How to use QR codes for remote door access requests

Short answer

Place a QR code next to a locked door — a gate, office entrance, co-working space, or building lobby. When someone scans it, they fill out a short form with their first name and the reason they need access. A confirmation message is displayed, and the request is logged so anyone with dashboard access can review it and decide whether to unlock the door remotely.

How it works

Traditional buzzer systems require someone to be physically present or connected to an intercom. A QR-based access request replaces this with a simple scan-and-submit flow that works on any smartphone — no app download, no account creation.

The visitor experience

1. The visitor scans the QR code posted at the door
2. A form asks for their first name and reason for the visit
3. They tap submit and see a "Thank you — your request has been received" confirmation
4. The person with access reviews the request on their dashboard and decides whether to grant entry

What you capture

Each submission is logged as a tracked event with full device and location metadata:

• First name — who is requesting access
• Reason — why they need the door unlocked
• Timestamp — when the request was made
• Device type — mobile, tablet, or desktop
• Location — approximate geo from the device
• Visit history — whether this person has scanned before (returning visitor detection)

Setting it up in Linkbreakers

You can build this entire flow in under two minutes using the "Build with AI" feature:

1. Click Create and select Build with AI
2. Describe what you need: "Create a QR code for visitors to request a door unlock. Collect their first name and reason for access, then show a thank you message."
3. The AI sets up the link, form fields, and confirmation page automatically
4. Download or print the QR code and place it at your entrance

Alternatively, build it manually:

1. Create a new link with a Thank You Page as the destination
2. Add a Form step to the workflow with two fields: "Your name" (short text) and "Reason for access" (short text)
3. Connect the form to the thank you page as the exit step
4. Optionally enable Slack notifications or webhooks to get instant alerts when someone submits

Limits and caveats

• This system collects access requests — it does not physically unlock a door. You need a separate smart lock or access control system to act on the request.
• If you need real-time push notifications, connect a webhook or Slack integration to the link so you're alerted the moment someone submits.
• For higher security, add a password step before the form so only people with a shared code can submit a request.

Frequently asked questions

Can I get notified instantly when someone requests access?

Yes. Connect a Slack integration or webhook to the link. Every form submission triggers a real-time notification with the visitor's name, reason, device info, and timestamp.

Does the visitor need to download an app?

No. The QR code opens a mobile-optimized web page directly in the phone's browser. No app install, no account creation — just scan, fill out the form, and submit.

Can I see who has requested access before?

Yes. Linkbreakers tracks visitors across scans. If someone has scanned any of your QR codes before, they are marked as a returning visitor and their full history is visible in the visitor analytics dashboard.

Can I customize what happens after the form is submitted?

Yes. You can show a thank you message with a custom title and description, redirect to any URL, or chain additional steps like a contact card download.

Is this secure enough for building access?

This is a request system, not an access control system. It is best suited for low-to-medium security scenarios — shared office spaces, co-working lobbies, gated communities, or delivery entrances. For high-security environments, pair it with proper access control hardware and use the password step for pre-screening.
