# How to use QR codes for remote door access requests

> Place a QR code at your entrance so visitors can request a door unlock by submitting their name and reason — no app install needed, instant notification to anyone with access.

:::try-ai-prompt {"prompt":"Create a QR code that visitors scan to request a remote door unlock. Collect their first name and the reason they need access, then show a thank you message.","description":"Try building a door access request workflow with the AI builder."}:::

## 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 "Assistant" feature:

1. Click **Create** and select **Assistant**
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](https://linkbreakers.com/help/article/how-do-webhooks-work-in-linkbreakers) or [Slack integration](https://linkbreakers.com/help/article/how-to-set-up-slack-notifications-for-qr-code-scans) 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](https://linkbreakers.com/help/article/how-to-track-how-many-people-scanned-your-qr-code).

### 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.
