Multifunctional near field communication integrated system and method

Abstract

The invention relates to a multifunctional near field communication integrated system and a multifunctional near field communication integrated method, which are applicable to near field communication equipment. The multifunctional near field communication integrated system comprises a USB (universal serial bus) encryption chip, an NFC (near field communication) master control chip and an RFID (radio frequency identification) chip; the USB encryption chip is connected with the NFC master control chip through an SPI (serial peripheral interface) control bus, and the NFC master control chip is communicated with the RFID chip through the RF (radio frequency) communication mode; the USB encryption chip is used for realizing the function of a card-issuing card reader; the NFC master control chip is used for realizing the communication type conversion, and the contact communication is converted into non-contact communication; the RFID chip is used for realizing the function of a non-contact card; the USB encryption chip is connected with a PC (personal computer) host through the USB interface, and the PC host carries out read-write authentication and data modification on the RFID chip through the USB encryption chip and the NFC master control chip. With the adoption of the multifunctional near field communication integrated system and the multifunctional near field communication integrated method, the number of cards and USB flash disks carried by users is reduced, the integrated system is convenient and feasible, can be used for issuing cards and also can be used as a card.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a multifunctional near-field communication integrated system and method. Background technique [0002] NFC (Near Field Communication) is jointly developed by Philips, Nokia and Sony based on RFID and interconnection technology. The technical features are low power consumption, simple operation, and RFID compatibility; NFC devices can be used as contactless smart cards and smart cards NFC uses two-way identification and connection for the reader terminal and the device-to-device data transmission link, which can be used for active and passive devices; as a new wireless transmission technology, NFC is mainly used in mobile phone communication, electronic wallets, and identity authentication And other consumer electronics products. [0003] As an identity verification tag, RFID has derived many product forms, but the core functions are similar, and the verification of legal identities...

AI Technical Summary

Problems solved by technology

[0004] NFC technology, RFID, and USB security products are now very mature and flourishing in their respective fields, but there are currently no products with these three characteristics. U-KEY and IC card, etc., also need to carry many things such as ID card, bus card, bank card, shopping card, etc., so it is necessary to search for the check items tediously before going out, and keep digging through a lot of things in the bag to find them after going out Necessary items, people often lose items when they bring a lot of things
