If the system calculates payroll, add a field for THR. In the salary.php file, insert:
$thr = ($month == 'March' || $month == 'April') ? ($base_salary * 1) : 0;
Ari was staring at a spreadsheet. Not just any spreadsheet—the attendance spreadsheet. It was a shared Google Sheet with 43 employees, 14 conditional formatting rules, and three different timezone columns.
Every morning, he manually checked who had “checked in” by typing IN in Column C. But yesterday, someone had accidentally deleted rows 12 through 28.
His co-founder, Lina, walked in. “Three people haven’t logged their sick leave. And HR is asking for last month’s attendance report. Also, we have zero budget for attendance software.” absensi karyawan github free

Most free systems implement JWT (JSON Web Tokens) or session-based auth. Few implement two-factor authentication (2FA). For Indonesia's absensi context, many repositories add NIK (National ID) validation.
Indonesian companies often have a grace period (e.g., 15 menit). The script should calculate late_minutes = check_in_time - shift_start_time - grace_period.

No, if:
Open the AttendanceController.php file. Find the checkLate function. Add logic:
if ($minutesLate > 15)
$deduction = ($minutesLate / 60) * $hourlyRate;
$attendance->fine = $deduction;
