Abstract

The invention discloses an NFC card system with an additional separate Bluetooth adapter. The system comprises the Bluetooth adapter and an NFC card. The Bluetooth adapter comprises a Bluetooth module, a power supply component and an ISO7816 interface module. When the NFC card needs to perform Bluetooth wireless communication, a contact interface thereof is connected with the Bluetooth adapter through a plug-in, and the NFC card is used independently generally. The device realizes Bluetooth transmission when the NFC card needs to be wirelessly updated in the air, and can also communicate witha NFC-compliant device, and supports various interfaces of the NFC card, thus enhancing the application scene of the NFC card.

Description

technical field [0001] The invention relates to an NFC card system with a separate bluetooth transfer accessory, which is used in the fields of safe payment, safe transaction and safe communication. Background technique [0002] Near Field Communication (NFC) is a short-range, high-frequency wireless communication technology that allows simple interaction between multiple devices. NFC technology evolved from the integration of non-contact radio frequency identification and interconnection technologies. It combines the point-to-point functions of inductive card readers and inductive card boxes on a single chip, and can identify and exchange data with compatible devices within a short distance. Different from RFID, NFC technology has the characteristics of two-way connection and identification, works at 13.56MHz, and has a working distance of about 10 cm. [0003] The existing NFC card has a contact interface and a non-contact interface, wherein the contact interface meets th...
