Problems solved by technology

[0004] At present, the NFC products on the market integrate or insert the NFC chip inside the smart phone. When the NFC mobile terminal performs mobile payment based on NFC technology, it is usually necessary to bind the user's personal information to the NFC chip. In this way, with NFC If the smart phone with the chip is lost, the user's personal information is easily stolen, which will cause economic losses
[0005] In addition, there is another external NFC device connected through the USB interface of the smart phone on the market. This external NFC device needs to be connected with the USB interface of the mobile phone during specific use. The data channel affects the operation of other data interaction using the data channel of the mobile phone

example 1

[0044] Example 1: When a user holding an NFC system needs to make a mobile payment for consumption, the signaling interaction process between the external identification device and the NFC system, such as image 3 shown, including the following steps:

[0045] S301. Bring the external NFC device close to a reading device such as a POS machine or other NFC devices, and the reading device sends a radio frequency signal to the external NFC device;

[0046] S302. The label circuit of the external NFC device sends a radio frequency signal carrying the first UID code to the identification device, and at the same time transmits the first UID code to the microprocessor;

[0047] Wherein, the first UID code is a globally unique ID code pre-stored in an external NFC device, which is previously associated with the private information of the user holding the mobile terminal (such as: the user's ID number, mobile phone number, bank number, work unit, home address and usual consumption, et...

example 2

[0066] Example 2: When the NFC system charges other consumers, the signaling interaction process between other NFC devices and the NFC system, such as Figure 5 shown, including the following steps:

[0067] S501. The reading circuit of the external NEC device continuously sends radio frequency identification signals to the outside;

[0068] S502. When other NFC devices are close to the external NFC device, the reading circuit of the external NFC device receives the radio frequency signal carrying the second UID code sent by the other NFC device. The private information of the consumer user of the NFC device (such as: the consumer user's ID number, mobile phone number, bank number, work unit, home address, and usual consumption situation, etc.) is associated.

[0069] S503. After receiving the second UID code, the reading circuit transmits the second UID code to the microprocessor; after receiving the second UID code sent by the reading circuit, the microprocessor stores the ...

Abstract

The invention discloses a near field communication (NFC) system and mobile payment and charging methods thereof. The system comprises a mobile terminal with headset jacks, and an external NFC device with a plug, wherein the external NFC device executes data communication with the mobile terminal through a headset data channel, so that payment and charge functions of the mobile terminal are realized; in the process, a universal serial bus (USB) interface of the mobile terminal is not occupied, and other data interaction operations of a user with the USB interface cannot be influenced; the NFC system is convenient to use; furthermore, a unique identification (UID) code stored in the external NFC device can be associated with personal information of the user holding the mobile terminal, so that under the condition that the external NFC device is matched with the mobile terminal, the mobile payment or charge function can be successfully realized; therefore, the potential safety hazard because of leakage of the personal information of the user caused by loss of the mobile terminal or the external NFC device is avoided; and the safety is high.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an NFC system and its mobile payment and charging methods. Background technique [0002] Near Field Communication (NFC, Near Field Communication) technology is a new technology evolved from the fusion of Radio Frequency Identification (RFID, Radio Frequency Identification) and interconnection technology, and it is a short-distance wireless communication technology. It integrates a contactless card reader, a contactless smart card and point-to-point functions on a single chip, can run in the frequency range of 13.56MHz, and can establish a connection between devices within a range of about 10cm, and the transmission rate It can reach 106Kbit / s, 212Kbit / s or 424Kbit / s, and it is expected to increase to more than 848Kbit / s in the future. [0003] There are two main working modes of the NFC terminal: (1) Active mode: In this mode, the NFC terminal acts as a card reader and acti...
