Abstract
A near field communication (NFC)-based data transmission method and apparatus, and a near field communication device. An NFC touch apparatus sends an intelligent extraction instruction to a first NFC device, to trigger the first NFC device to perform intelligent extraction processing on to-be-transmitted data determined by the first NFC device to obtain intelligently extracted data, receives the intelligently extracted data that is sent by the first NFC device by means of NFC communication and sends the intelligently extracted data to a second NFC device by means of NFC communication. A size of the NFC touch apparatus is smaller than sizes of the first NFC device and the second NFC device, so that an NFC antenna of the NFC touch apparatus and an NFC antenna of the first NFC device as well as an NFC antenna of the second NFC device are easily within an effective communication range.
