Embodiment 1

[0035] Embodiment 1. An application example of the mobile phone radio frequency SIM card compatible with the SWP function in an NFC mobile phone.

[0036] Such as image 3 As shown, the mobile phone radio frequency SIM card 201 compatible with the SWP function of the present invention is placed in the NFC mobile phone 101 . During the power-on process of the mobile phone, the SIM micro-control unit 103 of the mobile phone radio frequency SIM card 201 compatible with the SWP function also enters the state of power-on, and through the ISO / IEC7816 interface 106, via the SIM card contact 104, the mobile phone baseband and The ISO / IEC7816 interface 110 between the contacts of the SIM card establishes communication with the baseband 108 of the mobile phone to confirm the basic functions of the mobile phone. Thereafter, the SIM micro-control unit 103 starts to send an "inquiry" command to the NFC CLF107 through the SWIO interface 105 on the SIM card, via the SIM card contact 104, th...

Embodiment 2

[0037] Embodiment 2, the application example of the mobile phone radio frequency SIM card compatible with SWP function in non-NFC mobile phones.

[0038] Such as Figure 4 As shown, the mobile phone radio frequency SIM card 201 compatible with the SWP function of the present invention is placed in the non-NFC mobile phone 401 . During the power-on process of the mobile phone, the SIM micro-control unit 103 of the mobile phone radio frequency SIM card 201 compatible with the SWP function also enters the state of power-on, and through the ISO / IEC7816 interface 106, via the SIM card contact 104, the mobile phone baseband and The ISO / IEC7816 interface 110 between the contacts of the SIM card establishes communication with the baseband 108 of the mobile phone to confirm the basic functions of the mobile phone. Thereafter, the SIM micro-control unit 103 starts to send an "inquiry" command to the mobile phone via the SIM card contacts 104 through the SWIO interface 105 on the SIM ca...

Abstract

The invention discloses a mobile phone radio-frequency SIM card with an SWP function in a compatible mode. The mobile phone radio-frequency SIM card comprises an SIM micro-control unit, an SIM card contact point, an SWIO interface between the SIM micro-control unit and the SIM card contact point and an ISO/IEC 7816 interface signal line between the SIM micro-control unit and the SIM card contact point. The mobile phone radio-frequency SIM card further comprises a radio-frequency module, an SIM antenna connected with the radio-frequency module and a wired interface connected with the SIM micro-control unit and the radio-frequency module. The functions of mobile payment, ticket identification and identity recognition can be achieved for a NFC mobile phone or a non-NFC mobile phone without any modification of the mobile phone self.

Description

technical field [0001] The present invention relates to the field of mobile phone SIM (Subscriber Identity Module, customer identification module) card design and the field of wireless communication, in particular to a method for realizing a mobile phone radio frequency SIM card compatible with SWP (Single Wire Protocol, single wire protocol). Background technique [0002] With the continuous development of financial networks, financial consumption tools such as POS machines have penetrated into every corner of daily life such as home, work and travel. The mobile phone is an indispensable portable mobile terminal in modern human life. Integrating functions such as payment, ticket and identification into the mobile phone has become a new hot spot in the mobile phone and its surrounding industries in recent years. [0003] Among a wide variety of mobile payment solutions, solutions based on NFC (Near Field Communication) mobile phones and SWP SIM cards have gradually become po...
