Access control features.
A biometric gate only opens for the person it recognises, so a lent card or a shared PIN can't get anyone else through. NCheck adds that check to the gates and turnstiles you already have: a camera or scanner beside the gate identifies the person, and NCheck sends the signal that opens it.
Every opening is logged against a named person, and the same check can record attendance, so the gate and the timesheet don't need separate systems.
One event, two records
A verified entry both opens the door and stamps attendance, with no duplicate systems.
MQTT · HTTP · Bluetooth
Standard protocols talk to relays, controllers and smart locks you already have.
Zones & policies
Per-door authorisation lists, schedules and two-person rules.
Tailgating visibility
Unverified second entries raise alerts in the event stream.
From Standard
Access control is included from the Standard plan, at €1.50 per employee per month.
How a biometric gate works with NCheck.
The person is identified at the gate
A tablet, IP camera or supported scanner mounted beside the gate reads their face, fingerprint or iris. Face matching takes under a second, so a turnstile doesn't build a queue.
NCheck checks the rules
Access schedules and locations decide who may pass through which gate and when, and anyone not authorised for that gate at that time finds it stays shut. Access control and liveness detection both come with Standard and Premium, so a photo held up to the camera won't open the gate.
The gate opens
A successful match triggers the lock, turnstile or barrier over relay, Wiegand, HTTP or MQTT.
The entry is logged
Each opening is recorded with the person, the gate and the time, on the same record as their attendance.
There's more on how biometric access control works over on the blog.
Gates, turnstiles and barriers NCheck can open.
NCheck sends the open signal to the gate hardware already in place, so existing turnstiles and barriers can usually stay.
| Gate type | Typical check | Worth knowing |
|---|---|---|
| Biometric turnstiles (tripod, swing, full-height or optical) | Face on a tablet or IP camera | IP cameras capture several faces at once where queues build (Standard and Premium) |
| Doors and electric locks | Face or fingerprint at a station beside the door | Existing locks and controllers connect through the access control integration |
| Site gates | Face recognition gate on a phone or tablet | On Standard and Premium, offline mode keeps check-ins recording where there's no signal |
| Vehicle barriers and bollards | Licence plate read by an IP camera of 2 MP or more | Licence plate recognition is on Premium, and vehicle gates use the NCheck Surveillance app (see parking and gate control) |
| High-security doors | Iris, or two biometrics at one door | Suits vaults, laboratories and other restricted rooms |
Industries that use biometric gates.
| Industry | Where the gate is | What NCheck adds |
|---|---|---|
| Construction | Site gate and turnstiles | Biometric access control for construction sites, with subcontractors on the same gate as staff and, on Premium, safety-helmet detection at check-in |
| Mining | Pit and lamp-room entrances | Face check-in, since dirty hands make fingerprints unreliable underground |
| Oil and gas | Site entrance and muster point | Contractors grouped separately, with check-ins at the muster point showing who has arrived |
| Manufacturing and warehouses | Turnstiles at shift change | Several stations, or one IP camera, clear a whole shift quickly |
| Apartments and gated communities | Resident and guest gate | Residents, staff and expected guests on one log through visitor management |
| Schools | Main entrance | Staff and visitors on the same system, with a non-biometric option where needed |
| High security and precious metals | Vault and refinery doors | An air-gapped server keeps every gate decision inside the site |
Gate access that keeps working offline.
With NCheck On-Premises, gate decisions are made on your own network, so a dropped internet connection doesn't lock people out, and the server can run air-gapped for restricted sites. Templates are encrypted, and event photos can be deleted automatically after a period you set.
“Face recognition works well with a normal camera too. Convenient, cost-effective and highly accurate — face, fingerprint and iris.”

Frequently asked questions.
What is a biometric gate?
It's a gate, turnstile or barrier that opens only after a reader confirms who someone is from their face, fingerprint or iris. It replaces cards and PINs, which can be lent or shared, and keeps a record of everyone who passed through. Our post on what a physical access control system is covers the wider picture.
Can NCheck work with our existing turnstiles and barriers?
Usually, yes. NCheck triggers gate hardware over relay, Wiegand, HTTP or MQTT, so most electric locks, turnstiles and barriers can stay in place. Tell us the make and model and we'll confirm before you commit, and there's more on the protocols in biometric systems for automatic gate opening.
What happens if the biometric check fails or the system goes down?
A person can be given a second way through, such as an RFID or barcode card on Standard and above. On-premises installations keep making gate decisions on the local network if the internet drops, and every gate should keep a physical override for safety.
Can visitors and contractors use the same gate?
Yes. Visitors check in with an electronic pass or a biometric check at the same entrance, and contractors can be grouped so their access is limited to the gates and hours they need.
How much does biometric gate access cost?
Access control is included from the Standard plan, billed per employee per month, and runs on cameras and scanners you may already own. Licence plate recognition for vehicle barriers is on Premium and uses the NCheck Surveillance app. Current prices are on the pricing page.
Is biometric gate access allowed under data protection law?
In most countries it is, with conditions on consent and how long the data is kept. NCheck stores encrypted templates, never photos, and a person's template can be deleted when they leave. The compliance pages cover GDPR, US state laws, India's DPDP Act, Türkiye's KVKK and the Gulf PDPL. This is general guidance, not legal advice.
