Description
Technical Field
The invention relates to the technical field of electronic wallets, in particular to an NFC-SIM card supporting the electronic wallet, a system and a transaction processing method.
Background
At present, the electronic hard wallet usually relies on a chip, and the electronic hard wallet exists in the form of a card or a car key, so that carrying and payment are inconvenient. With the development of third-party payment software of mobile phones, more and more complex operations can be completed through mobile intelligent devices (such as mobile phones). If the electronic wallet is added into the mobile intelligent device, the safety and the use convenience of the electronic wallet can be enhanced.
Chinese utility model patent publication No. CN212034112U discloses an independent security card and a terminal device for using the independent security card, wherein the independent security card includes a microprocessor, a communication module and an interface; the communication module comprises an NFC communication unit; the microprocessor is used for receiving the data operation instruction from the communication module, carrying out corresponding processing according to the data operation instruction to obtain response data and sending the response data to the communication module; the interface comprises an antenna contact which is connected with an external NFC antenna; the communication module is used for receiving a data operation instruction of the external equipment and sending response data to the external equipment. According to the scheme, the new equipment can be protected by the safety scheme only by taking the independent safety card out of the old equipment and inserting the independent safety card into the contact type card slot of the new equipment. However, on the one hand, for a mobile smart device with only a single contact card slot for installing a SIM card, when using the e-wallet transaction function, the SIM card needs to be taken out of the contact card slot, and then a separate security card in the shape of the SIM card needs to be inserted into the contact card slot, which makes the mobile smart device unable to have both the communication function and the transaction function of the SIM card. On the other hand, the scheme needs to provide electric energy for the mobile intelligent device and the independent safety card through the power module of the mobile intelligent device, and electronic wallet transaction cannot be realized under the condition that the mobile intelligent device is not powered. In addition, if the NFC communication unit in this scheme is fixedly connected to the power contact, the NFC communication unit is in an active power state, and if the NFC module of another external device is also in the active power state, the NFC communication unit and the NFC module interfere with each other, and normal communication cannot be performed, that is, it is impossible to normally implement "touch and touch" of the mobile smart device to complete a transaction.
