The RFID sub-tag comprises an RFID chip, a tag manufacturer data storage area, a tag user data storage area and an article data storage area, wherein the RFID chip of the RFID sub-tag is internally provided with a memory which is written once and read for many times, the memory is internally provided with a tag manufacturer data storage area, a tag user data storage area and an article data storage area, the tag manufacturer data written in the tag manufacturer data storage area and the tag user data written in the tag user data storage area are plain data and can be read and decoded by a general ultrahigh frequency RFID reader, the article data written in the article data storage area are encrypted data, and the encryption is performed by an encryptor of. The data of the coding area of the article must be specially decrypted to analyze the article code. The decryption can be carried out in an ultrahigh frequency RFID reader area, and the decryption can also be carried out in a remote cloud server by the ultrahigh frequency RFID reader through remote communication of data. The tag manufacturer data is a tag manufacturer code, the tag user data is a tag user code, and the item data is an item code. The data of the tag manufacturer data storage area, the tag user data storage area and the article data storage area are written in when the RFID tag is delivered from a factory, and the data stored in the memories of all the RFID sub-tags are consistent. During assembly, different RFID sub-tags are spatially arranged at a predetermined angle with respect to each other in the sensing direction, the predetermined angle interval ranging from [10 °,90 ° ].
The label assembling method of the label comprises the following steps: all the labels are stuck on the same surface of the package with the approximate middle point as the cross point and overlapped with the sensing direction at a preset angle, as shown in fig. 3, but of course, the labels can also be stuck with the middle point as the cross point. All the labels can also be pasted on different surfaces of the package at a preset angle according to the sensing direction in space, as shown in fig. 4, wherein one or more labels can be pasted on one surface.
