The goal of Internet of Things is to combine the virtual and physical world. Everyday objects can learn to "think" and communicate with each other over the Internet. The stand-alone computer is being replaced more and more by "intelligent things," or many smaller computers in objects.
This concept works over "Radio Frequency Identification" (RFID). This small electronic data storage or transponder is installed in various objects and can be read or written by using radio waves. Each transponder contains a specific number called "Electronic Product Code" (EPC), with which the respective object can be uniquely identified worldwide. With RFID technology, an object can be read remotely and tracked individually from a great distance. Depending on the radio frequency, it can be reached up to several hundred meters in range. Today this technique is applied in different contexts, such as toll systems, animal identification in agriculture or electronic locks.
