Access Control

Take control of access to your work site

See any worker's or resource's access status instantly, from any device, along with what is blocking or allowing entry. If something expires today, they don't get in tomorrow — with no action needed from your team.

From document status to access decision

In real time, from web or mobile, with every entry logged.

Find the resource

A worker arrives at your site. The supervisor looks them up in Twind via QR code or by work site, company, name or ID number, from web or app.

Check access instantly

Based on compliance status and your work site hierarchy, see access status at a glance: allowed or denied, and why.

Decide and log

Every contractor and visitor entry and exit is logged and can be exported to Excel. Always in sync with document status: if the documentation changes, the access status updates.

Make fast, consistent access decisions

Instant access information

See at a glance whether access is allowed, partial or denied, by colour and in detail. Nothing to decipher.

You know what's blocking entry

When access isn't allowed, you see the critical requirements preventing it, whether pending or rejected.

Full logging and traceability

Every contractor and visitor entry and exit is logged and exportable to Excel, audit-ready.

From any device

Check access from the web or your mobile. Take control with you in the field, with the Twind app.

Beyond verification

Restrictive or permissive mode

Block entry if any critical requirement is missing, or show the breakdown by contract and activity. The reason is displayed, so everyone is informed.

Temporary authorisations

Grant or block access on an exceptional basis, with automatic expiry and full traceability.

Visitor management and scheduling

Register visitors in seconds or schedule them by date: they get their QR by email and security checks them in with a single action.

Real-time presence

See who is present for emergencies or drills, with a full history exportable to Excel.

QR access card

Identity, activity, company and status in a unique QR code per resource. A version customisable with your logo is available.

Available in the Twind App

Take access control into the field with the Twind app

Manage access, visits and temporary authorisations from your mobile, with the same checks as the web, even in remote areas with no signal, with no permanent gatehouse or at secondary entrances.

Unattended mode: A single device at the entrance: contractors and visitors check themselves in via QR code or manual search.
Offline-first: Zero interruptions when the internet drops — ideal for remote, low-connectivity environments.
The same checks as the web: A contractor blocked in Twind is blocked in the app too.

Frequently Asked Questions

What you need to know about access control

Does access control cost extra?

−

Access control is included when you subscribe to the Twind platform. Some advanced features, such as field use via the mobile app, are purchased separately. Our sales team will explain what each option includes based on how you operate.

Does it work on construction sites or areas with no signal?

Yes. The Twind app has an offline mode that lets you keep verifying access without a connection and syncs the records once signal is restored. Configuration details depend on your type of facility.

How is this different from a traditional access control system (turnstiles, cards, biometrics)?

Your system verifies identity. Twind's access control module verifies compliance. You can have the right card and still be blocked because your health and safety training expired yesterday. It's the difference between "this person exists in the system" and "this person is cleared to work on your site today under safety regulations".

Can it integrate with turnstiles, barriers or plant systems?

Twind offers an API to integrate with physical access control systems and ERPs. Available integrations and timelines depend on your technical environment.

How long does it take to get up and running?

It depends on the number of work sites and contractors, and on the documentation you already have uploaded. Our implementation team will give you a plan with specific timelines once they understand your case.

What if I haven't uploaded all the documentation yet?

The module works from day one: it shows compliance status based on whatever has been uploaded and flags what's missing. As the documentation is completed, access status updates automatically.

Can I block someone's access even if their documentation is in order?

Yes: with temporary authorisations you can deny access on an exceptional basis, with a logged reason and an expiry window. Our sales team can show you how it works in the demo.
