RFID School Attendance System

Radio Frequency Identification (RFID) is the wireless non-contact use of radio frequency waves to transfer data. Tagging items with RFID tags allows users to automatically and uniquely identify and track inventory and assets. RFID takes auto-ID technology to the next level by allowing tags to be read without line of sight and, depending on the type of RFID, having a read range between a few centimeters to 20+ meters. RFID has come a long way from its first application of identifying airplanes as friend or foe in World War II. Not only does the technology continues to improve year over year, but the cost of implementing and using an RFID system continues to decrease, making RFID more cost-effective and efficient. The RFID reader sense the signals of the RFID tag within 10 cm of range.The reader sends out a power pulse to the antenna. The system has two antenna, which of these, one situated on the tag and other on the reader. The attendance of the students is maintained and their status is updated to the parents via GSM. GSM is used to send SMS to their parents.
