NFC has the characteristics of quick and convenient connection, low cost, small volume and the like, and is widely carried on a plurality of mobile phones, commercial equipment and IOT equipment. NFC tags of current NFC devices are generally static, i.e. tag data is statically stored in an NFC sector. After the NFC reader (e.g., a mobile phone supporting NFC communication) approaches the target NFC device, data in the target NFC tag sector may be read, and tag data may be obtained. The tags are often statically stored in the tags when the devices leave the factory, the tags are required to be rewritten and changed once the connection information is changed, maintenance is not easy, the erasing times of the NFC sector are usually limited, and the method cannot be suitable for a scene of dynamically transmitting data between two devices.
Currently, the size of data transmission of an NFC tag is generally limited to be less than 8KB, and excessive data size can cause frame loss in NFC communication, which results in transmission failure due to too high communication error rate. The transmission data size of the service data is often far higher than the limit, so that it is necessary to propose a transmission method that can realize a larger data size. At present, NFC tags can be used for realizing static storage of one URL in an NFC tag sector, and an NFC reader-writer interacts with a server to perform more service interaction and information acquisition by reading static URL information. In this way, the URL is a static address, and after the NFC reader reads the URL and connects with the URL, the NFC reader cannot directly obtain the required dynamic data, and often, some additional operations are required by the user. Therefore, a more flexible and stable transmission mode of the large-data-volume dynamic NFC tag needs to be designed.
