   Generally speaking, labels are basically used to store some basic information of items, such as specifications, number of pieces, purpose, etc.
   What is NFC label? NFC electronic tag is also known as radio frequency tag, smart tag. NFC tag contains NFC chip, using RFID as the basic technology to complete data storage, reading and other operations, data stored in NFC chip. Different from other tags, when we use NFC tags, we usually don't need to see where the tag is, as long as we know where it is. This is because NFC tags communicate with the corresponding NFC reader devices by sending and receiving radio frequencies of a specific frequency, and have penetrability. It doesn't need to expose the tag like bar code tags and laser tags, The corresponding device can scan and read.
   Tell you the structure of NFC label,NFC chip and corresponding antenna are the basic components of NFC tag. Of course, in the actual use process, NFC labels are often packaged in different packages, such as inside the packaging box, inside the bottle cap, etc. RFID technology can be divided into low frequency, high frequency, ultra high frequency and ultra high frequency according to different frequency bands. NFC is a kind of RFID, namely high frequency RFID.
   NFC tag chip accounts for a small proportion, but it is the most complex structure and the highest process requirements. Of course, the design of antenna is also very important, and it must match with the chip. For example, the frequency of NFC chip is 13.56MHz and it follows ISO / IEC 14443a, ISO / IEC 14443b and ISO / IEC 15693 protocols. The antenna design of NFC chip is different from that of UHF RFID chip following ISO 18000.
   So what's the difference between NFC label and ordinary label?
   First, it is unlike bar code and other common tags, which need to read data one-to-one, NFC read-write device can read and write data one to many for corresponding tags.
   Second, the penetration of RF technology make NFC tags can be completely non-contact operation, do not need to expose the tag for scanning.
   Third,NFC label has low environmental requirements, it can work in a variety of harsh environments, the labels are not easy to be damaged, don’t affect reading.
   Fourth, it can be highly accurate, rapid and large-scale recognition, so it can be used in fast moving objects.
Fifth, automation, intelligence, reduce manual operation. NFC tags are also called smart tags, and play an important role in intelligent construction, such as smart home, smart medical, intelligent transportation and other fields.
