R558S Capacitive Fingerprint Acquisition Module Pack of 2 Overview A capacitive fingerprint acquisition module designed for integration into access control and security equipment. Supplied as two identical R558S modules for flexible deployment and testing. The module captures fingerprint patterns and provides the raw data needed for fingerprint recognition systems. Key benefits Reliable fingerprint capture for access control applications: the capacitive sensing method captures detailed fingerprint ridge information to support accurate recognition algorithms. Ready for system integration: compact modules that simplify adding fingerprint input to access control panels, standalone terminals, or embedded devices. Reduces administrative overhead: replaces keys and cards with biometric authentication to streamline user management and reduce lost credential issues. Versatile deployment: two modules included to speed development, allow parallel testing, or cover multiple entry points. What it does Acquires fingerprint images using a capacitive sensing element. Outputs fingerprint data for use by recognition software or access controllers. Serves as the biometric input component in security systems and authentication devices. Compatibility and integration Intended for incorporation into access control systems, time and attendance terminals, secure cabinets, lockers, kiosks, and embedded security projects. Designed to work with common fingerprint recognition workflows and controller architectures. Integration requires appropriate signal and data interface matching to the host system. Form factor and build Compact modules suitable for mounting inside panels, enclosures, or terminals where space is limited. Built for installation into security equipment and embedded devices; mounting and cabling depend on the host design. Practical use scenarios Door access control: integrate into a controlled entry panel to allow authorized personnel to unlock doors with a fingerprint. Time and attendance terminal: add biometric input to record staff checkin and checkout without cards or PINs. Secure storage: install in safes, cabinets, or equipment racks to restrict access to authorized users. Why choose this module Includes two identical R558S modules to support rapid prototyping and multiple access points. Focused on providing a dependable fingerprint acquisition component for security and access control projects. Neutral, integrationfriendly design that can be adapted to a variety of system architectures. Note Integration requires matching the module outputs and power to the host controller and applying appropriate fingerprint processing software or firmware for recognition and access decision making.
