Mantra MFS110 RD service not working: Mantra-specific fixes

Who this guide is for

This guide is for Mantra's L1 fingerprint scanners — mainly the MFS110, and also the MARC11 and MFS210, which use the same download portal. If your scanner is an MFS100, it is an L0 device and no software fix will bring it back; read our L0 vs L1 explainer. For general steps that apply to every brand, see the RD Service not ready guide.

The steps below come from Mantra's own *MFS110 Registered Device Service manual for Windows*, as republished by the Ministry of Health (MoHFW) in July 2025, and from the Windows error sheet on Mantra's Servico helpdesk site.

Step 1: Install the two files in the right order

Mantra's portal (mantratec.com/Download/User) asks for your name, e-mail, mobile number and an OTP, then gives two separate downloads: the MFS110 driver and the MFS110 RD service.

1. Right-click the driver setup and choose Run as administrator. The manual explains that the driver setup writes to the system32 folder, so it needs administrator rights.
2. Right-click the RD service setup and choose Run as administrator too.
3. After installation, the RD service appears under Control Panel → Administrative Tools → Services.

Step 2: Let the device register

When the RD service detects the scanner, it converts it into a registered device and shows a success message. The manual then asks you to unplug the scanner and plug it in again. From then on, the RD service validates the device with Mantra's management server every time it is connected.

If you see a message that the device is not listed on Mantra's management server, the fix is not on your PC: contact Mantra's Servico team (servico.mantratecapp.com, phone 079-49068000 or 079-69268000, e-mail servico@mantratec.com). The manual says device listing on the management server is done by sending the device's serial number to servico@mantratec.com.

Step 3: Open the network path to Mantra's server

The manual is clear that the RD service must talk to Mantra's management server, and that the PC must be able to reach https://aadhaardevice.com and all its sub-domains. Mantra's Windows error sheet adds detail for error 2100 ("Could not connect to vendor server"):

• check that the PC has a working internet connection;
• if your office network blocks traffic, allow the domain *.aadhaardevice.com on port 443 in your firewall or gateway, inbound and outbound.

If your internet goes through a proxy, use the Config Mantra MFS110 RDService shortcut that the RD service places on the desktop and in All Programs. Enter the proxy details (user name and password only if your proxy needs them), click Test Proxy, and when it says OK, click Save Proxy. Then unplug and replug the scanner so the RD service picks up the new setting.

Step 4: Check the system time zone

The manual has a separate step to configure the system time zone. Open Settings → Time & language → Date & time, set the time zone to (UTC+05:30) Chennai, Kolkata, Mumbai, New Delhi and turn on Set time automatically. Then restart the RD service from services.msc.

Step 5: Test outside your application

The manual lists a Mantra test page — http://rdtest.aadhaardevice.com/ (or the https version if your web application runs on https). It detects every RD service installed on the PC, shows the connected device's information and can capture a fingerprint. If the test page captures but your CSC, AePS or banking application does not, the problem is in the application or browser, not the scanner.

The manual also describes browser settings for applications that call the RD service from a plain-http page. Browser flags change from version to version, so ask your application provider before changing them.

Error codes from Mantra's Servico sheet

• 4003 (System.Net web exception): UIDAI's server timed out while a new device was being registered. Mantra advises confirming UIDAI server availability with Mantra.
• 521 ("operator authorisation failed" after reinstalling on a formatted PC): a newly registered device can take 5 to 24 hours to reflect on all of UIDAI's mirror servers, so register a device one day before you need it.
• 2100: could not connect to the vendor server — see Step 3.

When the subscription has expired

Mantra's MFS110 and MARC11 product pages say a one-year RD service subscription is included and renewal is chargeable (the MFS210 page doesn't state its terms). Renewal is paid on Mantra's Servico payment page against the device's serial number. Our guide on checking RD validity and renewing it covers all three brands.

Never use "fixed" RD services

Files shared on WhatsApp or YouTube that claim to skip renewal or revive an MFS100 are not from Mantra. Use only mantratec.com, which we link from our MFS110 page.
