Embodiment 1

[0044] In this embodiment, if figure 1As shown, the base card 1, that is, the SIM card or UIM card has a copper interface 7 that can be matched with the mobile phone card holder, which fully complies with the ISO7816 standard. The base card 1 is integrated with: CPU processor 8, memory 2, first The radio frequency transceiver circuit 3 and the second radio frequency transceiver circuit 4 . The first antenna 5 and the second antenna 6 are respectively connected with the first radio frequency transceiver circuit 3 and the second radio frequency transceiver circuit 4, wherein the first antenna 5 and the second antenna 6 can be external antennas or built-in antennas, However, the more preferred first antenna 5, that is, the NFC antenna with a frequency of 13.56M is preferably external, which can be drawn out through a copper interface, or can be designed on the PCBA board of the mobile phone. The whole circuit is correspondingly connected with the corresponding end points of the ...

Embodiment 2

[0056] As shown in FIG. 7 , in this embodiment, the mobile phone with NFC and 2.4GHz dual-band communication performs data transmission with the service terminal (POS machine) in a radio frequency manner. The mobile phone is equipped with a SIM / UIM card with both NFC and 2.4G dual-band communication, which performs information interaction processing with the service terminal through NFC and 2.4G frequency bands.

[0057] The business platform is the processing platform for the mobile card business. It is mainly responsible for the business processing and management of the card, such as access control, attendance, garage, ETC, VIP card, information release and collection, electronic certificates, tickets, etc., to process and manage business information, General platform for publishing and collecting business information;

[0058] The payment platform is a payment and settlement platform for operators and third-party payment companies. It mainly handles the management and opera...

Abstract

The invention discloses an intelligent card combining NFC and 2.4G double frequency band communication and a double frequency band communication system, which are mainly designed for providing the intelligent card combining NFC and 2.4G double frequency band communication and the double frequency band communication system. The intelligent card comprises a base card, a CPU (Central Processing Unit) processing module, a first radio frequency transceiver circuit, a second radio frequency transceiver circuit, a first antenna and a second antenna which are integrated on the base card, wherein the signal transceiver end of the first radio frequency transceiver circuit is connected with the first antenna; the first antenna is used for transmitting and receiving data information of 13.56MHz frequency band; the signal transceiver end of the second radio frequency transceiver circuit is connected with the second antenna; the second antenna is used for transmitting and receiving data informationof 2.4GHz frequency band; the CPU processing module is respectively connected with the first radio frequency transceiver circuit and the second radio frequency transceiver circuit; the frequency of received or emitted data information is identified; and according to the identification result, a control order is output to control the first radio frequency transceiver circuit or the second radio frequency transceiver circuit to interactively communicate data according to a preset frequency.

Description

technical field [0001] The invention relates to the field of NFC and 2.4G frequency band communication, in particular to a smart card and a dual frequency band communication system having both NFC and 2.4G dual frequency band communication. Background technique [0002] As a short-range wireless communication technology, NFC (Near Field Communication) has some obvious advantages, such as extremely low power consumption, good security, and the speed can generally meet the requirements of point-to-point information exchange, content access and service exchange between two devices. For applications requiring higher bandwidth such as audio and video streams, it can cooperate with technologies such as Bluetooth and wireless LAN to provide a convenient and automatic access function. NFC is compatible with existing contactless smart card technology and has become an official standard supported by more and more major manufacturers. However, technical solutions based on NFC mobile p...
