Kenteken Check

Lightweight embed widget for inline kentekenchecks on any website. Shows public vehicle details from the Dutch RDW vehicle register — merk, model, APK date, and more. A vanilla TypeScript custom element with Shadow DOM — no framework, iframe, or scanner required.

Configure fields, theme, and copy embed code: scankenteken.nl/kenteken-check-embed

Embed

<script async src="https://cdn.scankenteken.nl/kenteken-check/v1/embed.js"></script>
<kenteken-check></kenteken-check>

Attributes

| Attribute | Default | Values | |---|---|---| | fields | brand,apk,link | comma-separated: brand, apk, year, price, euro, link | | theme | auto | light, dark, auto | | plate | — | pre-fill and auto-lookup, e.g. RJ-123-X |

Examples

Show bouwjaar and price alongside brand and APK:

<kenteken-check fields="brand,apk,year,price"></kenteken-check>

Pre-filled, dark theme:

<kenteken-check plate="RJ-123-X" theme="dark"></kenteken-check>

ESM module

For bundlers (Vite, Next.js, etc.) or a module script on the page:

import { defineKentekenCheck } from 'kenteken-check-embed'

defineKentekenCheck()

<kenteken-check fields="brand,apk,link"></kenteken-check>

CDN module import (no bundler):

<script type="module">
  import { defineKentekenCheck } from 'https://cdn.scankenteken.nl/kenteken-check/v1/index.js'
  defineKentekenCheck()
</script>
<kenteken-check></kenteken-check>

The classic script tag embed (embed.js) still works and auto-registers the element:

<script async src="https://cdn.scankenteken.nl/kenteken-check/v1/embed.js"></script>

Local development

npm install
npm run build
npm run serve

Open the live configurator to preview and copy embed code:

For local development, the same configurator is available at http://localhost:3000/configurator/ after npm run serve.

Watch mode:

npm run dev

Data source

Vehicle data comes from the public RDW (Rijksdienst voor het Wegverkeer) open vehicle register. The widget fetches it via https://api.scankenteken.nl/api/vehicles/:plate. Rate limiting and caching are handled server-side.

ScanKenteken is not part of the RDW. No personal owner data is shown.
