If your Sachivalayam fingerprint scanner shows No Device with RD Service, error 1001, or the device is not detecting during Aadhaar authentication, the RD service may be expired, the driver may be missing, or the scanner may be an old L0 model. Check your device model and serial number first. Then renew RD service only from the official device maker or authorised RD service portal. For Aadhaar-based work, use a valid L1 fingerprint device such as Startek FM220U L1, Mantra MFS110 L1, or Morpho/IDEMIA MSO1300 E3 L1.
What is RD service?
RD service means Registered Device service. It allows a fingerprint scanner to work securely for Aadhaar authentication, eKYC, DBT verification, pension services, ration eKYC, and other government services.
If RD service is expired or not installed properly, the Sachivalayam application may not detect the scanner. That is why errors like No Device with RD Service or 1001 usually appear.
Important update about L0 and L1 devices
UIDAI has moved the Aadhaar authentication ecosystem from older L0 fingerprint devices to more secure L1 registered devices. L1 devices provide stronger device-level security and better protection during biometric authentication.
If you are still using an old L0 scanner, it may not work for Aadhaar authentication anymore. For regular Sachivalayam work, use the correct L1 model and keep its RD service active.
Common scanners used for Sachivalayam work
- Startek FM220U L1
- Mantra MFS110 L1
- Morpho / IDEMIA MSO1300 E3 L1
Before paying for renewal, check the model name printed on the device or shown inside the RD service software. Do not renew RD service for the wrong model or wrong serial number.

- Note the serial number exactly as printed.
- You can also open the installed RD service software and check the device information page.
- Use the same serial number while renewing RD service.
How to renew RD service

- Enter the device serial number carefully.
- Choose the RD validity period, usually 1 year or more depending on the provider.
- Pay the renewal fee online.

RD service validity and cost
RD service is usually renewed for a fixed validity period, commonly one year. The renewal fee depends on the device maker, model, validity period, and whether warranty or extra support is included.
Do not rely on old prices shown in WhatsApp messages or YouTube videos. Always confirm the latest fee on the official RD service payment page before paying.
Common RD service errors and fixes
| Error | Possible reason | What to do |
|---|---|---|
| No Device with RD Service | RD service expired, driver missing, or scanner not connected | Renew RD service, install the correct driver, and reconnect the device |
| Error 1001 | RD service validity issue or registration problem | Check RD validity and renew through the official portal |
| Device not detected | USB issue, driver issue, or wrong RD software | Try another USB port, reinstall the driver, and restart the system |
| L0 device not working | Old device model is no longer suitable for Aadhaar authentication | Upgrade to the correct L1 fingerprint scanner |
| Hardware error | Scanner may be damaged or unsupported | Contact the device maker or authorised support centre |
After renewal, install the latest driver
Renewal alone may not fix the issue if the latest RD service driver is not installed. After renewing, download the correct Windows or Android RD software for your exact scanner model. Install it with administrator permission if you are using Windows.
After installation, unplug the scanner, wait a few seconds, reconnect it, and then open the Sachivalayam application. If the device is still not detected, restart the computer and test again.
Safety tips before making payment
- Use only the official device maker or authorised RD service portal.
- Do not pay through random WhatsApp links.
- Check the device model before renewal.
- Enter the serial number carefully because wrong activation may not be refunded.
- Keep the payment receipt and activation message safe.
When should you replace the scanner?
If your device is an old L0 model, physically damaged, not supported by the latest RD service, or repeatedly showing hardware errors, renewal may not help. In that case, replacing it with a compatible L1 device is the better option.
Frequently asked questions
Why does my scanner show No Device with RD Service?
This usually happens when RD service is expired, the correct driver is not installed, or the scanner is not connected properly. Renew RD service, install the latest driver, and reconnect the device.
What does error 1001 mean?
Error 1001 is commonly related to RD service validity or registration. Check the RD service status using your device serial number and renew it if required.
Can I use an L0 fingerprint scanner now?
For Aadhaar authentication work, old L0 scanners are no longer recommended and many models have already been phased out. Use a valid L1 fingerprint scanner for Sachivalayam services.
Where can I find the device serial number?
The serial number is usually printed on the sticker at the back of the scanner. It may also be visible in the RD service software under device information.
Should I renew RD service from any reseller website?
No. Use only the official device maker or authorised RD service portal. Wrong renewal websites can cause payment loss, wrong serial activation, or delayed support.
