Optical fingerprint reader, equipped with high-speed DSP processor, high performance recognition algorithm, Flash memory, UART interface (TTL logical level) for direct connection to microcontrollers or PC through USB-to-serial adapter (MAX232). The user can store fingerprint data (maximum 250) in the form and can configure 1: 1 or 1: N mode to identify people.

Particularly suitable for access control, relay activation, automatic door opening, etc
