Touch Time app can help you with your HRM related needs. Like marking office attendance and time tracking of back-office staff with fingerprint authentication (External fingerprint scanners) or GPS enabled location-based attendance for an outdoor team.
While we built TouchTime Attendance for school teachers initially, the app works perfectly for tracking attendance online for any class, group, or gathering! There are thousands of others using it to track:
Yoga class attendance
Church groups
Martial arts classes
Employee attendance
The list goes on and on!
