Worldlink出勤系統

The "Attendance System" is a highly efficient mobile attendance and leave management application tailored for WorldLinker enterprise employees. This application combines robust security encryption technology with an intuitive user interface, aiming to help employees easily complete daily attendance tracking and allow managers to conveniently review leave requests, comprehensively improving enterprise administrative efficiency.

【Core Function Highlights】

1. Mobile Location-Based Attendance Tracking
Supports precise GPS geolocation verification. After arriving at the designated attendance area within the company, employees can quickly complete "clocking in" or "clocking out" with a single tap, avoiding the queuing and cumbersome process of traditional time clocks.

2. High-Strength Security Protection and Integrity Verification
We employ the highest level of security technology to protect your attendance records and prevent forgery:

- End-to-End Encryption: Each attendance request is encrypted during transmission via ECDH key negotiation (secp256r1) and the AES-GCM high-strength algorithm.

- Hardware-level protection: Supports hardware security chips (Android KeyStore TEE/SE) to ensure that the key cannot be exported or cracked.

- System integrity verification: Integrates Google Play Integrity verification to effectively prevent emulator attendance, virtual GPS location, and third-party tampering.

3. Self-service leave application and quota inquiry: Employees can submit applications for various types of leave (such as special leave, sick leave, personal leave, menstrual leave, marriage leave, and bereavement leave) at any time within the app. The main screen will display each employee's "used quota" and "remaining quota" in real time, providing data transparency and facilitating personal leave planning.

4. Historical record tracking: Provides comprehensive tracking of "recent attendance history" and "leave records," allowing users to review daily attendance times and leave application review status (e.g., pending review, approved, withdrawn).

5. Mobile Approval Management (Manager-Only)
Managers with administrative privileges can receive leave applications directly on their mobile devices and approve or reject them with a single click, significantly shortening the approval process and achieving efficient paperless management.

【Usage Notes】
- This application is for authorized employees of WorldLinker Corp. only.

- First-time login requires authentication using your company-configured email address.

- To ensure the accuracy and security of attendance tracking, location services and internet connectivity must be enabled on your device during attendance tracking, and it is recommended to agree to the authorization of relevant security credentials.
