Access control decides who can open a door, and when. This collection currently lists two ZKTeco biometric terminals, the ZKTeco K40 and the ZKTeco F18. ZKTeco is a well-known maker of biometric and time-attendance equipment, and retailer listings describe both models as fingerprint terminals used for door control and staff attendance.
How a fingerprint terminal works
Each user is enrolled on the terminal, which stores a fingerprint template. When the finger is presented, the device compares it to the stored templates and, on a match, switches a relay that releases the lock. There is no key to lose or copy, and each entry is logged with a time, which is why the same terminals double as attendance clocks. Retailer listings give the F18 a 2.4-inch colour screen with TCP/IP and RS232/RS485 communication, and the K40 a 2.8-inch screen with TCP/IP and a USB port. Listed fingerprint capacities are in the low thousands and vary between sellers, so confirm the figure for your unit.
Choosing the lock
The terminal does not hold the door shut; an electric lock does. Pick the lock for the door:
| Lock | Behaviour | Considerations |
|---|---|---|
| Electric strike | Usually configurable as fail-secure or fail-safe; keeps the mechanical lock | Secures one side of the door and needs precise fitting |
| Magnetic lock | Fail-safe: releases when power is cut | Holds both sides, has no mechanical backup, needs a request-to-exit device |
Always plan an exit route and follow fire and building rules for your premises.
What to look for
- Standalone or networked: a standalone terminal manages users on the device; a networked one reports to software on a PC.
- User and record capacity: enough fingerprint and log memory for your staff.
- Power: the terminals use a 12V DC supply (the F18 is listed at 3A), so size a supply for the terminal and the lock together. See 12V power supplies.
- Backup power: a battery or UPS keeps doors working during outages.
- Enrolment quality: dry, worn or damaged fingers can be hard to read, so enrol more than one finger.
Typical uses in Kenya
- Staff entrances, server rooms and stock rooms.
- Pharmacies, cash offices and laboratories.
- Schools, factories and gated estates, together with a video intercom for visitors.
Frequently asked questions
Is fingerprint access secure?
It removes keys and shared PIN codes, common weak points. Quality depends on the device and installation.
Can it record attendance?
These terminals are sold for time attendance as well as access. Confirm features on the model you choose.
What lock do I need?
That depends on the door type and fire-exit rules. Ask us if you are unsure.
