It is quite difficult to follow up personnel at a workplace with hundreds of staff members. Specifically, the Human Resources unit lists the daily finger readings of the previous day to determine who has arrived.

Isit program every 10 minutes by scanning the staff who read the finger, not detecting the personnel who do not come, sending the SMS and e-mail to the staff supervisor who do not come.

Thus, not a day after the people who do not come at the moment you are notified.
