# Visitor Sign-In card

> Canonical HTML: https://screenrig.ai/docs/cards/visitor-sign-in/

Welcome visitors with a QR code for your supplied check-in page.

Venue welcome wording sits beside a stationary QR code that opens your supplied visitor check-in destination on a phone. On their phone, visitors complete the supplied workflow. Handoff support comes from a readable address and an assistance note.

## Live card

This card is drawn in your browser by the same code the Players run, with sample data.

Category: Messages. Tags: QR codes, Lobbies and reception, Wayfinding and directories.

## Layouts

This fullscreen card fills the whole screen in landscape or portrait and is not placed as a corner, chip, or strip.

Layouts: full. Forms: landscape, portrait.

[Card layouts, themes and publishing](/docs/cards/). [Browse the cards](/apps/#cards).

## Data and privacy

This card uses its configured properties and live card data.

The card displays a supplied link. Visitor details, feedback responses and questions are handled by the supplied destination.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

### Static properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `title` | string | `"Visitor sign-in"` | maxLength: `80` |  |
| `venue` | string | `""` | maxLength: `100` |  |
| `headline` | string | `"Welcome. Check in here."` | maxLength: `140` |  |
| `message` | string | `"Scan to open visitor check-in on your phone."` | maxLength: `240` |  |

### Dynamic properties

| Name | Type | Default | Values and limits | Description |
| --- | --- | --- | --- | --- |
| `url` | string | `""` | maxLength: `512` | Supplied HTTP or HTTPS destination. The QR code opens this exact address; the destination owns the workflow. |
| `addressLabel` | string | `""` | maxLength: `120` | Optional readable address below the code; when empty, the supplied address is shown without scheme, query or fragment. |
| `help` | string | `"Need a hand? Please ask at reception."` | maxLength: `180` |  |
| `updatedAt` | string | `""` | maxLength: `40` |  |

## Canvas example

Add this item to a playlist page’s `primitives`. [Publish the playlist and assign a screen](/docs/cards/#publish-a-card-canvas).

```json
{
  "id": "visitor-sign-in",
  "primitive": "card",
  "card": "visitor-sign-in",
  "major": 1,
  "params": {
    "theme": "neomustard"
  },
  "rect": {
    "x": 0,
    "y": 0,
    "width": 1920,
    "height": 1080
  },
  "layer": 0,
  "content_fit": "fill",
  "data": "example-key"
}
```

## Write live data

The canvas example binds its `data` field to `example-key`. That value is a data key: a name this canvas item chooses, not the name of the card. Give each canvas item its own key when items should show different data, or share one key when they should show the same data. Keys are scoped to the project, follow the K/V key grammar, and cannot start with `feed:`.

Create this document before showing the card, then replace it to update the screen without republishing. Writes to a key that live canvas items bind are checked against each bound card’s dynamic properties. Use the same project as the playlist.

Save the document as `card-data.json`. The CLI reads the document itself, with no wrapper:

```json
{
  "url": "",
  "addressLabel": "",
  "help": "Need a hand? Please ask at reception.",
  "updatedAt": ""
}
```

```console
screenrig card-data put example-key --file card-data.json
```

Or call the API directly. The API wraps the same document in a `document` field. An agent token already names its project, so no project header is sent; if you send `ScreenRig-Project`, it must match the token’s project. Supply your API authorization through the environment; see [API authentication](/docs/authentication/).

```console
curl --request PUT "https://api.screenrig.ai/api/card-data/example-key" \
  --header "Authorization: Bearer $SCREENRIG_TOKEN" \
  --header "Content-Type: application/json" \
  --data '{"document":{"url":"","addressLabel":"","help":"Need a hand? Please ask at reception.","updatedAt":""}}'
```
