RFID Based Smart Car Parking And Security System Using Arduino

Radio Frequency Identification [RFID] system is evolving as a major technology in Automation System in Malls/Buildings/Industries or in the medical field in order ncrease efficiency and security. Typically RFID comprises of two parts. First is the RFID reader/Interrogator and the second is the RFID transponder. Transponder may be smart cards or tags or key chains or any other electronic devices. RFID technology is the advanced method of barcode method. RFID system uses electromagnetic fields (radio waves) in order to transfer data for performing automatic detection and tracking of different tags or different objects from some distance. RFID system is an Automatic Identification and Data Capture (AIDC) technology used to identify, capture, track and store the data present in the tag. The main objective is to providea system with security. In this paper we have proposed contactless smart cards in order to limit the unauthorized vehicles to enter into the parking area. Each card has unique information stored in it and if it comes nearer to the reader then RFID reader scans the information present in the card and sends this information to the database (stores the data present in the tag) and displays the relevant information on LCD. If the reader has details about that tag in the database then gate is opened automatically for authorized vehicle to enter into the parking lot, If not gate will be closed and alerts through a buzzer for unauthorized vehicle.
