Problems solved by technology

[0005] The data communication method in the prior art that combines NFC technology with other transmission methods does not realize data transmission based on NFC technology in the true sense.
In addition, there are security risks in transmission methods such as Bluetooth and WIFI technology, which cannot guarantee the security of payment business applications
For business operations, relying too much on terminal configuration and environmental factors has led to uncertainty in the operation of NFC as a service

Embodiment 1

[0055] figure 1 A flow chart of an NFC communication method provided by Embodiment 1 of the present invention, such as figure 1 As shown, the NFC communication method is based on an intelligent information terminal with an NFC chip, and is used to send large-capacity raw data to the intelligent terminal with a smart card only by using the NFC chip. The NFC communication method includes:

[0056] Step 101: Establish an NFC permanent connection link with the smart terminal.

[0057]Different from the short connection mode used in the prior art for NFC communication, in the present invention, the intelligent information terminal establishes an NFC long connection link with the intelligent terminal through the first link establishment module. Based on the NFC long connection link, the NFC chip can continuously send multiple data packets conforming to the NFC communication standard.

[0058] Step 102: Split the original data packet into several sub-data packets.

[0059] Based o...

Embodiment 2

[0067] figure 2 A flow chart of an NFC communication method provided in Embodiment 2 of the present invention, such as figure 2 As shown, the NFC communication method is based on an intelligent information terminal with an NFC chip, and the NFC communication method includes:

[0068] Step 201: Perform identity authentication on the smart terminal.

[0069] In step 201, the smart information terminal acquires the identity information of the smart terminal, and performs identity authentication on the smart terminal based on the acquired identity information.

[0070] Among them, when the smart card in the smart terminal contains an NFC chip, the smart terminal can store its identity information in the form of an NFC static tag. At this time, the NFC chip in the smart information terminal can be in the card simulation mode to read the static Identity information in the label. When the smart card in the smart terminal does not contain an NFC chip, the identity information can...

Embodiment 3

[0084] image 3 A flow chart of an NFC communication method provided in Embodiment 3 of the present invention, such as image 3 As shown, the NFC communication method is based on an intelligent terminal with a smart card, and is used to obtain a large-capacity data packet from an intelligent information terminal with an NFC chip. The NFC communication method includes:

[0085] Step 301: Establish an NFC permanent connection link with an intelligent information terminal.

[0086] In step 301, the intelligent information terminal and the intelligent terminal will negotiate some control information in the data communication process, such as: the duration of the NFC long-connection link, the splitting algorithm of the original data packet, the integration algorithm of the sub-data packet, and Based on the negotiation result, a corresponding NFC permanent connection link is established between the smart terminal and the smart information terminal.

[0087] Step 302: Receive sever...

Abstract

The invention discloses an NFC communication method, an intelligent information terminal, an intelligent terminal and an NFC communication system, wherein the NFC communication method includes: establishing an NFC long connection link with an intelligent terminal; splitting an original data packet into several sub-data packets: Each sub-data packet is sent to the smart terminal sequentially through the NFC long connection link, so that the smart terminal receives all the sub-data packets and integrates all the received sub-data packets into an original data packet. The technical scheme of the present invention can realize sending large-capacity original data packets to intelligent terminals only based on the NFC chip. In the present invention, because the transmission of the original data packet is only based on the NFC protocol, it has relatively high security. In addition, the NFC communication method is not only applicable to smart terminals with NFC chips, but also to smart terminals without NFC chips, thus breaking through the limitations of terminals and environmental factors, and effectively expanding the NFC capabilities of smart terminal users without NFC chips. The usage mode is conducive to the smooth transition of the user.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an NFC communication method, an intelligent information terminal, an intelligent terminal and an NFC communication system. Background technique [0002] As a competitive short-distance wireless communication technology, Near Field Communication (NFC) has the advantages of short communication distance, short connection establishment time, low energy consumption requirements, high security, simple network topology, and low cost. , easy to use and intuitive, and compatible with the existing contactless smart card technology, it is very suitable for contactless services applied to mobile smart terminals, and realizes the rapid exchange of important data such as financial information or sensitive personal information.
