Fingerprint System

📖 Fingerprint Scanner — General Logic

This is the welcome screen of the police fingerprint scanner device. It’s the first interface officers see when activating the tool, and it serves as the entry point for starting new scans or reviewing old results.


🔹 Main Features

  • Welcome Screen

    • Displays a police badge and a short description.

    • Designed to simulate the real-life police fingerprint scanners.

  • New Scan Button

    • Starts the fingerprint scanning process.

    • When pressed, the system prompts the suspect to place their finger on the scanner.

    • Once scanned, the system runs the fingerprint against the database and shows results (ID, name, etc.).

  • History Button

    • Opens the list of previously recorded scans.

    • Allows officers to review past fingerprint matches and data for ongoing investigations.
