Technology behind IOT

The technology used in making Internet of Things is Electronic Product Code (EPC), Radio Frequency Identification (RFID) and EPCglobal Networks.

EPC is a unique number on every item, which becomes the identity of the item. It is like a barcode on every item, only difference being that it is associated with dynamic data of the item. Unlike the barcode, which has only the product category, it holds the identity of the item through the unique features of the item, like date of production or independent serial number. This makes the item equipped enough to be tracked throughout its journey, from the manufacturer to the buyer. RFID is a wireless technology, used to store and process information, modulate radio frequency signal and transmit and receive signals. The EPC, along with the RFID chip is stored on an RFID tag. The RFID chip transmits the information of EPC through EPCglobal Network. The EPCglobal Network comprises of the devices and services used for automatic identification and immediate transfer of information on the items (EPC). These devices include the EPC Readers and EPC tags, EPC Middleware and EPC Services, for smooth and undisruptive transmission of information.
