RFID is a simple technology that allows any object (OOI) to be identified. The use of RFID tags with unique identification codes, in addition to simply attaching the tags to the entity, easy to embed the tags in the object (OOI) for identification. RFID is a wireless radio frequency technology, which is transmitted through the antenna between the tag and the reader. In this way, related information on the label of the object (OOI) can be easily obtained.
When the circuit in the RFID tag has sufficient energy, it will start signal transmission and connection within the range of the reader. This method is different from other static identification technologies. It is a LOUD ID technology. This feature makes some inventory management and positioning issues very simple, which is why RFID can be perfectly used in tracking, tracing and inventory management functions.
