Quick answer: Choose ZKBio Zlink if you want a simple cloud system with no server. Choose ZKBio Time (BioTime) if attendance and shift reports are your main need. Both Zlink and ZKBio Time can link multiple branches in one system. Choose ZKBio CVAccess for a small door access system of up to 25 doors. Choose ZKBio CVSecurity for larger sites with many doors, turnstiles, visitors or car park control.
Buying the right terminal is only half the job. The software decides how you see attendance, manage doors and pull reports. This guide explains the four main ZKTeco software options in plain terms, and which terminals each one works with.

How to choose: 3 questions



1. Do you want to run a computer or server?
If not, ZKBio Zlink is the answer. Everything runs in the cloud, and managers check attendance and doors from a browser or phone. ZKBio Time, CVAccess and CVSecurity are installed on your own PC or server, so your data stays in your office.
2. Is attendance or security your main concern?
If HR needs shift rosters, overtime and attendance reports across one or many branches, ZKBio Time is built for that. If the priority is controlling who opens which door, choose CVAccess for a small site or CVSecurity for a large one.
3. How big is the site?
Up to 25 doors fits CVAccess. Beyond that, or when you add turnstiles, visitor kiosks, car park barriers or lifts, CVSecurity handles it on one platform.
