Abstract

The invention discloses a dual protocol supporting contact-less communication smart card. The contact-less communication smart card comprises a SIM (Subscriber Identity Module) card base with a built-in antenna coil, a dual-interface module supporting a 14443 protocol and a 7816 protocol, and a SWP (Single Wire Protocol) security module supporting a SWP and the 7861 protocol. The built-in antenna coil is connected with the dual-interface module and transmits contact-less information; the dual-interface module is connected with a mobile phone and transmits instruction information in line with the 7891 protocol; the dual-interface module is connected with the SWP security module and transmits external contact-less instruction information according to the 7816 specification; the SWP security module is connected with a CLF (Contact-Less Front-end) chip of a mobile terminal through a C6 pin, and transmits the instruction information in line with the SWP. The contact-less communication smart card solves the problem that the same SIM card cannot simultaneously compatible to two current mainstream contact-less mobile payment technical solutions while being respectively inserted into a normal non-NFC (Near Field Communication) mobile phone and a NFC mobile phone.

Description

Technical field [0001] The invention relates to a device in the technical field of wireless communication, in particular to a non-contact communication smart card supporting dual protocols. Background technique [0002] Mobile payment is a way for users to pay for the goods or services they consume through a mobile terminal (usually a mobile phone). The entire mobile payment value chain includes mobile operators, third-party service providers, equipment providers, system integrators, financial institutions, merchants, and end users. [0003] In terms of mobile payment technology, there are currently two mainstream technical solutions on the market: NFC (Near Field Communication) solution based on 13.56M SWP (Single Wire Protocol) and dual interface card based on 13.56M14443 protocol , Both of these methods integrate the radio frequency chip on the SIM card and realize information transmission through radio frequency signals. The difference is that the NFC solution will need to tra...
