fingerprint r503 finger print

Fingerprint Sensor with Rugged Panel Mount and Bi-Color LED Ring (R503)

LE 750.00

Add biometrics to your project. This all-in-one optical fingerprint sensor will make adding fingerprint detection and verification very simple.

This fingerprint module is powered by DSP chip that does the image rendering, calculation, feature-finding, and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos and search. Up to 200 fingerprints can be stored in the onboard FLASH memory.


You can use dust and rain resistant high quality and heavy duty Zink Alloy enclosure for protecting the fingerprint module and outdoor applications .
