Radio-Frequency Identification (RFID) makes utilization of EM waves to differentiate and track labels joined to objects naturally. It uses labels or tags in the object which are to be tracked or identified. Readers (transmitter and receiver which can work both the ways) send a signal directed towards the tag and then read its response. These tags have date or information stored in them electronically. These tags receive the signal and then in turn respond back to it with information. They are different in relation to standardized tag like barcodes because they don’t require being inside the viewable pathway of the reader. As of late, RFID has began to play role in many of the applications that help in accelerating the process of handling goods. These RFID tags not being big in size can be incorporated in the consumer products and also implanted inside pets. A RFID tag could likewise be appended to a vehicle amid its creation and afterward it can be used to keep check on its development through this system. An RFID tag may also be incorporated within an automobile during its production and then it can track the progress of the automobile. This proposed RFID using Arduino has multiple applications, scope of which has been described further.
