IoT is the current mainstream trend in technology. In this way, we will discuss the industrial changes and market opportunities of the digital revolution, and will further analyze the technology and application fields of IoT.
Radio Frequency Identification (RFID) is a technology used to identify items in unique manner by way of radio waves, and is capable of capturing hundreds of objects at the same time. Although the term of RFID is not often heard, we use it in our daily lives more than we imagine, and its use continues to increase.
