IOT and RFID
The Internet of Things uses information sensing equipment such as radio frequency identification (RFID technology), infrared sensors, global positioning systems, laser scanners and gas sensors to connect each item to the Internet for information exchange and communication, intelligent identification, positioning, tracking, Monitor and manage the network. In short, the Internet of Things is the Internet of Things.
RFID technology, also known as radio frequency identification, is a communication technology that uses wireless signals to identify specific targets and read and write related data without the need for mechanical or optical contact between the identification system and the specific targets. For example: access control systems that do not require a swipe card
If you want to summarize in sentences, I think RFID technology is one of the basic technologies of the Internet of Things.
1. What is RFID technology
First of all, RFID technology is the abbreviation of English Radio Frequency Identification, and Chinese is radio frequency identification.
The RFID technology here refers to the target such as readers and tags being read and written.
According to this information, this technology is also called radio frequency identification, a type of communication technology, which is characterized by the ability to identify targets and read and write data through radio signals, without the need for identification equipment to establish a contact relationship with the identification target. This function is very simple: it can send data without touching it. This data is an identifier. It can not only read data but even write data.
2.What is the Internet of Things?
Literally, the Internet of Things is a "Internet of Everything." If you think you can't explain it, look at the English language, which is: Internet of things (referred to as IoT), which is the network between objects.
Specifically, the Internet of Things uses communication technologies such as local networks and the Internet to connect sensors, controllers, machines, people, and things in new ways, thereby enabling people, things, and information to communicate with each other. Form remote management control and intelligent network.
The core idea is information sharing and intelligent (smart) processing of information.
The premise of intelligent information processing is to achieve information sharing, and the premise of information sharing is to own (or have collected) information. Also called big data.
