Foreword
RFID is the abbreviation of RadioFrequencyIdentification, which is radio frequency identification, which is a non-contact automatic identification technology. It automatically recognizes the target object and acquires relevant data through the RF signal, and the identification work can work in various harsh environments without manual intervention. RFID technology can recognize high-speed moving objects and recognize multiple labels at the same time, which is quick and easy to operate. For example, when the RFID tag enters the magnetic field, it receives the RF signal from the reader, and sends the product information (Passive Tag, Passive Tag or Passive Tag) stored in the chip by the energy obtained by the induced current, or actively sends a certain one. The frequency signal (Active Tag, active tag or active tag); the reader reads the information and decodes it, and sends it to the central information system for data processing.
The mobile phone card (RFID-SIM card) embeds the radio frequency module into the SIM card of the mobile phone, so that the SIM card has the function of the radio frequency identification card at the same time, so that the mobile phone can perform inductive data exchange with the card reading device. In this way, the user does not have to change the mobile phone, in addition to the original SIM card communication function, it can also implement various payment operations and identity authentication.
Under the strong promotion of the three major operators in China, the mobile phone card has shown a rapid development since 2009. For operators, after implementing the mobile phone card, they can attract non-mobile phone users or mobile phone users of other operators, and increase the user's viscosity for existing users. At the same time, as a means of on-site payment, operators can achieve “backgroundâ€. "Financial" - "remote online payment" - "mobile phone card offline payment" integration strategy. For the unit, due to the investment of the operator, the card of the campus, enterprises and institutions can be realized at a very low cost. For the user, after the mobile phone card is realized, the user can enjoy the operation, the access control, the attendance, the parking lot access and the like through the operation of the mobile phone, and enjoy great convenience.
Campus Card Application Overview
At present, there are many sets of systems closely related to card, card, ticket and cash use in the university area, such as: supermarket consumption system, library management system, dormitory access control system, computer room management system, school bus system, hot water supply system, etc. Because each system has a corresponding independent management system, it brings certain inconvenience to the unified management, financial management and student use of the school. By building a mobile phone card platform based on 2.4GHZRF-USIM card technology, all the systems in the school that are closely related to cards, certificates, tickets and cash use will be integrated to replace the original card with a mobile phone. Certificates, tickets, and cash facilitate the teaching, research, study, life, and management of the school's teachers and students. While facilitating the majority of teachers and students, improve the management level and service level of the school, reduce the investment of the school, teachers and students in cards, certificates and tickets, and also achieve financial in the process of replacing the original card, card, ticket and cash. The purpose of the management.
Introduction to mobile payment:
Mobile payment refers to the RFID mobile phone that the user uses the built-in on-site payment account. In the merchant that installs the POS device that supports the mobile payment account, the service type of the payment transaction is completed by the proximity communication method (RFID).
Mobile payment features:
â—† New technology: adopt advanced technology RFID communication method and financial IC card application
â—† High security: use financial-grade encryption
â—† Easy to use: It has the characteristics of portable, versatile and easy-to-use; integrate traditional cards such as access cards, consumption cards, time cards, and discount cards with mobile phones.
According to the application division of mobile payment, it is divided into inter-city consumption and fixed-use areas (such as campus and enterprise); the latter belongs to the so-called mobile phone card.
Classification of mobile payment technology:
The mobile phone payment promotion program including the whole terminal solution and the cooperation between the mobile phone and the SIM card has not been introduced into the country due to the cooperation of the mobile phone; and the scheme similar to the "patch card" is only physically attaching the IC card and the mobile phone. Together, it can't be bundled with the mobile phone and has no scalability, so it is not conducive to operator promotion. More mature, successfully applied technology is the domestic independent SIMpass solution and RF-SIM solution, as shown below:
Construction experience sharing
The mobile phone card system is a huge system. The success or failure of its construction involves all aspects. In addition to the selection of various related devices, it is mainly reflected in whether the mobile phone card system has a good application integration design. And the ability to integrate existing systems and the ability to integrate systems deployed in the future according to school needs. If the mobile phone card system does not solve this problem well, then the mobile phone card platform can only be one that is not open, and there is no technological advancement that can't satisfy the school's mobile phone card system. For the consideration of the advanced nature of the mobile phone card system, it is necessary to examine whether it can meet the construction needs of the campus business itself, but also whether it has sufficient scalability and whether it can be smoothly upgraded in the future according to the needs of the school's own information construction. A digital campus solution that guarantees continuity of use while ensuring long-term effectiveness of the school's investments.
Conclusion
At present, Card's smart card system has been perfected, and serves the major enterprises and institutions to jointly promote the development of RFID radio technology in mobile payment and mobile e-commerce. We believe that in the near future, RFID radio frequency technology will become the most popular mobile phone application technology and will be greatly promoted by various telecom operators, and it is of great significance to improve customer convenience services.
