HP 825535-001 biometric fingerprint reader is an integrated module for fingerprint authentication in compatible HP point-of-sale and all-in-one systems. It provides a direct way for a supported system to identify a user by fingerprint.
The reader captures fingerprint images at 508 DPI using capacitive array technology. Its specified 5-pin interface connects the module with its host system. The part is listed for HP Engage One and RP9 G1 Retail System models 9118, 9115, 9018 and 9015, making it relevant when servicing or configuring those systems.
This module is intended for system integration rather than general standalone use. Its compact role is focused: fingerprint input for compatible HP equipment.
