A top-tier feature for a free employee attendance system on GitHub is GPS-Based Geofencing with Anti-Fake GPS Detection

While basic attendance apps simply log time, adding geofencing ensures employees are physically at the office or a designated site before they can "clock in". This addresses common issues like "attendance fraud" where employees might ask colleagues to sign in for them. Key Sub-Features to Implement: Geofencing Radius

: Restrict attendance actions to a specific radius (e.g., 50 meters) around the office coordinates. Anti-Fake GPS Security

: Implement checks to detect and block mock location apps or VPNs that attempt to spoof GPS coordinates. Selfie/Face Verification

: Require a real-time photo during the clock-in process to confirm the employee's identity, preventing "buddy punching". Offline Syncing

: Allow employees to clock in if they have a weak signal, then sync the data (with original timestamps) once they are back online. Recommended GitHub Repositories for Inspiration: : An open-source HRIS system featuring GPS Geofencing Anti-Fake GPS Laravel-Presensi

3. Reporting & Export

A free system is useless if you can't extract data. Ensure the repo includes an "Export to PDF/Excel" button for monthly recap (Rekap Bulanan).

Step 4.3: The Backend Script (API)

We need a script to allow the website to talk to the Sheet.

1. In Google Sheets, go to Extensions > Apps Script.
2. Delete any code in the Code.gs file and paste the following:

// Google Apps Script Code
// 1. Handle GET requests (Verify Employee)
function doGet(e) 
var op = e.parameter.op;
if (op === 'check') 
return checkEmployee(e.parameter.id);
return ContentService.createTextOutput("Invalid Operation");

// 2. Handle POST requests (Log Attendance)
function doPost(e) 
var data = JSON.parse(e.postData.contents);
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Logs");
sheet.appendRow([
new Date(),
data.id,
data.name,
data.status,
data.lat,
data.lng,
data.accuracy
]);
return ContentService.createTextOutput(JSON.stringify(result: 'success'))
.setMimeType(ContentService.MimeType.JSON);

// Helper function to check if employee exists
function checkEmployee(id) 
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Employees");
var data = sheet.getDataRange().getValues();
for (var i = 1; i < data.length; i++) 
if (data[i][0] == id) 
return ContentService.createTextOutput(JSON.stringify(
status: 'found',
name: data[i][1],
position: data[i][2]
)).setMimeType(ContentService.MimeType.JSON);

return ContentService.createTextOutput(JSON.stringify(status: 'not_found'))
.setMimeType(ContentService.MimeType.JSON);
 In Google Sheets, go to  Extensions &gt; Apps Script

3. Click Deploy > New Deployment.
4. Select type: Web App.
5. Execute as: Me. Who has access: Anyone.
6. Click Deploy. Copy the Web App URL (looks like https://script.google.com/macros/s/XXXX/exec). Save this URL, you will need it for the frontend.

5.1 Authentication & Security

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.

Step 4.2: Define Columns

In the Employees sheet:

• A1: Employee ID
• B1: Name
• C1: Position (Fill rows A2, B2, C2 with sample employee data, e.g., E001, John Doe, Staff)

In the Logs sheet:

• A1: Timestamp
• B1: Employee ID
• C1: Name
• D1: Status (Check-In/Check-Out)
• E1: Latitude
• F1: Longitude
• G1: Accuracy (meters)

5.3 Reporting & Analytics

Free projects typically use:

• Chart.js or ECharts for attendance trends.
• Export to Excel via PHPExcel or Laravel Excel.
• Monthly recap showing present, absent, late, and overtime.

Case Study: Toko Sembako "Murah Jaya" Implements Free GitHub Absensi

Background: 12 employees, no computers, only smartphones. Budget: Rp 0.

Solution: The owner searched "absensi karyawan github free", found a Telegram Bot-based attendance system (Python + Telebot).

Implementation:

• Hosted on Render.com free tier.
• Employees send a photo to a Telegram bot with /checkin.
• Bot stores GPS location from Telegram metadata.
• Every Friday, the bot sends an Excel file to the owner's WhatsApp (via Telegram bridge).

Result: Saved Rp 2.4 million per year compared to a paid attendance app. Reduced "titip absen" by 90% because of mandatory location photo.
