Palm Print Scanners

Image
Palm print scanners are biometric devices that capture and analyze the unique patterns and features on the palm of a person's hand for identification and authentication. How they work: Image Capture: The user places their palm on the scanner's surface Image Processing: The scanner captures an image of the palm, focusing on unique features like lines, wrinkles, and creases. 3 Feature Extraction: The system extracts key features from the captured image Comparison: The extracted features are compared to a previously stored template of the individual's palm print. 5 Authentication: If the palm print matches the stored template, the system authenticates the individual's identity. Key Features of Palm Print Scanners: High Accuracy: Palm prints offer a large surface area with many unique features, leading to high accuracy in identification Difficult to Spoof: Palm prints are more difficult to forge compared to fingerprints. Versatility: Can be used for various...
