the step of reading space-time coding information by radio frequency identification comprises the following steps:
step 7: searching and searching all radio frequency identification tags nearby;
step 8: reading all unprocessed data in the radio frequency identification tag through the radio frequency identification reader-writer;
step 9: decrypting and transcoding the unprocessed data into natural language recognizable data through a PC (personal computer) end;
step 10: and updating the related data in the cloud server.
