Double-frequency multi-protocol multifunctional near field communication integrated system and application method

摘要: The present invention discloses a type of integrated system and application method for dual-frequency multi-protocol multifunctional near field communication. A first inductive antenna is connected to high-frequency NFC card-reader chip; the chip reads information tag, tag transmitted smart terminal by an ARM main-control through Bluetooth module; at module, also dual-interface smart-card chip, matching with second antenna, emulated into tag; low-frequency read third card-emulation control achieve functions cards, deploying cards under any formats protocols. covers high/low-frequency RFID applications, extends functions, facilitates switching between mode card mode, improves quality experience functions.
