management.
(2) Bus platform:
The bus system is responsible for user operation authentication, application personalization generation, generation of recharge instructions, and auxiliary security domain information management.
(3) Card dealer card issuing system:
After the card is shipped from the factory, the card protects the bus protection key in the card. The protection key is generated according to the SEID of the card according to the key code list provided by the bus or mobile, thereby ensuring one card and one secret. At the same time, this protection key is only used by bus applications. This protection key provides security protection for the writing of the application key of the card, the transaction key of the card, and the like.
At the time of card issuance, the encryption provider provides each card issuer with a card reader and a key mother card for card issuance. Since the bus NFC application is issued in the air, the previous card issuance process cannot meet the needs, and the encryption provider needs to provide the key to be imported into the encryption machine. The bus system accesses through the API.
(4) Mobile phone NFC terminal / NFC card
The NFC card for the Jiayuguan bus card has been pre-fabricated in accordance with the standard specifications, and supports the APP application and data interaction functions.
(5) NFC card side
The bus card side auxiliary security zone (SSD) is responsible for storing the bus card communication key and the DAP verification key (the DAP verification key is optional). When the card application deals with the outside world, the secure communication function of the SSD can be used to protect the interactive data security.
The card application realizes the bus card user to pay for the bus by the radio frequency interface.
(6) Air account opening
Through the NFC bus application client, the provincial mobile bus service processing platform, and the bus platform, the NFC bus client writes the card request, operates, generates the bus application account opening information, and displays the application management function through the mobile phone and the package client application, and the client plug-in. Cooperate with the application personalization and other operations.
(7) NFC air recharge
NFC air recharge means that the user can use the mobile 4G network to recharge the bank account with the package payment account or the third party payment channel on the NFC mobile phone client. For the service platform and the card, a unified report can be used. The text structure implements the interaction. The NFC bus service processing module completes the business processing with the application platform according to the specific application requirements, and docks with the payment platform to complete the work of deduction and correction. The client provides user interaction interfaces such as user authentication, balance inquiry, transaction record query, etc., and interacts with the card application bus system through the mobile phone and the package client message transparent transmission interface to complete the corresponding functions.
4, summary
With the deepening application of "Internet +" public transportation NFC payment technology, especially mobile phone-based NFC payment, NFC has an irreplaceable advantage in terms of payment convenience and security. NFC technology is practically applied in public transportation as an entry point. It is believed that NFC technology will gradually upgrade to urban card or citizen card under public transportation application, and finally realize one card multi-use and convenient payment. First, the application scene and technology carrier that open the city card and the offline POS have been formed. Second, the NFC payment based on mobile phones is large, and the business areas involved are constantly expanding into the living, food, housing and transportation sectors. Third, the mobile payment population is growing at a very high rate, no longer relying on cash or The card is a payment carrier; Fourth, the financial transaction method based on NFC payment technology has received global attention, or will become a new financial payment carrier; Fifth, China Mobile Payment is growing at an alarming rate, and consumers are shopping for transactions. The profound changes have taken place. Sixth, NFC payment technology based on smart phones is currently becoming the focus of the market. Its application fields and scope are further expanding.
