Add fingerprint enrollment, 1:N matching, RGB LED control, template management, on-chip RNG sampling, and raw image capture to any Arduino or ESP32 project in minutes. Also supports AS608, R307, and all EF-01-compatible fingerprint sensor modules. --- ▶ Try It Now — Nothing to Install Open the Web Tester Wire the sensor to a USB-serial adapter, open the link, click Connect . Enroll fingerprints, run 1:N matching, drive the LED and manage templates straight from the browser over the Web Serial API — no download, no firmware, no Python. Chromium-only — Chrome, Edge, Opera, Arc. Firefox and Safari do not implement Web Serial; use the Python desktop tester there. Beyond matching the Python tester feature for feature, it adds a capability probe — it asks your module which optional opcodes it actually implements and shows the result, so an unusual variant explains itself instead of surfacing as a confusing confirm code — plus a way to sample the module's on-chip random number generator and capture the raw fingerprint image with a live width/height/bit-depth explorer, since the module reports neither its own sensor resolution nor its pixel packing.
