Abstract: The Internet of Things,iot is known as the third wave of the world’s information industry following computers and the Internet. The Internet of Things (IoT) is a realization of the “things and Things Connected” network, to achieve the interconnection of everything, everything intelligent, to provide more convenient services, which involves automatic identification technology, in which radio frequency identification (Radio Frequency IDENTIFICTION,RFID) technology is the key.

The strongest enterprise
From the essence of the Internet of things, that is, three levels of demand: automatic identification and mutual communication of front-end entities, Internet networks for data transmission, and intelligent processing of back-end data. Automatic identification and mutual communication of front-end entities is the foundation and focus of the entire IoT architecture. In fact, automatic identification technology began to develop a long time ago, with the continuous development of computer technology, combined with sensor technology, positioning technology and so on to form the core technology of the Internet of things.
Automatic recognition technology is the use of machines to identify entity objects. A simple exposition is the use of identification devices, through the activities between the entity objects, automatically obtain the relevant information of the identified entity objects. For example, in our life, there are many applications of identification technology, supermarket shopping bar code recognition, Alipay WeChat scanning QR code recognition, fingerprint iris and other biometric identification, bank card or credit card recognition, Campus card or bus subway card identification, image recognition technology and radio frequency identification technology.
Radio frequency identification (RFID) is also an automatic identification technology, radio frequency identification through the radio frequency signal to obtain the relevant information of the entity object, and to identify. RFID technology is a non-contact, real-time fast, efficient and accurate acquisition and processing of solid object information automatic identification technology. RFID uses an electronic tag to mark an entity object, using an RFID reader to accept data from an entity object. RFID has strong anti-jamming ability, can identify high-speed moving entity objects, but also can identify the target of entity objects at the same time.
Radio frequency identification technology developed in the the 1940s radar technology, after more than more than 70 years of development, radio frequency identification technology is now widely used in all areas of society. For example, real-time production monitoring and tracking in the manufacturing sector, cargo tracking and courier in the logistics sector, mobile payments in the field of electronic payments, real-time monitoring and tracking in the field of environmental monitoring, interconnection of electronic products in the smart home sector, and many applications in the retail, medical, agricultural and public services sectors.
The development of the Internet of things and RFID technology has now achieved smart cities and smart homes, and the future of smart Earth and perception of China will surely be achieved.
