Abstract

The present invention discloses a method and device for transmitting NFC data, including: when a first near-field communication NFC terminal receives a data transmission instruction, acquire a first terminal identifier and an encrypted terminal identifier of the first NFC terminal; wherein, the encrypted The terminal identifier is encrypted data obtained by encrypting the first terminal identifier with a key corresponding to the first terminal identifier; The data carrier is sent to the second NFC terminal in a data transmission message.

Description

technical field [0001] The invention relates to electronic technology, in particular to a method and device for transmitting NFC data. Background technique [0002] Smart mobile terminals provide many ways for data transmission, from wired to wireless, and provide a lot of convenience for user's device interaction. Near Field Communication (NFC) is one of the more and more frequently used interaction methods. Among the various wireless technologies supported by terminal equipment, the range of NFC is the shortest, usually no more than 20 centimeters. It is precisely because of the relatively short distance that the default data transmission of terminal devices is based on trust and security. Therefore, the implementation of NFC data transmission in the terminal device is relatively simple. The kernel driver talks to the NFC hardware. The data is passed to the NFC service of the Android framework layer. The NFC service does not perform any verification on the received dat...
