Frequently Asked Questions (FAQs) - R503 Fingerprint Module
What is a capacitive fingerprint scanner?
A capacitive fingerprint sensor detects fingerprints by measuring the differences in electrical charge across the ridges and valleys of a finger. This technology provides high security and fast recognition compared to optical fingerprint scanners.
Where is the R503 Fingerprint Sensor Module used?
The R503 module is used in access control systems, biometric authentication, security safes, attendance tracking, laptops, and IoT security devices.
How does the R503 fingerprint sensor work?
The sensor captures a fingerprint image, extracts unique features, and converts them into a digital fingerprint template using advanced pattern-matching algorithms.
What is the difference between optical and capacitive fingerprint sensors?
• Optical Sensors: Capture images using light reflection and analyze the fingerprint pattern.
• Capacitive Sensors (like R503): Measure the electrical properties of fingerprint ridges, making them more secure and resistant to spoofing.
