Problems solved by technology

[0003] Common mobile payment functions rely entirely on the security module inside the mobile phone to ensure payment security, which is relatively poor in security
For example, when the mobile phone holder loses the mobile phone, there is still a risk of payment being stolen

Embodiment Construction

[0016] As shown in the accompanying drawings, the NFC-based electronic payment device includes:

[0017] A mobile phone and a portable matching device.

[0018] The mobile phone includes an AP and a first NFC module, and the AP and the first NFC module communicate through an SPI or I2C standard interface. The portable matching device includes a second NFC module.

[0019] The first NFC module and the second NFC module communicate wirelessly through a radio frequency antenna.

[0020] The first NFC module keeps inquiring whether there is a second NFC module approaching from outside. When there is a second NFC module approaching, the second NFC module will respond to the first NFC module, and the two will formally establish communication; the second NFC module will respond to data After being packaged in accordance with the ISO14443A / B, ISO18092 and ISO21481 protocols, the data is sent to the first NFC module through the radio frequency antenna.

[0021] After the first NFC module recei...

Abstract

The invention discloses an electronic payment device based on NFC. The electronic payment device comprises a cell phone and a matching device, wherein the cell phone comprises an AP and a first NFC module, the AP and the first NFC module are in communication through an SPI or I2C standard interface, the matching device comprises a second NFC module, the first NFC module and the second NFC module are in wireless communication through a radio frequency antenna, the second NFC module sends data to the first NFC module after packaging the data according to a protocol ISO14443A/B, a protocol ISO18092 and a protocol ISO21481, the first NFC module sends data to the AP after packaging the data according to the protocol ISO14443A/B, the protocol ISO18092 and the protocol ISO21481. The AP analyzes the data to decide whether a user has the right to pay. By means of the electronic payment device, the security of electronic payment can be improved.

Description

Technical field [0001] The invention relates to the field of mobile phone product design and NFC communication, in particular to an electronic payment device based on NFC. Background technique [0002] Near Field Communication (NFC), also known as Near Field Communication, evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID. NFC technology is a short-distance high-frequency wireless communication technology that allows non-contact point-to-point data transmission between electronic devices within a distance of ten centimeters to realize data exchange. Due to the natural security of NFC technology, it is particularly suitable for providing M2M (Machine to Machine) communication for handheld devices such as mobile phones, and is considered to have very broad prospects in payment applications for handheld devices such as mobile phones. [0003] Common mobile phone payment functions rely entirely on the security module inside the mobile ...
