Arduino Based Smart RFID Security and Attendance System with Audio Acknowledgement

there has been emerging demand for secure system that must be reliable and fast responded for the industries and company. RFID (Radio Frequency Identification) is one of the reliable and fast means of identifying any material object. Their significant advantage are that they can read wirelessly, contain more information than barcode and more robust in nature and based on non-line-of-sight technology. RFID tags can read in any environmental challenging conditions where other read technology likes barcode or optical card reader useless. In this paper we purposed a secure system that provides information about authorized and unauthorized persons. In this system when card brought near to the RFID module it reads the card information and it compare with the data in the program memory and displays authorized or unauthorized entry. The door opens for authorized entry and marked the attendance corresponding to that code id and save in excel sheet format in SD card and after that display it’s all information on the LCD like name and employee code number that link with authorize entry and welcome message with audio greetings by taking their name which is already saved into SD card and for unmatched entry the gate remain closed and alerts the security person through SPEAKERS by playing the separate audio file saying entry is unauthorized.
