Abstract

Background/Objectives: To locate misplaced objects using RFID technique. Methods/Statistical Analysis: RFID is Radio Frequency Identification. This technique is most suitable for indoor positioning of objects. RFID technology consists of RFID tags, RFID reader and a user interface. HT12E is the encoder which is present in the transmitter. The RFID tag consists of transmitter. The HT12D Decoder is present in the receiver. The reader consists of HT12D Decoder. The communication takes place between the tag and reader. The GLCD i.e., graphical LCD shows the result. If the object is missing then it is shown in graphical LCD. Findings: The objects such as keys, remotes, wallets etc., can be found easily using this technique in our smart homes. This is an indoor restriction innovation. Application/Improvements: RFID innovation is most broadly utilized innovation however because of a few difficulties this innovation can’t be market satisfactory. Additionally it is most suitable innovation for indoor situating in light of the fact that other following frameworks, for example, GPS can’t be utilized for indoor situating since it doesn’t get signal from satellites. Radio Frequency Identification (RFID) is a quickly developing innovation that can possibly have effects on numerous commercial projects.
