GROW R503 Capacitive Fingerprint Module

The GROW R503 is a capacitive fingerprint module equipped with an integrated image collecting and algorithm chip. This allows it to securely store up to 200 fingerprints, as images of fingerprints never leave the module. Furthermore, it boasts a high recognition rate regardless of conditions—it effectively identifies fingerprints whether the finger is dry or wet, and regardless of the texture of the finger, whether it's fine or marked.
