RD service subscription expired? Check validity and renew (Mantra, Morpho, Startek)

Why a working scanner suddenly stops

An L1 fingerprint scanner is only accepted for Aadhaar authentication while its RD (Registered Device) service is whitelisted on the maker's management server. That whitelisting is sold as a subscription. When it lapses, the scanner can still light up and Windows can still see it, but the RD service refuses to report it as ready. Typical symptoms:

• Morpho: the device "stopped working or is asking for One Time Token" (rdserviceonline.com's own wording), or the message "Your device is blacklisted from the management server".
• Startek: "Subscription Expired" or "Device is blocked" during registration, which Access Computech says only its support can resolve.
• Mantra: a message that the device is not listed on Mantra's management server, which Mantra's manual says needs its Servico team.

Before paying, rule out the free causes: wrong PC date or time zone, no internet, or a proxy blocking the RD service. Our RD Service not ready guide covers those.

Step 1: Read the serial number correctly

Every renewal is tied to the device's serial number, so copy it exactly from the label under the scanner. If the label has worn off, rdserviceonline.com has a Find Device S/No. page for Morpho devices, and Mantra's Servico payment page has a "How to check correct serial number" help link. A typo here can renew someone else's device.

Step 2: Check validity and renew — Morpho (IDEMIA)

1. Open rdserviceonline.com and choose Check validity ("Already have RD service?").
2. Enter up to five device serial numbers. The form rejects serials shorter than 11 digits.
3. The result shows the device status and type, and for whitelisted devices the whitelisting date and expiry date.
4. To renew, use Renew RD Service on the same site, choose the validity years and pay. The cart notes that renewal is done against the credentials you provide.

When we checked on 30 October 2026, the site advertised RD service at ₹375 per device. It also lists the old L0 model as "MSO 1300E3 Public Model (Previously L0)" — check UIDAI's rules for your application before renewing an L0 device.

Step 3: Renew — Mantra (MFS110, MARC11, MFS210)

Mantra's MFS110 and MARC11 product pages say a one-year RD service subscription is included; after that, renewal is paid on Servico, Mantra's official service platform (servico.mantratecapp.com → Make Payment).

1. Choose RD Service as the payment option.
2. Enter company or name, mobile, e-mail and GST number if you have one.
3. Select L1 Device, add the serial number(s) and pick the plan.
4. Pay and save the payment ID.

On 30 October 2026, the page listed a one-year RD subscription at ₹200 (shown against an MRP of ₹600), with higher-priced options that add warranty; GST is added at checkout. For anything the page can't handle, Mantra's manual gives servico@mantratec.com and 079-49068000 / 079-69268000.

Step 4: Renew — Startek (Access Computech)

1. Open ACPL's Extend subscription page (acpl.in.net → Extend subscription).
2. Paste your serial numbers — up to 100 per order, each 6 to 32 letters or digits. The page checks each one and lists eligible devices separately from those already subscribed, blocked or on a lifetime plan.
3. All devices in one order must be the same type. L0 devices can't be renewed there.
4. Choose a plan and pay online (Razorpay) or by bank transfer.

Rates shown on 30 October 2026, per device: one year ₹200 + ₹36 GST = ₹236; device lifetime ₹600 + ₹108 GST = ₹708; optional extended (online/remote) support ₹300 + ₹54 GST.

Step 5: After renewing

1. Restart the RD service in services.msc (or restart the PC).
2. Unplug the scanner and plug it into a rear USB port again so it re-registers.
3. Test capture in the maker's tool before you go back to your CSC, AePS or banking application.

If it still isn't ready a day later, contact the maker with your payment ID and serial number: Morpho 0806-936-8000, Access Computech +91-265-3114090 or support@acpl.ind.in, Mantra servico@mantratec.com.

Avoid renewal scams

Pay only on the maker's own site — rdserviceonline.com, servico.mantratecapp.com or acpl.in.net. "Lifetime activation keys" sold on WhatsApp or marketplaces are not something any of these makers documents, and patched RD services can carry malware.
