7842358459 RF-ID BASED SCHOOL / COLLEGE ATTENDANCE SYSTEM & PARENTS ALERT USING
GSM MODEMABSTRACT: Radio Frequency Identification (RFID) system is an identification system
thatuses radio waves to retrieve data from a device called a tag or transponder. RFID is anarea of
automatic identification that has quietly been gaining momentum in recent yearsand is now being seen as
a radical means of enhancing data handling processes,complimentary in many ways to other data capture
technologies such bar coding. Theobject of any RFID system is to carry data in suitable transponders,
generally known astags, and to retrieve data, by machine-readable means, at a suitable time and place
tosatisfy particular application needs. Data within a tag may provide identification for anitem in
manufacture, goods in transit, a location, and the identity of a vehicle, an animalor individual. An RFID
reader/writer contains a scanning antenna and a transceiver. It uses thescanning antenna to send out
radio frequency signals in a relative short range. The radiofrequency sent out is used to communicate and
power tags (also known as transponders)that are within range, which will then transmit the data on the tag
back to the reader. Thescanning antenna then picks up the information sent out by the tag. The data is
theninterpreted and decoded by the transceiver. Our RFID based Attendance MonitoringSystem is a
micro controller based compact unit to monitor the employee’s attendancethrough proximity access ID
cards (RFID - Radio Frequency Identification). This cardcan be designed to hold all employee details
including Name of the Company andAddress, Hologram, Employee name, ID number, Photo Images,
position, Department,Qualification, Date Of Joining, and more. Attendance monitoring is very
simple.www.svsembedded.com SVSEMBEDDED svsembedded@gmail.com, CONTACT: 9491535690,

7842358459 This System assigns a unique card number for each employee. An employeeplaces the
RFID card within 5cm distance from the RFID Reader. The RFID Readerwrites down the time, date and
type of departure/arrival in a NVRAM or EEPROM. Thetype of arrival/departure is indicated on the LCD
display. The display also indicates thecurrent time. After recording the attendance data this information
can be downloaded intoa supervisory PC through a RS-232 serial port.The Interface software is
responsible for attendance record data processing and itproduces attendance reports in required format.
Attendance processing (Interface)software can also be integrated with the payroll software for salary
calculation andemployee tracking. Manual entry is also possible.METHODOLOGY: Attendance
monitoring is very simple. This System assigns a unique card numberfor each Student. An Student places
the RFID card in the RFID card Reader. The RFIDcard Reader reads down the Student details. The
details will be indicated on the LCDdisplay and send through GSM modem to parents The display also
indicates the currenttime. The Interface software is responsible to control the door depends upon the data
baseverification. The holding capacity (number of Student s) of the reader is depends uponthe memory
interfacing, i.e., whether interfacing with PC or separate RAM units. This project is implemented using
RFID card reader/writer, ARM7LPC2148micro-controller, driver unit for door/locker control and LCD
display is used todisplay the tag details, buzzer to indicate confirmation of verification.Key attributes of
RFID are that, unlike barcodes, RFID tags can be read: • Without a line of sight from the reader; • In any
orientation to the reader;www.svsembedded.com SVSEMBEDDED svsembedded@gmail.com,
