The Research On Mobile Payment Based On 2.4G RF Technology

Mobile payment business means that based on the mobile communication network and Internet technology, the use of mobile phones, through the short message, STK, voice, WAP ways, through the mobile payment account for consumption, prepaid phone, transfer, inquires the etc, and electronic business operation related business management business. Through the mobile payment business provides ability to pay, the user can for objective commodity, digital goods, services and the purchase of the telecom data value-added business pay. At present, the realization of the mobile phone mobile payment way mainly through SMS, GPRS, WAP, STK, remote control way to complete. This way there are obvious deficiency: the one is the way to realize the high cost of complex. Two is trading process trival, trade time is too long, low approval users; Three is difficult to guarantee security trading.In this paper the research is based on RFID technology mobile payment system, puts forward the general framework for the mobile payment system design, from RF_SIM clip next system design, card reader subsystem design, collimator subsystem design, RF interface protocols four are studied. Among them, to provide RF_SIM system design and RF interface protocols do with emphasis. In the mobile payment system design, safety is very important. In this paper, the safety of payment system are analyzed in detail, including RF_SIM card safety system, safety backup and restore data mechanism. Developing suitable small mobile payment of mixed used encryption algorithm, the significance of application for system is very important. This paper hold the mobile payment system special application environment, the design and realized based on 3 DES, improve the blending of RSA algorithms encryption algorithm, greatly improving the data encryption speed. In deposits, many important link of trade can be used by the mixed algorithm encryption. This paper introduces the design of mobile payment business process, show the mobile payment system realization structure and the actual business operation interface.The system can achieve more operators, many areas, many fields use, give full play to the mobile phone "anywhere, at any time, with the characteristics of,", reflect the convenient, quick and fashionable way of life, has realized the small range of commercial. Finally, the development of mobile payment, evolution put forward some forward-looking point of view.RF_SIM card is used for mobile phone user identification card. RF_SIM card innovation in 2.4 G wireless radio frequency (RF) module set to SIM CARDS, so as to completely change the traditional SIM card can only and mobile phone communication shortcomings, make RF_SIM may at any time and the surrounding equipment on interactive, and would not affect the SIM card original function. RF_SIM can be widely used in electronic payment van, the identification and information transfer and other various application field, thus promote telecommunications and bank, transportation and other areas of further integration. In addition, this paper puts forward three DES based on RSA algorithms, improve the mix of encryption algorithm, this algorithm can satisfy the financial system of the high security and encryption and decryption process the quickness of management flexibility and so on various aspects of the requirements.This paper introduces the design of mobile phone pay business process basic can meet the demand of the market, but the system still exist in the following several aspects of the problem. One is the account limit. No support account and bank CARDS binding. Two is the limit cost way. Currently only support business hall, this way of prepaid phone for customer brought a lot not convenient place.
