Quick answer: Yes — ZKTeco BioTime offers a genuine free license, but it’s limited (commonly 2 devices and a capped employee count, varying by region) and covers the software only, not the server, database, or maintenance it needs to run.
This guide breaks down exactly what’s free, how BioTime has evolved through its version history, and how it compares to BioCloud and eTOP’s TimeTOP Cloud — so you can pick the right time and attendance software for your business size and budget.
ZKTeco BioTime Free License: What's Actually Included
ZKTeco bundles a free base-tier software license with the purchase of authorized biometric terminals that support ADMS (Automatic Data Master Server) push communication.
Free tier allocation:
- 2 connected devices
- Up to 2,000 personnel (some regional distributors cap this lower — as few as 120 users — so confirm your exact allocation with your local ZKTeco partner)
- 1 mobile app license
- 10-year license validity from activation
What triggers an upgrade: Adding a 3rd device, opening a new branch, or exceeding your personnel cap deactivates the free tier — at that point, a paid commercial license block is required to keep scaling.
What “free” does not include:
- A Windows Server machine to host the software (BioTime supports Windows Server 2008–2022 and Windows 8–11, 64-bit)
- A database engine — BioTime requires PostgreSQL, MS SQL Server, MySQL, or Oracle
- Static IP and SSL setup for remote/mobile access
- Ongoing power, cooling, backup, and IT maintenance
the “free of cost” label refers to the software license only. It’s a genuine cost saving on small deployments, but it is not a zero-infrastructure, zero-maintenance solution.

Factual software logs reveal a clear evolutionary path: ZKTeco is steadily moving away from free, self-hosted architectures toward cloud-hosted, subscription models.

Which One Should You Choose?
Both device lines have shifted toward unified server architectures, abandoning isolated local data storage:
- Choose ZKTeco BioTime (free tier) if you run a single small office with 2 or fewer devices and a limited headcount, already have ZKTeco terminals, and have IT staff able to manage a Windows Server + database deployment.
- Choose a ZKTeco-ecosystem cloud/mobile add-on like BioCloud if you’re already invested in ZKTeco hardware and want mobile geofencing, AutoPunch, and HR self-service layered on top — while understanding you’ll still need to host and maintain the underlying server and database.
- Choose TimeTOP Cloud if you want a centralized, cloud-hosted platform built for multi-location businesses, multi-modal biometric support (not limited to one hardware brand), and offline-to-online sync for field or remote teams — with 24/7 support from a single regional provider.
