Many organizations, especially those belonging to the construction or manufacturing sectors, have branches at remote locations. Installing biometric attendance marking devices often becomes difficult at such sites. This only adds to the inconvenience of employees as well as the supervising personnel for proper attendance management. Advancement of technology has allowed supervisors to solve this problem with ease. Battery backup units used with the biometric devices allow employees to mark attendance right from where they are, instead of having to go to the office, which may be at a great distance.
