Problems solved by technology

The inventor found that in the related art, NFC equipment only supports one kind of information card, for example, supports SE in the SIM card, in this case, if you want to support the information card of the commercial payment institution, you need to replace the terminal, which is very important for the user It means higher cost, and it is not conducive to the promotion of NFC technology
[0005] Aiming at the problem caused by the related technology that the NFC device can only support one kind of information card, no effective solution has been proposed yet

Embodiment approach 1

[0038] In this preferred mode, a switch mode is adopted, figure 2 is a preferred structural block diagram of a near field communication device according to an embodiment of the present invention, such as figure 2 As shown, this preferred device also includes: a switch 22, the switch 22 is connected with the first card slot 12, the second card slot 14 and the NFC chip 16, and by the selection of the switch 22, the NFC chip 16 can pass the first card slot 12 and the second card slot The first connection established by an information card may also establish the second connection with the second information card through the second card slot 14 .

[0039] In this preferred implementation manner, only one hardware switch is needed to switch the connection, and the implementation is relatively simple. As another implementation, figure 2 The switch shown in can also represent a software function, that is, the NFC chip 16 is physically connected to the first card slot 12 and the s...

Embodiment approach 2

[0042] In this preferred embodiment, a switch is not used, and an NFC chip with at least two interfaces is provided, image 3 is a preferred structural frame of the near field communication device according to the embodiment of the present invention Figure II ,Such as image 3 As shown, the NFC chip 16' at least includes: a first interface connected to the first card slot 12 and a second interface connected to the second card slot 16; the NFC chip 16' is used to receive a control signal, and the control signal is used for It indicates that the NFC chip 16 ′ is connected to the first information card through the first interface and the first card slot 12 or is connected to the second information card through the second interface and the second card slot 14 .

[0043] In this preferred embodiment, no additional switch is needed, and the use of an NFC chip with at least two interfaces can be understood as the function of the switch is built into the NFC chip, so that the NFC ch...

Embodiment approach 3

[0045] A special NFC chip is used in the second preferred embodiment, which requires the support of the NFC chip manufacturer, or the specific NFC chip needs to be customized. Taking this into consideration, another implementation is provided in this preferred embodiment, in which NFC chips equal to the number of information cards are used, Figure 4 is a preferred structural frame of the near field communication device according to the embodiment of the present invention Figure three , the figure only shows two card slots symbolically, such as Figure 4 As shown, the NFC chip is actually a plurality of NFC chips, including: at least one first NFC chip 162 connected to the first information card through the first card slot 12, and at least one connected to the second information card through the second card slot 14 connected second NFC chip 164, wherein the first NFC chip 162 and the second NFC chip 164 are used to receive a control signal, and the control signal is used to ...

Abstract

The invention discloses a near-field communication device and method. The device comprises: at least one first card slot for inserting a first information card, wherein a security unit is stored in the first information card; at least one The second card slot, the second card slot is used to insert the second information card, wherein, the second information card stores a security unit; the near field communication chip is used to communicate with the first information card through the first card slot or through the second The card slot is connected with the second information card. The present invention solves the problem that the near-field communication device can only support one kind of information card, and further realizes the support for multiple information cards.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a near field communication device and method. Background technique [0002] Near Field Communication (NFC for short) is a short-range wireless communication technology evolved from Radio Frequency ID (RFID for short), and is currently mainly used in mobile payment functions. In order to ensure the security of payment transactions, NFC devices (for example, mobile phones) need to have a secure element (SecureElement, referred to as SE). [0003] Among the NFC payment solutions in the related art, there is one that builds the SE into a Subscriber Identity Module (Subscriber Identity Module, SIM for short) card. Since the SIM card is issued by the operator, the operator leases the secure space in the SIM card to a commercial payment institution and charges rent. This implementation may make the commercial payment institution subject to the operator. [0004] Commercial payment ...
