Attendence Applicaiton

An application that can be used by employees to record attendance using facial recognition.

Features

The features of the application are,

• Authentication of an employee based on facial recognition and geolocation. The application checks whether the employee is inside the office while recording attendance.
• Registration of employees with face and office geolocation.
• Feature to view attendance recorded by the employee.
• Feature to update the details of employees with certain concerns.

Workflow

The workflow of the application is as follows,

• Employees should register themself from the office as the current location is captured during registration and further attendance can be made only from this location.
• For employees with work-from-home case scenarios, barcode-based authentication is also provided.
• Employees can log in themself with their email and password.
• Employee can scan their face to mark attendance. The work-from-home option should be enabled through the website by the manager and in such cases, the employee can perform a barcode-based login.
• For in-office employees geolocation is also checked during attendance.
• The employee can check in and check out to record attendance.
• The employee can view his attendance based on the month.
• The employee can also change his data at most once through the application.

Database setup

Firebase is being used as a database for this application. The schema is,

• Employee collection with auto-generated id. The document in employee has the following values,

{
  "WorkType": "in-office",
  "address": "",
  "birthDate": "02/28/2023",
  "canEdit": false,
  "firstName": "hari",
  "id": "[email protected]",
  "lastName": "hara sankar",
  "lat": 11.4958421,
  "lon": 77.2761778,
  "password": "12345678"
}

The password must be stored in an encrypted format. This is just shown for reference, but we can use firebase authentication services to manage users.

• A record sub-collection of the employee collection.
• The record sub-collection will have the date of attendance as the document ID.
• The document has the following value,

{
  "checkIn": "04:11",
  "checkInLocation": "BIT-IT Lab, Tamil Nadu, 638401, India",
  "checkOut": "04:13",
  "checkOutLocation": "BIT-IT Lab, Tamil Nadu, 638401, India",
  "date": "March 20,2023 at 4: 13: 00 PM U"
}

The date is stored as a timestamp in firebase.

Also, enable signIn using email in the authentication section of firebase. Register your app with the package name com.bytx.attendanceapp and place the google-services.json file in the /android/app/ folder.
