# Sending a Registration Code by Email

{/* category: Check-In Devices */}

Instead of reading a code aloud or copying it manually, you can send a setup invitation email directly to the person who will be setting up the device. The email includes the registration code and a direct link to the check-in app.

## When to Use Email Invitations

Email invitations are useful when:

* The person setting up the device is in a different location
* You want to schedule device setup without being present
* You are sending instructions to a non-technical operator who needs a clear setup link

Unlike codes generated from the **Generate Code** button (which expire after 15 minutes), email invitation codes do **not expire** — they remain valid until used.

***

## Sending the Invitation Email

1. Navigate to **Check-In Devices** in the admin panel
2. Click **Send Setup Email**
3. Fill in the invitation form:
   * **Email address** (required) — the recipient will receive the setup link here
   * **Recipient name** (optional) — personalizes the email greeting
4. Click **Send**

The system generates a unique registration code and sends an email containing:

* Your organization's name and logo (from your whitelabel settings)
* A direct link to **`https://scan.idpage.link`**
* The registration code to enter during setup
* Step-by-step setup instructions

The email is delivered in the language configured in your organization's settings (English, French, or Arabic).

## What the Recipient Does

When the recipient receives the email:

1. Open the link to `https://scan.idpage.link` on the device
2. Follow the setup wizard (as described in Registering a New Device)
3. Enter the code from the email when prompted

***

## Bounce Detection

If the recipient's email address is invalid and the email bounces, the admin panel will show an error notification. Check the email address and try again.

***

## Security Note

Each registration code can only be used **once**. After it has been used to register a device, the code is invalidated and cannot be reused. If the code is used by the wrong device by mistake, you can **revoke** the device from the admin panel and generate a new code.
