Problems solved by technology

[0002] The current communication speed of Near Field Communication (NFC) is divided into multiple speeds such as 106kbps, 201kbps, 424kbps, etc. In a small amount of NFC data communication, it is not necessary to consider the communication efficiency, often only one data frame is needed The data transmission can be completed, but when a relatively large data is transmitted (such as multiple frames are required to complete the transmission), it takes a long time to write data at a lower communication rate (such as 106kbps)

Embodiment Construction

[0025] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0026] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, relative terms such as "first", "second", etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that these entities or operations, any such actual relationship or order exists. Furthermore, the term "comprises", "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus comprising a set of elements includes not only those elements, but also includes elements not...

Abstract

The invention relates to a data writing method, an NFC tag, an NFC device and a storage medium, and belongs to the technical field of near field communication. The method includes: receiving an instruction header sent by an NFC device, the instruction header carries an instruction keyword, a data frame and a write address; if the instruction keyword is a write instruction and the data frame is not the last frame of data, sending The device feeds back the message that the simulated data frame is written successfully, writes the data frame to the write address, and feeds back the real writing result of the data frame to the NFC device when receiving the next frame of data. In the embodiment of the present application, by changing the existing NFC data writing method, it is no longer sending a write data command, waiting for the data to be written successfully before sending the next data command, but adopting a dislocation writing method, that is When a write data command is received, the simulated frame data write success message is fed back immediately, so as to reduce the waiting time for data writing and improve the writing efficiency.

Description

technical field [0001] The invention belongs to the technical field of near field communication, and in particular relates to a data writing method, an NFC tag, an NFC device and a storage medium. Background technique [0002] The current communication speed of Near Field Communication (NFC) is divided into multiple speeds such as 106kbps, 201kbps, 424kbps, etc. In a small amount of NFC data communication, it is not necessary to consider the efficiency of communication, and often only one data frame is needed. The data transmission can be completed, but when a relatively large data is transmitted (such as multiple frames are required to complete the transmission), it takes a long time to write data at a lower communication rate (such as 106kbps). Contents of the invention [0003] In view of this, the object of the present invention is to provide a data writing method, NFC tag, NFC device and storage medium to improve the problem that it takes a long time to transmit a rel...
