Frequently Asked Questions — Next Biometrics RD Service FAQ & Troubleshooting
Next Biometrics RD Service typically runs on ports between 11100 and 11105 on 127.0.0.1 (localhost). If port 11100 is in use by another driver, it shifts dynamically to the next free port in that range.
Unlike standard optical scanners that can struggle with harsh sunlight, skin oil, or wet hands, Next Biometrics patented Active Thermal technology measures temperature transfer from the skin ridges, ensuring consistent biometric capture even on worn or dry fingerprints.
Click '1. Run Initialization & Port Scan'. Once the device is detected on localhost, click 'Serial Number'. The tool queries the device's internal XML parameters and displays the hardware serial number in the modal and terminal.
Error 720 or NOT READY means USB communication was lost or locked by another app. Disconnect the USB cable, wait 5 seconds, reconnect directly to a high-power USB 2.0/3.0 port, restart "Next Biometrics RD Service" in services.msc, and re-run Initialization.
Yes! Install the official Next Biometrics RD Service application from the Google Play Store, connect your Oyster scanner with an OTG cable, and run this test page in Chrome on Android.
