Businesses, schools, and places that operate outdoors must keep track of attendance.  Conventional techniques, such as RFID-based systems, biometric scanners, and manual roll calls, may be burdensome for administrators, inefficient, and open to fraud, such proxy attendance.  Geolocation-based attendance monitoring has become a realistic option for assuring accuracy, transparency, and automation owing to the swift development of mobile technology and the ubiquitous availability of Global Positioning System (GPS) services.  This paper presents a geolocation-based methodology for attendance management that utilises cloud computing, geofencing, and mobile apps to verify user presence in specified locations before documenting attendance.
