Fingerprint Smart Lock for OEM Supply: TD-F2-B
The TD-F2-B is a fingerprint smart lock built for private-label and project buyers who need more than one way through the door. Fingerprint is the everyday credential. Face, palm vein, IC card, PIN, the Tuya app and a mechanical key cover the users and situations that fingerprint alone cannot.
The TD-F2-B is in stock for standard supply. Private-label programmes start at 500 units. Confirm the configuration and destination documents before quotation.
Fingerprint first, with documented fallback routes.
Fingerprint carries daily entry. The other credentials cover visitors, staff, worn fingerprints and power loss.
Where Fingerprint Fits in a Multi-Credential Lock
Fingerprint should carry most daily entries. The other credentials cover the people and moments where a finger read is slow, unreliable or not possible. Plan the credential mix around who uses the door, not around how many methods the lock lists.
| Credential | Typical user | Why it is there | Confirm on the sample |
|---|---|---|---|
| Fingerprint (semiconductor sensor) | Residents, staff | Fast daily entry, nothing to carry | Enrolment time, wet or dry finger reads |
| Face recognition | Frequent users, hands full | Hands-free entry | Lighting at the door, 50-set limit |
| Palm vein | Users with worn fingerprints | Alternative biometric | Read position and speed |
| IC card | Cleaners, contractors | Easy to issue and revoke | Card type supplied by the project |
| PIN and temporary PIN | Visitors, deliveries | Time-limited access | Who issues and expires codes |
| Tuya Smart app | Owner, property manager | Remote access and user management | Account roles on the target network |
| Mechanical key (Grade C cylinder) | Emergency only | Works with no power | Key control and spare-key policy |
The lock also supports combination verification, so a door can require two credentials, such as fingerprint plus card. If you are still choosing between a face-first and a fingerprint-first lock, compare the two approaches in face recognition vs fingerprint smart lock.

Door Fit and Installation Checks
Check the door before the electronics. A good fingerprint read does not help if the lock body does not suit the mortise, handing or clearance. Check these points on one representative door before you approve the sample:
- Panel footprint. The front panel is 425 × 70 mm and the rear panel 413 × 76 × 73 mm. Check them against the existing trim, glass and door edge.
- Lock body and handing. Confirm the mortise type, backset and opening direction used in the target market.
- Door thickness and material. Record the thickness range and door materials the project needs, including any metal or fire-rated doors, and confirm them on the sample.
- Cylinder. The emergency cylinder is Grade C. Check whether the buyer or local insurer requires a different cylinder grade.
- Exposure. The operating range is −25 °C to +70 °C. Doors facing direct sun or rain need a site review before specification.
The full measurement routine is in the smart lock door fit checklist. For European door types, see Europe smart lock door compatibility.
Power, Battery and Emergency Access
The TD-F2-B runs on a 4,200 mAh lithium battery. The data sheet lists a static current of up to 120 μA and a dynamic current of up to 4 A. Real runtime depends on daily entries, Wi-Fi activity, camera and screen settings, and temperature, so we do not quote a fixed number of months. Measure it on the sample with your expected usage.
If the battery runs flat, there are two ways in:
- Connect a 5 V power source to the USB Type-C emergency port beside the keyhole on the front panel, then use a stored credential.
- Use the mechanical key in the Grade C cylinder.
Agree the low-battery alert behaviour and the charging instructions in the user manual before launch. Common causes of fast drain are covered in why smart lock batteries drain fast.
Market Documents by Destination
Documents are confirmed by exact model, hardware revision, radio module and destination. Certificate copies and test reports are available on request. Ask for the certificate number, issuing body and covered model list. A file issued for another lock or radio version does not transfer.

Fingerprint Smart Lock OEM Options
Standard supply starts at 200 units, OEM and private label at 500 units, and ODM development at 1,000 units. Final terms are confirmed in the written quotation for the selected configuration.
OEM scope for this model can include:
- logo application on the panel
- custom retail or project packaging
- white-label app configuration
- housing colour
- selected firmware requirements and manual language
The usual route has four steps. Share your brief. Approve one fit sample. Freeze the configuration and documents. Then release the production order. Lead time is set once the configuration is fixed. For the full programme, see the smart lock OEM programme.
What Is in the Box
Each TD-F2-B ships with the parts needed for a standard installation, as listed on the data sheet:
- front panel and back panel
- lock cylinder and keys
- lithium battery
- IC cards
- square bar, anti-lock toggle piece and spring
- M5 fixing screws ×2, M4 set screws ×2 and sleeves ×2
- silicone plug
- user manual
Check the square bar length and fixing screws against the door thickness on the fit sample. For private-label orders, confirm the manual language and packaging marks at the same time.
Sample Acceptance Before Volume Orders
A sample is useful only if it is tested the way the lock will be used. Run these five checks and keep the results with the order file:
- Every credential. Enrol and test fingerprint, face, palm vein, card, PIN, temporary PIN, app and key. Include combination verification if the project uses it.
- Power events. Run the lock to low battery, confirm the alert, open it through the Type-C port, then recharge and re-test.
- User lifecycle. Add, change and delete a fingerprint and a face set. Record who on the buyer side owns enrolment and deletion after handover.
- App and network. Pair the lock with the Tuya app on the target Wi-Fi network. Invite users with the roles the project needs, and check what happens when the network drops.
- Labels and paperwork. Check the rating label, manual language, declaration of conformity and packaging marks against the destination.
Approve the volume order only after every exception from these checks is closed.

TD-F2-B Fingerprint Smart Lock: Common B2B Questions
A semiconductor (capacitive) sensor reads the electrical difference between ridges and valleys. An optical sensor reads an image. Spoof resistance and wet or dry performance depend on the exact sensor, firmware and test conditions, so ask for model evidence before you specify.
Read performance varies with finger condition and the user group. Test with a sample of your actual users, including older users and staff with worn fingerprints. Palm vein, card and PIN are available when a finger read fails.
3 administrator sets, 297 general-user sets shared across fingerprint, password and card, and 50 facial-recognition sets. Palm-vein capacity is not listed on the data sheet. Confirm the enrolment mix and app workflow on the sample.
Power the lock through the 5 V USB Type-C port and use a stored credential, or open it with the mechanical key. Runtime and the low-battery threshold depend on the configuration and are confirmed on the sample.
CE LVD, CE RED, RoHS 3, UKCA and FCC Part 15 are listed for this model, and SASO documents are reviewed by project. Copies and test reports are available on request. Tell us your destination and any standard your tender names before quotation.
The published configuration uses Wi-Fi and the Tuya Smart app. Do not assume Wiegand, OSDP or another access-control interface. Name the controller, firmware and workflow so the connection can be reviewed before supply.
Confirm where biometric templates and access logs are stored, how deletion and export work, and who operates the data. Workplace projects in Europe should complete their own DPIA and legal-basis review before deployment. Background: GDPR for access control in Europe.
