Automation attendance systems approaches: a practicalreview

Abstract

Accounting for people is the first step for every manpower-based organization in today’s world. Hence, it takes asignificant amount of energy and value in the form of money from respective organizations for both implementinga suitable system for manpower management as well as maintaining that same system. Although this amount ofexpenditure for big organizations is near to nothing and rather just a formality, it does not hold as much truth forsmall organizations, such as schools, colleges, and even universities, to a certain degree. This is the first point.The second point for discussion is that much work has been done to solve this issue. Various technologies, likebiometrics, RFID, Bluetooth, GPS, and QR Code, have been used to tackle the issues of attendance collection.This study paves the path for researchers by reviewing practical methods and technologies used for existingattendance systems
