Design And Implementation Of Film Encryption Card

With the development of information society,the mobile phone has become the way people work and live without the necessities.In recent years,bank s and other financial agencies to strengthen the "mobile financial services," the development plan,the core technology is the introduction of the mobile phone users of their services,that allow the integration of financial cards with existing SIM card ph one system,and thus a better launch all kinds of mobile financial services.However,due to various constraints,it is difficult to find in such a way.In order to support remote payment,easy to use,this paper SIM cards for mobile phones made development of the "film encryption card" to study,design and implementation of a SIM-based encryption card,and a detailed study of the associated circuitry and hardware and software modules implementation.Currently on the encryption card used by many types of t he financial sector,it can be divided into key type,voice type.These encryption cards mostly used in personal computers,in the field of mobile payments,currently all domestic products are external,encrypted mobile phones are on the phone motherboard add-in-one encryption module,resulting in encrypted phones are professional phone models,can not meet the user not to replace the phone number you can not replace the requirements of encrypted payment.Similar foreign encryption products,but on the domestic smart phones,and so on domestic 3G standard is not well supported.In encryption card design,this paper proposes a paste innovative implementation methods and products to form a dual smart card system thin film composite smart card SIM card.The traditional mobile phone motherboard add-in-one encryption module to encrypt mobile phone without requiring the user to replace the existing mobile phone SIM cards and mobile terminals case,attached to the user's mobile phone SIM card "films encryption card" preset application via SMS channel,combined with the phone's display and keypad,electronic banking can be jointly completed application.Banks can no user changing the card,under the premise for mobile phone users launched more financial applications a nd services,mobile phone users quickly complete remote payment,transfer payment and other services,so that the use of a variety of means and channels develop existing mobile phone users as their value-added service users,to bring a new market space for development financial institutions.
